Accounting Policies [Abstract]	'
SIGNIFICANT ACCOUNTING POLICIES	'
	SIGNIFICANT ACCOUNTING POLICIES
	Accounting Estimates
	Preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and reported amounts of net revenues and expenses during the reporting period. Financial statement line items that include significant estimates consist of goodwill, net intangibles, accrued restructuring costs, certain tax accounts, certain accrued liabilities and the allowance for uncollectible accounts receivable. Changes in the facts or circumstances underlying these estimates could result in material changes, and actual results could differ from those estimates. These changes in estimates are recognized in the period they are realized.
	Principles of Consolidation and Basis of Presentation
	The financial statements include our accounts consolidated with our wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. Unless otherwise stated, current and prior period results in our consolidated statements of operations and cash flows and these notes reflect our results from continuing operations and exclude the effect of current and prior period discontinued operations. See Note 4 to our consolidated financial statements for additional information and related disclosures regarding our discontinued operations. Certain prior year amounts have been reclassified to conform to current year presentation.
	Cash and Equivalents and Restricted Cash
	Cash and equivalents consist of cash on hand. Cash balances that are legally restricted as to usage or withdrawal are separately included in “Prepaid expenses and other current assets” on our consolidated balance sheets. At December 31, 2013 and 2012, we had $0.0 million and $0.6 million of restricted cash, respectively.
	Accounts Receivable and Allowance for Doubtful Accounts
	Included in accounts receivable at December 31, 2013 and 2012 was earned but unbilled revenue of approximately $5.7 million and $6.7 million, respectively, which results from non-calendar month billing cycles and the one-month lag in billing of certain of our services. Earned but unbilled revenue is billed within 30 days. Provision for doubtful accounts was approximately $0.5 million, $1.1 million and $0.6 million in 2013, 2012 and 2011, respectively. Write-offs against the allowance for doubtful accounts were $0.6 million, $0.9 million and $0.9 million in 2013, 2012 and 2011, respectively. Our allowance for doubtful accounts represents reserves for receivables that reduce accounts receivable to amounts expected to be collected. The allowance for doubtful accounts was approximately $0.8 million, $0.8 million and $0.6 million as of December 31, 2013, 2012 and 2011, respectively. Management uses significant judgment in estimating uncollectible amounts. In estimating uncollectible amounts, management considers factors such as historical and anticipated customer payment performance and industry-specific economic conditions. Using these factors, management assigns reserves for uncollectible amounts by accounts receivable aging categories to specific customer accounts.
	Property and Equipment
	Property and equipment are recorded at cost. Depreciation is recorded under the straight-line method over the estimated useful lives of the assets, commencing when the assets are placed in service. The estimated useful lives are five to seven years for furniture and fixtures, two to five years for software and three to five years for computer servers and Internet and telecommunications equipment. The cost of installation of equipment is capitalized, as applicable. Amortization of assets recorded under capital leases is included in depreciation. Assets recorded under capital leases and leasehold improvements are depreciated over the shorter of their useful lives or the term of the related lease.
	Research and Development
	Research and development expenses primarily related to developing new services, features and enhancements to existing services that do not qualify for capitalization are expensed as incurred.
	Software Development Costs
	We capitalize certain costs incurred to develop software features used as part of our service offerings within “Property and Equipment, Net” on our consolidated balance sheets. For the years ended December 31, 2013, 2012 and 2011, we capitalized approximately $17.5 million, $15.3 million and $15.3 million, respectively, of these costs. We amortize these capitalized costs on a straight-line basis over the estimated life of the related software, not to exceed five years. Depreciation expense recorded for developed software for the years ended December 31, 2013, 2012 and 2011, was approximately $13.7 million, $12.1 million and $10.2 million, respectively.
	Goodwill
	Goodwill is subject to an impairment assessment performed at the reporting unit level, at least annually and more frequently if indicators of impairment are identified. Our reporting units are our operating segments, North America, Europe and Asia Pacific. We utilize December 31 as our annual date to perform the assessment and adopted the qualitative goodwill impairment assessment standard, applied as of December 31, 2012. Under this standard, management evaluates whether it is more likely than not that the carrying value of a reporting unit exceeds its fair value. Factors utilized in this qualitative assessment include the results of the most recent impairment test, economic factors impacting the conferencing and collaboration industry, current and long-range forecasted financial results and changes in the strategic outlook of the reporting unit. If it is determined that fair value more likely than not exceeds carrying value, then goodwill is not considered impaired and no quantitative impairment test is required for that reporting unit. If it is more likely than not that carrying value exceeds fair value, we proceed with the quantitative two-step impairment assessment. The first step is to identify potential goodwill impairment by comparing the calculated estimated fair value of the reporting unit to its carrying amount. The second step measures the amount of the impairment based upon a comparison of “implied fair value” of goodwill with its carrying amount.
	As a result of the acquisitions made in 2013, we elected to perform step one of the quantitative impairment test for each of our reporting units for our December 31, 2013 assessment. Based on our quantitative assessment this year, the estimated fair value of our Europe and Asia Pacific reporting units substantially exceeded their respective carrying values, while the estimated fair value of our North America segment exceeded its carrying value by 20%. No impairment of goodwill was identified in any of the years ended December 31, 2013, 2012 and 2011.
	Valuation of Long-Lived Assets
	We evaluate the carrying values of long-lived assets when significant adverse changes in the economic value of these assets require an analysis, including property and equipment and other intangible assets. A long-lived asset is considered impaired when its fair value is less than its carrying value. In that event, a loss is calculated based on the amount the carrying value exceeds the future cash flows, as calculated under the best-estimate approach, of such asset. We believe that long-lived assets in our consolidated balance sheets are appropriately valued. Asset impairments were $1.2 million, $0.9 million and $0.5 million during 2013, 2012 and 2011, respectively, and are recognized as “Asset impairments” in our consolidated statements of operations.
	Investments
	In March 2013, we invested $1.0 million in a privately-held cloud solutions provider. In September 2012, we invested $1.0 million in a privately-held cloud service marketplace company by purchasing a convertible promissory note, which was repaid to us in January 2014 for the principal balance plus accrued interest at an annual rate of 8%.
	These investments are accounted for under the cost method and are periodically assessed for other-than-temporary impairment using financial results, economic data and other quantitative and qualitative factors deemed applicable. In the event an other-than-temporary impairment occurs, an impairment loss equal to the difference between the cost basis and the fair value will be recognized. After the effects of foreign currency exchange rate fluctuations and accrued interest, our cost method investments had a total carrying value of $2.1 million and $1.9 million as of December 31, 2013 and 2012, respectively. These amounts were included as a component of “Other assets” on our consolidated balance sheets for each period presented, except for the convertible promissory note, which was included as a component of “Prepaid expenses and other current assets” as of December 31, 2013.
	In June 2011, we invested approximately $1.0 million in a privately-held conferencing company. During December 2013, this investment changed from a historical cost investment to an available-for-sale asset when that company’s shares began trading publicly on a foreign stock exchange. The fair value of this investment was based on the quoted price of our shares on that foreign exchange at the measurement date of December 31, 2013. This investment is also subject to fluctuations in foreign currency exchange rates. Any related gains or losses related to the market value of the shares or fluctuations in foreign currency are excluded from earnings until realized and reported as a component of “Accumulated other comprehensive gain” on our consolidated balance sheets. After the effects of foreign currency exchange rate fluctuations and adjustments to the quoted market value, the available-for-sale investment had a market value of $3.5 million, which was included as a component of “Prepaid expenses and other current assets” as of December 31, 2013.
	Revenue Recognition
	We recognize revenues when persuasive evidence of an arrangement exists, services have been rendered, the price to the buyer is fixed or determinable and collectability is reasonably assured. Revenues from continuing operations consist primarily of usage fees generally based on per minute, and prior to our discontinued reclassifications, per fax page or per transaction methods. To a lesser extent, we charge subscription-based and license fees and have fixed-period minimum revenue commitments related to our SaaS-based collaboration products. These subscription-based fees are considered service arrangements per the authoritative guidance; accordingly, fees related to subscription agreements are recognized ratably over the contract term, which is typically 12 to 24 months. We also include per minute usage fees generated through the use of our SaaS-based collaboration products in SaaS revenues. These usage fees, which are generated if a customer elects to use either minutes in excess of the contractual amount or of a type not included in the arrangement, are recognized as incurred by the customer, consistent with our other per minute usage fees. In addition, SaaS revenues may also include set-up fees, which are recognized ratably over the contract term or the expected customer life, whichever is longer. Unbilled revenue consists of earned but unbilled revenue that results from non-calendar month billing cycles and the one-month lag time in billing related to certain of our services. Deferred revenue consists of payments made by customers in advance of the time services are rendered. Incremental direct costs incurred related to deferred revenue are deferred over the life of the contract and are recorded in “Prepaid expenses and other current assets” in our consolidated balance sheets.
	USF Charges
	In accordance with FCC rules, we are required to contribute to the federal USF for some of our solutions, which we recover from our applicable customers and remit to the USAC. We present the USF charges that we collect and remit on a net basis, with both collections from our customers and the amounts we remit, recorded in "Net revenues". Had we presented USF charges on a gross basis, net revenues and cost of revenues would have been $27.1 million, $32.0 million and $30.4 million higher for the years ended December 31, 2013, 2012 and 2011, respectively.
	Foreign Currency Translation
	The assets and liabilities of subsidiaries with a functional currency other than the U.S. Dollar are translated at rates of exchange existing at our consolidated balance sheet dates. Revenues and expenses are translated at average rates of exchange prevailing during the year. The resulting translation adjustments are recorded in the “Accumulated other comprehensive gain” component of shareholders’ equity. In addition, certain of our intercompany loans with foreign subsidiaries are considered to be permanently invested for the foreseeable future. Therefore, foreign currency exchange gains and losses related to these permanently invested balances are recorded in the “Accumulated other comprehensive gain” component of shareholders’ equity in our consolidated balance sheets.
	Treasury Stock
	All treasury stock transactions are recorded at cost, and all shares of treasury stock repurchased are retired. During the year ended December 31, 2013, we repurchased approximately 0.1 million shares of our common stock in the open market for approximately $1.4 million at an average price of $10.54 per share. During the year ended December 31, 2012, we repurchased approximately 3.2 million shares of our common stock in the open market for approximately $27.9 million at an average price of $8.81 per share.
	During the years ended December 31, 2013 and 2012, we redeemed 215,387 and 246,735 shares, respectively, of our common stock to satisfy certain of our employees’ tax withholdings due upon the vesting of their restricted stock grants and remitted approximately $2.7 million and $2.0 million, respectively, in taxes on our employees’ behalf.
	Preferred Stock
	We have 5.0 million shares of authorized $0.01 par value preferred stock, none of which are issued or outstanding. Under the terms of our amended and restated articles of incorporation, our board of directors is empowered to issue preferred stock without shareholder action.
	Income Taxes
	Income taxes are determined under the asset and liability method as required by ASC 740, “Income Taxes”. Under this method, deferred tax assets and liabilities are recognized based upon the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary items are expected to be recovered or settled. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts more likely than not to be realized. To the extent we establish a valuation allowance or increase this allowance in a period, an expense is recorded within the income tax provision in our consolidated statements of operations. Under current accounting principles, the impact of an uncertain income tax position on the income tax return must be recognized at the largest amount that is more likely than not to be sustained upon audit by the relevant taxing authority. Accrued interest related to uncertain tax positions is recorded as "Interest expense" in our consolidated statements of operations. See Note 16 to our consolidated financial statements for additional information and related disclosures regarding our income taxes.
	Restructuring Costs
	Restructuring reserves are based on certain estimates and judgments related to severance and exit costs, contractual obligations and related costs and are recorded as “Restructuring costs” in our consolidated statements of operations. See Note 3 to our consolidated financial statements for additional information and related disclosures regarding our restructuring costs.
	Acquisition-related Costs
	Acquisition-related costs reflected in our consolidated statements of operations include, but are not limited to, transaction costs such as banking, legal, accounting and other professional fees directly related to acquisitions, termination and related costs for transitional and certain other employees, integration-related professional fees and other post-business combination expenses associated with our business acquisitions.
	The following table summarizes acquisition-related costs incurred during the year ended December 31, 2013 (in thousands):
		2013
	Professional fees	$	2,439
	Release of indemnification asset	1,129
	Integration-related costs	1,824
	Total acquisition-related costs	$	5,392
	For further discussion of the indemnification asset and related costs see Notes 12 and 16 to our consolidated financial statements.
	Advertising Costs
	We expense production costs associated with an advertisement the first time the advertising takes place. All other advertising-related costs are expensed as incurred. We expense advertising costs as advertising space or airtime is used. Total advertising expense in 2013, 2012 and 2011 was $6.1 million, $8.9 million and $16.9 million, respectively. As of December 31, 2013 and 2012, we had $0.0 million and $0.3 million of prepaid advertising, respectively.
	Legal Contingencies
	We are involved from time to time in certain legal matters and subject to other claims as disclosed in Note 14 to our consolidated financial statements. We accrue an estimate for legal contingencies when we determine that it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. These estimates are developed in consultation with outside counsel handling these matters and based upon an analysis of potential results, assuming a combination of litigation and settlement strategies.
	New and Recently Adopted Accounting Pronouncements
	In July 2013, the FASB issued ASU No. 2013-11, “Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists,” which requires an unrecognized tax benefit to be presented as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss or a tax credit carryforward that the entity intends to use and is available for settlement at the reporting date. This guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. As the guidance is consistent with our current reporting practices, it will not have a material impact on our consolidated financial position or results of operations.

	RESTRUCTURING COSTS
	Below is a reconciliation of the beginning and ending liability balances related to our restructuring efforts for the years ended December 31, 2013, 2012 and 2011. Provision for restructuring costs from continuing operations were $3.5 million, $0.6 million and $0.8 million, in 2013, 2012 and 2011, respectively. The expenses associated with these activities are reflected in “Restructuring costs” in our consolidated statements of operations. Cash payments for restructuring costs from continuing operations were $2.5 million, $3.2 million and $6.8 million in 2013, 2012 and 2011, respectively. The components included in the reconciliation of the liability balances include costs related to our continuing and discontinued operations (in thousands):

	Realignment of Workforce – 2013
	During 2013, we recorded restructuring expenses of $3.5 million. This amount includes net adjustments of $0.1 million related to prior year realignments, as detailed below. For the 2013 realignment, we recorded $3.2 million of severance costs and eliminated approximately 60 positions in an effort to consolidate and streamline various functions of our workforce. We also recorded $0.2 million in contract termination costs associated with this realignment. On a segment basis, these restructuring costs totaled $1.2 million in North America, $2.0 million in Europe and $0.2 million in Asia Pacific. Our reserve for the 2013 realignment was $1.9 million at December 31, 2013, which we anticipate will be paid within two years.
	Realignment of Workforce – 2012
	During 2012, we eliminated approximately 50 positions in an effort to consolidate and streamline various functions of our workforce. To date, we have recorded $2.0 million of severance costs, including $0.1 million in adjustments recorded in 2013. On a segment basis, these restructuring costs totaled $1.0 million in North America, $0.6 million in Europe and $0.4 million in Asia Pacific. There is no remaining reserve for the 2012 realignment at December 31, 2013.
	Realignment of Workforce – 2010
	During 2010, we eliminated approximately 165 positions in an effort to consolidate and streamline various functions of our workforce. To date, we have recorded $9.2 million of severance costs and $0.6 million of lease termination costs associated with this realignment. We have also recorded $1.8 million of asset impairments in connection with these restructuring efforts. In addition, we recorded $0.9 million of exit costs related to marketing efforts abandoned during 2010 and $0.5 million of exit costs related to the reorganization of our operating structure subsequent to the sale of our PGiSend messaging business in 2010 to Easylink as restructuring costs. On a segment basis, these restructuring costs totaled $7.7 million in North America, including accelerated vesting of restricted stock with a fair market value of $0.2 million, $2.3 million in Europe and $1.2 million in Asia Pacific. Included in these amounts was an adjustment to reduce severance and exit costs by $0.1 million in Europe, which was recorded during 2013. There is no remaining reserve for the 2010 realignment at December 31, 2013.
	Realignment of Workforce – 2009
	During 2009, we executed a restructuring plan to consolidate and streamline various functions of our workforce. As part of these consolidations, we eliminated approximately 500 positions. To date, we have recorded total severance and exit costs of $14.6 million associated with this realignment, including accelerated vesting of restricted stock with a fair market value of $0.2 million in North America. We have also recorded $4.5 million of lease termination costs associated with office locations in North America and Europe. On a segment basis, these restructuring costs totaled $12.5 million in North America, $6.0 million in Europe and $0.6 million in Asia Pacific. During 2013, we updated assumptions regarding lease termination costs, resulting in a $0.1 million expense in North America, which is also included in the cumulative costs related to the 2009 realignment presented above. Our reserve for the 2009 realignment, comprised of lease termination costs, was $0.3 million at December 31, 2013. We anticipate these costs will be paid within the next two years.

	On October 21, 2010, we completed the sale of our PGiSend messaging business through the sale of all of the issued and outstanding equity interests in our wholly-owned subsidiaries, Xpedite and Premiere Global Services (UK) Limited, and the sale of certain assets of Premiere Conferencing (Canada) Limited to EasyLink for an aggregate purchase price of $105.0 million, with a working capital target that was finalized in the first quarter of 2011, resulting in an additional payment from EasyLink of $1.8 million.
	We allocated interest expense related to interest recognized on uncertain tax positions specific to our PGiSend discontinued operations in 2011, 2012 and 2013.
	The results of discontinued operations for 2011 include an income tax benefit of $7.3 million. This benefit includes approximately $6.0 million relating to changes in estimates of the tax provision that resulted from the finalization of the actual tax basis purchase price allocation received in the third quarter from EasyLink in connection with our PGiSend sale.
	The results of discontinued operations for 2013 and 2012 related to ongoing administration and resolution of residual liabilities not assumed by EasyLink in connection with the PGiSend sale.
	Maritime Notification and Reminder Solutions
	During the year ended December 31, 2010, we classified our Maritime Notification and Reminder solutions operations as a disposal group held for sale. This disposal group consisted of all customers using these non-conferencing, ship-to-shore communication services targeted specifically toward shipping vessels that we resell through our Japanese subsidiary. As of December 31, 2011, this disposal was completed, and no assets or liabilities of the disposal group remain.

In connection with this amendment, we incurred $1.3 million in debt issuance costs, which were capitalized and included within "Other assets" in our consolidated balance sheets and will be amortized as an adjustment to "Interest expense" over the remaining life of the credit facility. Our credit facility consists of a $350.0 million revolver, a $50.0 million Term A loan and an uncommitted $75.0 million accordion feature, which allows for additional credit commitments up to a maximum of $475.0 million, subject to the credit facility terms and conditions. Our subsidiary, ATS, is the borrower under our credit facility, with PGi and certain of our material domestic subsidiaries guaranteeing the obligations of ATS under the credit facility, which is secured by substantially all of our assets and the assets of our material domestic subsidiaries. In addition, we have pledged as collateral all of the issued and outstanding stock of our material domestic subsidiaries and 65% of the issued and outstanding stock of our material foreign subsidiaries. Proceeds drawn under our credit facility can be used for working capital, capital expenditures, acquisitions and other general corporate purposes. The annual interest rate applicable to borrowings under our credit facility, at our option, is (1) the base rate (the greater of either the federal funds rate plus one-half of one percent, the prime rate or one-month LIBOR plus one and one-half percent) plus an applicable percentage that varies based on our consolidated leverage ratio at quarter end, or (2) LIBOR (or, if applicable, the rate designated in the credit facility for certain foreign currencies) for one, two, three or six months adjusted for a percentage that represents the Federal Reserve Board’s reserve percentage plus an applicable percentage that varies based on our consolidated leverage ratio at quarter end. The applicable percentage for base rate loans and LIBOR loans were 1.25% and 2.25%, respectively, at December 31, 2013 under our credit facility. Our interest rate on LIBOR loans, which comprised materially all of our outstanding borrowings as of December 31, 2013, was 2.45%. In addition, we pay a commitment fee on the unused portion of our credit facility that is based on our consolidated leverage ratio at quarter end. As of December 31, 2013, the rate applied to the unused portion of our credit facility was 0.35%. Our credit facility contains customary terms and restrictive covenants, including financial covenants. At December 31, 2013, we had $270.1 million of borrowings and $5.3 million in letters of credit outstanding under our credit facility.

	EQUITY-BASED COMPENSATION
	We may issue restricted stock awards, stock options, stock appreciation rights, restricted stock units and other stock-based awards to employees, directors, non-employee consultants and advisors under our amended and restated 2004 long-term incentive plan and our amended and restated 2000 directors stock plan, each plan as amended. We issue both service and performance-based restricted stock awards to employees. Performance-based restricted stock awards are issued to certain key executives and vest based on financial performance metrics over the requisite service period. Options issued under these plans, other than the directors stock plan, may be either incentive stock options, which permit income tax deferral upon exercise of options, or non-qualified options not entitled to such deferral. The compensation committee of our board of directors administers these stock plans.
	Our 2004 plan provides for a total of 8.0 million shares authorized for issuance. The maximum number of stock-based awards that we may grant under our 2004 plan during any one calendar year to any one grantee is 1.0 million shares.
	Our directors stock plan provides for a total of 2.5 million shares authorized for issuance. Only non-employee directors can participate in, and we may only grant restricted stock and non-qualified stock options under, our directors plan.
	Equity-based compensation expense is measured at the grant date, based on the fair value of the award, and is recognized over the vesting periods. Included in the expense amounts are employer-related costs for taxes incurred upon vesting of awards which do not impact "Additional Paid-In Capital." The following table presents total equity-based compensation expense for restricted stock awards and non-qualified stock options included in the line items below in our consolidated statements of operations (in thousands):
		Years Ended December 31,
		2013			2012			2011
	Cost of revenues	$	614		$	482		$	169

	Equity-based compensation expense	$	7,872		$	8,074		$	6,757
	Restricted Stock
	The fair value of restricted stock awards is the market value of the stock on the date of grant. The effect of vesting conditions that apply only during the requisite service period is reflected by recognizing compensation cost only for the restricted stock awards for which the requisite service is rendered. As a result, we are required to estimate an expected forfeiture rate, as well as the probability that performance conditions that affect the vesting of certain stock-based awards will be achieved, and only recognize expense for those shares expected to vest. We estimate that forfeiture rate based on historical experience of our stock-based awards that are granted, exercised and voluntarily cancelled. If our actual forfeiture rate is materially different from our estimate, the stock-based compensation expense could be significantly different from what we have recorded in the current period. Our estimated forfeiture rate for restricted stock awards is 3.0%.
	The following table summarizes the activity of our unvested restricted stock awards under our stock plans for the year ended December 31, 2013:
		Shares		Weighted-

	Forfeited	(74,165	)	8.68
	Unvested at December 31, 2013	1,943,760		$	9.64
	The weighted-average grant date fair value of restricted stock awards granted during the years ended December 31, 2013, 2012 and 2011, was $10.98, $9.41 and $7.92, respectively. The aggregate fair value of restricted stock vested during the years ended December 31, 2013, 2012 and 2011, was $8.6 million, $8.1 million and $5.5 million, respectively. As of December 31, 2013, we had $14.4 million of unvested restricted stock, which we will record in our consolidated statements of operations over a weighted-average recognition period of approximately two years.
	Stock Options
	The fair value of stock options is estimated at the date of grant with the Black-Scholes option pricing model using various assumptions such as expected life, volatility, risk-free interest rate, dividend yield and forfeiture rates. The expected life of stock-based awards granted represents the period of time that they are expected to be outstanding and is estimated using historical data. Using the Black-Scholes option valuation model, we estimate the volatility of our common stock at the date of grant based on the historical volatility of our common stock. We base the risk-free interest rate used in the Black-Scholes option valuation model on the implied yield currently available on U.S. Treasury zero-coupon issues with an equivalent remaining term equal to the expected life of the award. We have not paid any cash dividends on our common stock, and we do not anticipate paying any cash dividends in the foreseeable future. Consequently, we used an expected dividend yield of zero in the Black-Scholes option valuation model. Finally, we use historical data to estimate pre-vesting option forfeitures. Stock-based compensation is recorded for only those awards that are expected to vest. No stock options have been issued since the year ended December 31, 2005.
	The following table summarizes the stock option activity under our stock plans for the year ended December 31, 2013:
		Options		Weighted-			Weighted-		Aggregate intrinsic

	The total intrinsic value of options exercised during the years ended December 31, 2013, 2012 and 2011 was $0.0 million, $0.0 million and $0.1 million, respectively. As of December 31, 2013, we had no remaining unvested stock options to be recorded as an expense in our consolidated statements of operations for future periods.

EARNINGS PER SHARE	'
	EARNINGS PER SHARE
	Basic and Diluted Net Income Per Share
	Basic earnings per share is computed by dividing net income available to common shareholders by the weighted-average number of common shares outstanding during the period. The weighted-average number of common shares outstanding does not include any potentially dilutive securities or any unvested restricted shares of common stock. These unvested restricted shares, although classified as issued and outstanding at December 31, 2013, 2012 and 2011 are considered contingently returnable until the restrictions lapse and will not be included in the basic earnings per share calculation until the shares are vested. Unvested shares of our restricted stock do not contain nonforfeitable rights to dividends and dividend equivalents.
	Diluted earnings per share includes the effect of all potentially dilutive securities on earnings per share. Our unvested restricted shares and stock options are potentially dilutive securities. The difference between basic and diluted weighted-average shares outstanding in 2013, 2012 and 2011 was the dilutive effect of unvested restricted shares and stock options.
	The following table represents a reconciliation of the basic and diluted earnings per share from continuing operations, or EPS, computations contained in our consolidated financial statements (in thousands):

	Some of our solutions may be subject to telecommunications excise tax and sales taxes in states and local jurisdictions where we have not collected and remitted such taxes from our customers. During the year ended December 31, 2013, we paid $0.9 million of tax and interest related to the settlement of these state excise and sales tax contingencies. No such payments were made in 2012.
	We have reserves for certain state excise and sales tax contingencies based on the likelihood of obligation. These contingencies are included in “Accrued taxes, other than income taxes” in our consolidated balance sheets. At December 31, 2013 and 2012, we had reserved $8.3 million and $2.0 million, respectively, for certain state excise and sales tax contingencies and interest. We believe we have appropriately accrued for these contingencies. In the event that actual results differ from these reserves, we may need to make adjustments, which could materially impact our financial condition and results of operations. In addition, states or local taxing authorities may disagree with our method of assessing and remitting such taxes or additional states or local taxing authorities may subject us to inquiries regarding such taxes.

FAIR VALUE MEASUREMENTS	12 Months Ended

Fair Value Disclosures [Abstract]	'
FAIR VALUE MEASUREMENTS	'
	FAIR VALUE MEASUREMENTS
	The fair value amounts for cash and equivalents, accounts receivable, net, accounts payable and accrued expenses approximate carrying amounts due to the short maturities of these instruments. The estimated fair value of our long-term debt and capital lease obligations at December 31, 2013 and 2012 was based on expected future payments discounted using current interest rates offered to us on debt of the same remaining maturity and characteristics, including credit quality, and did not vary materially from carrying value.
	Fair value is defined as an exit price representing the amount that would be received to sell an asset or paid to transfer a liability at the measurement date in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. ASC 820, “Fair Value Measurements and Disclosures,” establishes a three-tier fair value hierarchy as a basis for such assumptions which prioritizes the inputs used in measuring fair value as follows:
	•	Level 1 – Quoted prices in active markets for identical assets or liabilities;
	•	Level 2 – Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly; and
	•	Level 3 – Unobservable inputs for the asset or liability in which there is little or no market data.
	Recurring Fair Value Measurement
	During 2013, our investment in a privately-held conferencing company changed from a historical cost investment to an available-for-sale asset when that company’s shares began trading publicly on a foreign stock exchange. The fair value of this investment was based on the quoted price of our shares on that foreign exchange at the measurement date of December 31, 2013; therefore, the fair value of this investment was based on Level 1 inputs. As of December 31, 2013, the balance of this investment is included as a component of “Prepaid expenses and other current assets” on our consolidated balance sheets. As of December 31, 2012, we had no assets or liabilities that were recorded at fair value on a recurring basis.
	As further discussed in Note 12, we recorded a contingent consideration liability in connection with our Powwownow acquisition. The fair value of the liability was estimated using internal forecasts with inputs that are not observable in the market, and thus represents a Level 3 fair value measurement. The inputs in the Level 3 measurement are not supported by market activity, as they are probability assessments of expected future sales related to our acquisition of Powwownow during the earn-out period.
	We have segregated all financial assets and liabilities that are measured at fair value on a recurring basis into the most appropriate level within the fair value hierarchy based on the inputs used to determine the fair value at the measurement date in the table below (in thousands):
		31-Dec-13
		Fair Value		Level 1		Level 2		Level 3
	Current Assets:
	Available-for-sale securities	$	3,537	$	3,537	$	—	$	—

	Earn-out liability	$	3,841	$	—	$	—	$	3,841
	Total	$	3,841	$	—	$	—	$	3,841
	Non-recurring Fair Value Measurement
	We are required to record certain assets and liabilities at fair value on a non-recurring basis. Generally, assets and liabilities recorded at fair value on a non-recurring basis are the result of impairment charges.
	During the year ended December 31, 2013, we measured certain non-financial assets at fair value due to impairment made by market conditions. The following table depicts the non-recurring fair value measurements discussed below by asset category and the level within the fair value hierarchy in which the related assumptions were derived (in thousands):
		31-Dec-13
		Fair Value		Level 1		Level 2		Level 3		Total Losses

	Total	$	786	$	—	$	786	$	—	$	964
	During the year ended December 31, 2013, we wrote down one of our facilities in Europe with a carrying amount of $1.8 million, including land, building and improvements, to its fair value of $0.8 million, based on quoted prices for similar assets in the market.

ACQUISITIONS	'
	ACQUISITIONS
	In accordance with ASC Topic 805, “Business Combinations," we account for acquisitions by applying the acquisition method of accounting. The acquisition method of accounting requires, among other things, that the assets acquired and liabilities assumed in a business combination be measured at their fair values as of the closing date of the acquisition. None of our acquisitions presented below were significant individually or in the aggregate. Our 2013 acquisitions, in aggregate, contributed net revenues and net income from continuing operations of $18.6 million and $0.9 million, respectively, which are included in our consolidated statements of operations for the year ended December 31, 2013.
	Powwownow
	On December 3, 2013, we completed the acquisition of Powwownow, a U.K.-based conferencing and collaboration provider focused on small and midsize businesses, by acquiring all of Powwownow's outstanding stock. The following table summarizes the preliminary consideration paid for Powwownow (in thousands):
	Negotiated sales price	$	53,183
	Preliminary working capital and other adjustments	(618		)
	Preliminary purchase price	$	52,565
	In addition, the Powwownow purchase agreement provides for a potential earn-out payment to the sellers based on its annual revenue growth in 2014. We funded the acquisition through borrowings under our credit facility and incurred $0.4 million of direct transaction costs, which are recorded in acquisition-related costs for the year ended December 31, 2013. Powwownow's financial results since its acquisition date are included in our Europe segment.
	ACT
	On September 4, 2013, we completed the acquisition of ACT, a U.S.-based global provider of integrated conferencing solutions, by acquiring all of ACT's outstanding stock via merger. The following table summarizes the preliminary consideration paid for ACT (in thousands):
	Negotiated sales price	$	53,000
	Preliminary working capital and other adjustments	(1,515		)
	Preliminary purchase price	$	51,485
	We funded the acquisition through borrowings under our credit facility and incurred $1.4 million of direct transaction costs, which are recorded in acquisition-related costs for the year ended December 31, 2013. ACT's financial results since its acquisition date are primarily included in our North America segment, with less significant contribution included within our Europe and Asia Pacific segments.
	Preliminary Valuation of Assets and Liabilities
	The preliminary fair values of the net tangible and intangible assets acquired and liabilities assumed in connection with these acquisitions have been recognized in our consolidated balance sheets based upon their preliminary values at their respective acquisition dates, as set forth below. The excess of the purchase price over the preliminary net tangible and intangible assets was recorded as goodwill. The factors contributing to the recognition of goodwill are based on strategic and synergistic benefits that are expected to be realized from an expanded global customer base, including opportunities for us to sell our SaaS-based collaboration products to those customers, and opportunities to improve performance by leveraging best practices, operational expertise and global scale. The recognized goodwill for Powwownow and ACT are not expected to be deductible for income tax purposes. The preliminary fair values recorded were based upon preliminary valuations, and the estimates and assumptions used in such valuations are subject to change, which could be significant, within the measurement period (up to one year from each acquisition date). The primary areas of the preliminary valuations that are not yet finalized relate to amounts for income taxes including, but not limited to, current tax accounts, deferred tax accounts, amounts for uncertain tax positions and net operating loss carryforwards inclusive of associated limitations and valuation allowances, amounts for state and local excise and sales tax contingencies, the fair values of certain tangible assets and liabilities acquired, certain legal matters, the determination of identifiable intangible assets and the final amount of residual goodwill. We expect to continue to obtain information to assist us in determining the fair values of the assets acquired and liabilities assumed at each acquisition date during the measurement periods.
	The preliminary valuation of the assets acquired and liabilities assumed for Powwownow and ACT are as follows (in thousands):
				Powwownow Preliminary Valuation		ACT Preliminary Valuation
	Cash and equivalents			$	1,295	$	11,137
	Other current assets			3,221		11,447

	Total net assets			$	52,565	$	51,485
	Preliminary Valuation Adjustments for Powwownow
	We performed a preliminary valuation of the assets and liabilities of Powwownow at its acquisition date. Significant adjustments as a result of the preliminary valuation and the bases for their determination are summarized as follows:
	Indemnification asset - We recognized an indemnification asset of $8.2 million in connection with our Powwownow acquisition, which is included in "Other assets." The indemnification asset represents reimbursement we reasonably expect to receive primarily from escrow funds currently held by a financial institution pursuant to the Powwownow purchase agreement. We recorded an offsetting contingent tax liability of $8.0 million and related interest payable of $0.2 million in connection with the recognition of the indemnification asset. The tax contingency is included in “Accrued expenses” under “Long-Term Liabilities.”
	Customer relationships - Customer relationships were the primary asset acquired in the Powwownow acquisition. We valued customer relationships using the income approach, specifically the multi-period excess earnings method. The customer relationships were preliminarily valued at $29.0 million for the acquisition under this approach and will be amortized over ten years.
	Non-compete agreements - We valued non-compete agreements using the income approach, specifically based on the negative impact on the business that the individuals could have on revenue. The non-compete agreements were valued at $2.1 million for the Powwownow acquisition under this approach and will be amortized over three years.
	Trade names - We valued trade names using the income approach, specifically the multi-period excess earnings method. In determining the fair value of the trade names, the multi-period excess earnings approach values the intangible asset at the present value of the incremental after-tax cash flows attributable only to the trade names after applying a royalty rate to the overall revenues. The trade names were valued at $4.4 million for the Powwownow acquisition under this approach and will be amortized over ten years.
	Earn-out - We recorded a contingent consideration liability of approximately $3.8 million as of the acquisition date related to the Powwownow earn-out, included in “Accrued expenses” under “Long-Term Liabilities” in our consolidated balance sheets. The fair value of the liability was estimated using internal forecasts with inputs that are not observable in the market, and thus represents a Level 3 fair value measurement, as defined in Note 11. The inputs in the Level 3 measurement are not supported by market activity, as they are probability assessments of expected future sales related to our acquisition of Powwownow during the earn-out period. The earn-out will be re-measured quarterly, with the change being reflected as acquisition-related costs in our consolidated statements of operations. See Note 11 for additional information.
	Deferred tax liabilities, net - $6.1 million was recorded to adjust deferred taxes for the preliminary fair value adjustments made in accounting for our Powwownow acquisition.
	Preliminary Valuation Adjustments for ACT
	We performed a preliminary valuation of the assets and liabilities of ACT at its acquisition date. Significant adjustments as a result of the preliminary valuation and the bases for their determination are summarized as follows:
	Indemnification asset - We recognized an indemnification asset of $4.1 million in connection with our ACT acquisition. Of this amount, $1.1 million is included in "Other current assets" and $3.0 million is included in "Other assets." The indemnification asset represents reimbursement we reasonably expect to receive from escrow funds currently held by a financial institution pursuant to the ACT merger agreement. We recorded an offsetting uncertain tax position of $3.8 million and related interest payable of $0.3 million in connection with the recognition of the indemnification asset. The income tax contingency is included above in “Long-Term Liabilities.”
	Customer relationships - Customer relationships were the primary asset acquired in the ACT acquisition. We valued customer relationships using the income approach, specifically the multi-period excess earnings method. In determining the fair value of the customer relationships, the multi-period excess earnings approach values the intangible asset at the present value of the incremental after-tax cash flows attributable only to the customer relationship after deducting the contributory asset charges. The customer relationships were preliminarily valued at $30.2 million for the acquisition under this approach and will be amortized over ten years. This total includes an adjustment from the initial preliminary valuation date of $1.3 million for updates in assumptions including discount rate.
	Non-compete agreements - We valued non-compete agreements using the income approach, specifically based on the negative impact on the business that the individuals could have on revenue. The non-compete agreements were valued at $0.8 million for the ACT acquisition under this approach and will be amortized over five years.
	Deferred tax liabilities, net - $10.7 million was recorded to adjust deferred taxes for the preliminary fair value adjustments made in accounting for our ACT acquisition. This includes an adjustment from the initial preliminary valuation date of $5.3 million.
	Powwownow and ACT Preliminary Pre-Acquisition Contingencies Assumed
	We have evaluated and continue to evaluate pre-acquisition contingencies relating to Powwownow and ACT that existed as of each acquisition date. Based on our evaluation to date, we have preliminarily determined that certain pre-acquisition contingencies are probable in nature and estimable as of each acquisition date. Accordingly, we have recorded our best estimates for these contingencies as part of the preliminary valuation of the assets and liabilities acquired. We continue to gather information relating to all pre-acquisition contingencies that we have assumed. Any changes to the pre-acquisition contingency amounts recorded during the measurement period will be included in the final valuation and related amounts recognized. Subsequent to the end of the measurement period, any adjustments to pre-acquisition contingency amounts will be reflected in our results of operations.
	Copper
	On August 1, 2013, we acquired substantially all of the assets and assumed certain liabilities of the conferencing services business of Copper, a U.S.-based audio and web conferencing services provider, for $10.3 million, including a $0.2 million working capital adjustment finalized in December 2013. We funded the acquisition through borrowings under our credit facility and incurred $0.4 million of direct transaction costs, which are recorded in acquisition-related costs for the year ended December 31, 2013.
	Copper's financial results since its acquisition date are included in our North America segment. The primary assets acquired as part of the Copper acquisition were customer relationships totaling $6.4 million and goodwill of $3.3 million. The recognized goodwill for Copper is expected to be deductible for income tax purposes.

	Operating Lease Commitments
	We lease office space, computer and other equipment and automobiles under noncancelable lease agreements. The leases generally provide that we pay the taxes, insurance and maintenance expenses related to the leased assets. Future minimum lease payments for noncancelable operating leases as of December 31, 2013 are as follows (in thousands):
		2014	$	18,990
		2015	14,864

		2017	10,922
		2018	8,924
		Thereafter	10,424
		Net minimum lease payments	$	76,485
	Included in our future minimum lease payments is an aggregate of $0.3 million for leases included in our restructuring efforts. Rent expense under operating leases was $11.9 million, $11.1 million and $11.4 million for the years ended December 31, 2013, 2012 and 2011, respectively. In 2013, 2012 and 2011 facilities rent was reduced by approximately $0.5 million, $1.2 million and $1.6 million, respectively, associated with contractual obligations provided for in the restructuring charge.
	Asset Retirement Obligation
	Our recorded asset retirement obligation liability represents the estimated costs to bring certain office buildings that we lease back to their original condition after the termination of the lease. In instances where our lease agreements either contain make-whole provision clauses or subject us to remediation costs, we establish an asset retirement obligation liability with a corresponding increase to leasehold improvements. These amounts are included in “Accrued expenses” under “Long-Term Liabilities” and “Current Liabilities” in our consolidated balance sheets. There was no significant change in asset retirement obligation liabilities during 2013. Our asset retirement obligation liability balance was $1.2 million at December 31, 2013 and 2012.
	Supply Agreements
	We purchase voice and data services pursuant to supply agreements with telecommunications service providers. Agreements with some of our telecommunications service providers contain minimum purchase requirements totaling approximately $9.1 million, $1.3 million and $0.7 million for 2014, 2015 and 2016, respectively. Our total minimum purchase requirements were approximately $7.4 million, $28.5 million and $51.0 million in 2013, 2012 and 2011, respectively, of which we incurred costs in excess of these minimums.
	Litigation and Claims
	In connection with the sale of our PGiSend messaging business in October 2010, we agreed to indemnify the purchaser, EasyLink (subsequently acquired by OpenText), for the tax-related matters described below. We have accrued an estimated loss for these matters totaling an aggregate of approximately $3.9 million. The possible loss or range of loss resulting from these matters, if any, in excess of the amounts accrued is inherently unpredictable and involves significant uncertainty and negotiations over an extended time period. Consequently, no estimate can be made of any possible loss or range of loss in excess of the above-mentioned accrual.
	State Telecommunications Excise Tax Matters
	On March 19, 2013, we received notice of deficiencies from the New York State Department of Taxation and Finance, dated March 15, 2013, for telecommunications franchise and gross excise taxes assessed on our former subsidiary, Xpedite, for the tax years ended December 31, 2001 - 2006. The assessments totaled approximately $4.3 million as of March 4, 2013, including approximately $1.9 million in taxes and $2.4 million in accrued interest and penalties, on which interest continues to accrue. We believe we are adequately reserved for this matter. We plan to vigorously contest these assessments. However, if the New York State Department of Taxation’s assessment is sustained, the amount assessed could result in a material adjustment to our consolidated financial statements which would impact our cash flows and results of operations. We agreed to indemnify EasyLink for this matter in connection with our PGiSend sale.
	State Corporate Tax Matter
	On August 6, 2010, our former subsidiary, Xpedite, received a final determination from the New Jersey Division of Taxation upholding a corporate business tax audit assessment for the tax years ended December 31, 1998 through December 31, 2000 and December 31, 2002. The assessment totaled approximately $6.2 million as of August 15, 2010, including approximately $2.4 million in taxes and $3.8 million in accrued interest and penalties, which interest continues to accrue. The assessment relates to the sourcing of Xpedite’s receipts for purposes of determining the amount of its income that is properly attributable to, and therefore taxable by, New Jersey. We are vigorously contesting the determination, filed a timely appeal with the Tax Court of New Jersey on November 2, 2010 and continue to engage in settlement negotiations. We believe we are adequately reserved for this matter. However, if the New Jersey Division of Taxation’s final determination is sustained, the amount assessed could result in a material adjustment to our consolidated financial statements which would impact our financial condition and results of operations. We agreed to indemnify EasyLink for this matter in connection with our PGiSend sale.
	Other Litigation and Claims
	We are involved in other litigation matters and are subject to claims that we do not believe will have a material adverse effect upon our business, financial condition or results of operations, although we can offer no assurance as to the ultimate outcome of any such matters.

	At December 31, 2013, we had federal income tax net operating loss carryforwards of approximately $13.5 million, which will expire in 2018. The utilization of some of our net operating losses is subject to Internal Revenue Code of 1986, as amended, Section 382 limitations related to one of our previous acquisitions. We had federal capital loss carryforwards of approximately $42.6 million expiring in 2014 and 2015. We had foreign income tax net operating loss carryforwards of approximately $23.7 million, some of which have expiration years beginning in 2015 and some of which are unlimited. We also had tax credit carryforwards of approximately $35.4 million with expiration dates between 2018 and 2033. If certain substantial changes to our ownership occur, there could be additional annual limitations on the amount of the carryforwards that can be utilized.
	The undistributed earnings of our foreign subsidiaries are not subject to U.S. federal and state income taxes unless such earnings are distributed in the form of dividends or otherwise to the extent of current and accumulated earnings and profits. Upon distribution, we would be subject to both U.S. income taxes, net of foreign tax credits, and withholding taxes payable to the various foreign countries. The undistributed earnings of our foreign subsidiaries are permanently reinvested to the extent the earnings cannot be distributed free of U.S. income taxes or are not subject to a loan or note payable by the foreign subsidiary to a U.S. affiliate. The undistributed earnings of our foreign subsidiaries that are considered permanently reinvested and have not been remitted to the United States totaled $44.8 million and $34.4 million as of December 31, 2013 and 2012, respectively. We made the determination of permanent reinvestment on the basis of sufficient evidence that demonstrates that we will invest the undistributed earnings overseas indefinitely for use in working capital, as well as foreign acquisitions and expansion. The determination of the amount of the unrecognized deferred U.S. income tax liability related to the undistributed earnings is not practicable; however, unrecognized foreign income tax credits would be available to reduce a portion of this liability.
	A reconciliation of unrecognized tax benefits at the beginning and end of the years presented is as follows (in thousands):
		2013			2012			2011
	Balance at January 1,	$	5,410		$	3,447		$	3,719
	Additions for tax positions for the current year	455			1,749			91

Expiration of the statute of limitations	(1,000		)	(572		)	(119		)
Balance at December 31,	$	9,422		$	5,410		$	3,447
Upon resolution, unrecognized tax benefits of $7.7 million and $4.1 million as of December 31, 2013 and 2012, respectively, would affect our annual effective tax rate. The unrecognized tax benefits at December 31, 2013 are included in “Other assets,” and “Accrued expenses” under “Long-Term Liabilities” in our consolidated balance sheets. As of December 31, 2013, we anticipate that approximately $0.9 million of unrecognized tax benefits associated with certain state and local income taxes will be settled over the next 12 months. In addition, we anticipate that the statute of limitations will expire over the next 12 months for approximately $1.7 million of unrecognized tax benefits associated with foreign reorganizations that occurred during pre-acquisition periods for certain acquired legal entities.
We recognize interest and penalties related to uncertain tax positions in “Interest expense” and “Operating expenses,” respectively, in our consolidated statements of operations. During the years ended December 31, 2013, 2012 and 2011, we recognized interest and penalties expense of $0.5 million, $0.3 million, and $0.8 million, respectively. As of December 31, 2013 and 2012, we had accrued interest and penalties of approximately $3.7 million and $2.7 million, respectively, related to uncertain tax positions. As interest and penalties are classified as “Interest expense” and “Operating expenses,” respectively, the accrual or recognition of interest and penalties from the associated uncertain tax positions will not affect our annual effective tax rate.
In the normal course of business, we are subject to inquiries and routine income tax audits from U.S. and non-U.S. tax authorities with respect to income taxes. In major tax jurisdictions, tax years 2001 to 2013 remain subject to income tax examinations by tax authorities. These inquiries may result in adjustments to the timing or amount of taxable income and deductions or the allocation of income among tax jurisdictions.
An analysis of our deferred tax asset valuation allowances is as follows (in thousands):
Balance as of December 31, 2010,	$	33,665
Additions	—
Deductions	(9,520		)
Balance as of December 31, 2011,	24,145

Additions	6,322
Deductions	(3,796		)
Balance at December 31, 2013	$	29,087
Our valuation allowance at December 31, 2013 primarily relates to certain federal, state and foreign net operating loss and capital loss carryforwards that, in the opinion of management, are more likely than not to expire unutilized. During the year ended December 31, 2013, our valuation allowance increased by approximately $6.3 million primarily as a result of net operating losses from certain legal entities acquired during 2013 and decreased approximately $3.8 million primarily as a result of 2013 changes to the apportionment factors of certain U.S. state jurisdictions and the write-off of certain federal net operating losses due to statutorily determined limitations.
During the year ended December 31, 2012, our valuation allowance increased by approximately $2.4 million primarily as a result of a change in purchase price allocation that affected capital loss carryforwards related to our PGiSend sale.
During the year ended December 31, 2011, our valuation allowance decreased by approximately $9.5 million, primarily as a result of an increase in the valuation reserves placed on the capital loss carryforwards related to our PGiSend sale.

	SEGMENT REPORTING
	We manage our operations on a geographic regional basis, with segments in North America, Europe and Asia Pacific. The accounting policies as described in the summary of significant accounting policies are applied consistently across our segments. Our North America segment is primarily comprised of operations in the United States and Canada. We present “Operating income” for each of our segments as a measure of segment profit. Our chief operating decision makers use operating income internally as a means of analyzing segment performance and believe that it more clearly represents our segment profit without the impact of income taxes and other non-operating items.
	The sum of these regional results may not agree to the consolidated results due to rounding. Information concerning our continuing operations in our segments is as follows (in thousands):

SIGNIFICANT ACCOUNTING POLICIES (Policy)	12 Months Ended
	Dec. 31, 2013
Accounting Policies [Abstract]	'
Accounting Estimates	'
	Accounting Estimates
	Preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and reported amounts of net revenues and expenses during the reporting period. Financial statement line items that include significant estimates consist of goodwill, net intangibles, accrued restructuring costs, certain tax accounts, certain accrued liabilities and the allowance for uncollectible accounts receivable. Changes in the facts or circumstances underlying these estimates could result in material changes, and actual results could differ from those estimates. These changes in estimates are recognized in the period they are realized.
Principles of Consolidation and Basis of Presentation	'
	Principles of Consolidation and Basis of Presentation
	The financial statements include our accounts consolidated with our wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. Unless otherwise stated, current and prior period results in our consolidated statements of operations and cash flows and these notes reflect our results from continuing operations and exclude the effect of current and prior period discontinued operations. See Note 4 to our consolidated financial statements for additional information and related disclosures regarding our discontinued operations. Certain prior year amounts have been reclassified to conform to current year presentation.
Cash and Equivalents and Restricted Cash	'
	Cash and Equivalents and Restricted Cash
	Cash and equivalents consist of cash on hand. Cash balances that are legally restricted as to usage or withdrawal are separately included in “Prepaid expenses and other current assets” on our consolidated balance sheets. At December 31, 2013 and 2012, we had $0.0 million and $0.6 million of restricted cash, respectively.
Accounts Receivable and Allowance for Doubtful Accounts	'
	Accounts Receivable and Allowance for Doubtful Accounts
	Included in accounts receivable at December 31, 2013 and 2012 was earned but unbilled revenue of approximately $5.7 million and $6.7 million, respectively, which results from non-calendar month billing cycles and the one-month lag in billing of certain of our services. Earned but unbilled revenue is billed within 30 days. Provision for doubtful accounts was approximately $0.5 million, $1.1 million and $0.6 million in 2013, 2012 and 2011, respectively. Write-offs against the allowance for doubtful accounts were $0.6 million, $0.9 million and $0.9 million in 2013, 2012 and 2011, respectively. Our allowance for doubtful accounts represents reserves for receivables that reduce accounts receivable to amounts expected to be collected. The allowance for doubtful accounts was approximately $0.8 million, $0.8 million and $0.6 million as of December 31, 2013, 2012 and 2011, respectively. Management uses significant judgment in estimating uncollectible amounts. In estimating uncollectible amounts, management considers factors such as historical and anticipated customer payment performance and industry-specific economic conditions. Using these factors, management assigns reserves for uncollectible amounts by accounts receivable aging categories to specific customer accounts.
Property and Equipment	'
	Property and Equipment
	Property and equipment are recorded at cost. Depreciation is recorded under the straight-line method over the estimated useful lives of the assets, commencing when the assets are placed in service. The estimated useful lives are five to seven years for furniture and fixtures, two to five years for software and three to five years for computer servers and Internet and telecommunications equipment. The cost of installation of equipment is capitalized, as applicable. Amortization of assets recorded under capital leases is included in depreciation. Assets recorded under capital leases and leasehold improvements are depreciated over the shorter of their useful lives or the term of the related lease.
Research and Development	'
	Research and Development
	Research and development expenses primarily related to developing new services, features and enhancements to existing services that do not qualify for capitalization are expensed as incurred.
Software Development Costs	'
	Software Development Costs
	We capitalize certain costs incurred to develop software features used as part of our service offerings within “Property and Equipment, Net” on our consolidated balance sheets. For the years ended December 31, 2013, 2012 and 2011, we capitalized approximately $17.5 million, $15.3 million and $15.3 million, respectively, of these costs. We amortize these capitalized costs on a straight-line basis over the estimated life of the related software, not to exceed five years. Depreciation expense recorded for developed software for the years ended December 31, 2013, 2012 and 2011, was approximately $13.7 million, $12.1 million and $10.2 million, respectively.
Goodwill	'
	Goodwill
	Goodwill is subject to an impairment assessment performed at the reporting unit level, at least annually and more frequently if indicators of impairment are identified. Our reporting units are our operating segments, North America, Europe and Asia Pacific. We utilize December 31 as our annual date to perform the assessment and adopted the qualitative goodwill impairment assessment standard, applied as of December 31, 2012. Under this standard, management evaluates whether it is more likely than not that the carrying value of a reporting unit exceeds its fair value. Factors utilized in this qualitative assessment include the results of the most recent impairment test, economic factors impacting the conferencing and collaboration industry, current and long-range forecasted financial results and changes in the strategic outlook of the reporting unit. If it is determined that fair value more likely than not exceeds carrying value, then goodwill is not considered impaired and no quantitative impairment test is required for that reporting unit. If it is more likely than not that carrying value exceeds fair value, we proceed with the quantitative two-step impairment assessment. The first step is to identify potential goodwill impairment by comparing the calculated estimated fair value of the reporting unit to its carrying amount. The second step measures the amount of the impairment based upon a comparison of “implied fair value” of goodwill with its carrying amount.
	As a result of the acquisitions made in 2013, we elected to perform step one of the quantitative impairment test for each of our reporting units for our December 31, 2013 assessment. Based on our quantitative assessment this year, the estimated fair value of our Europe and Asia Pacific reporting units substantially exceeded their respective carrying values, while the estimated fair value of our North America segment exceeded its carrying value by 20%. No impairment of goodwill was identified in any of the years ended December 31, 2013, 2012 and 2011.
Valuation of Long-Lived Assets	'
	Valuation of Long-Lived Assets
	We evaluate the carrying values of long-lived assets when significant adverse changes in the economic value of these assets require an analysis, including property and equipment and other intangible assets. A long-lived asset is considered impaired when its fair value is less than its carrying value. In that event, a loss is calculated based on the amount the carrying value exceeds the future cash flows, as calculated under the best-estimate approach, of such asset. We believe that long-lived assets in our consolidated balance sheets are appropriately valued. Asset impairments were $1.2 million, $0.9 million and $0.5 million during 2013, 2012 and 2011, respectively, and are recognized as “Asset impairments” in our consolidated statements of operations.
Investments	'
	Investments
	In March 2013, we invested $1.0 million in a privately-held cloud solutions provider. In September 2012, we invested $1.0 million in a privately-held cloud service marketplace company by purchasing a convertible promissory note, which was repaid to us in January 2014 for the principal balance plus accrued interest at an annual rate of 8%.
	These investments are accounted for under the cost method and are periodically assessed for other-than-temporary impairment using financial results, economic data and other quantitative and qualitative factors deemed applicable. In the event an other-than-temporary impairment occurs, an impairment loss equal to the difference between the cost basis and the fair value will be recognized. After the effects of foreign currency exchange rate fluctuations and accrued interest, our cost method investments had a total carrying value of $2.1 million and $1.9 million as of December 31, 2013 and 2012, respectively. These amounts were included as a component of “Other assets” on our consolidated balance sheets for each period presented, except for the convertible promissory note, which was included as a component of “Prepaid expenses and other current assets” as of December 31, 2013.
	In June 2011, we invested approximately $1.0 million in a privately-held conferencing company. During December 2013, this investment changed from a historical cost investment to an available-for-sale asset when that company’s shares began trading publicly on a foreign stock exchange. The fair value of this investment was based on the quoted price of our shares on that foreign exchange at the measurement date of December 31, 2013. This investment is also subject to fluctuations in foreign currency exchange rates. Any related gains or losses related to the market value of the shares or fluctuations in foreign currency are excluded from earnings until realized and reported as a component of “Accumulated other comprehensive gain” on our consolidated balance sheets. After the effects of foreign currency exchange rate fluctuations and adjustments to the quoted market value, the available-for-sale investment had a market value of $3.5 million, which was included as a component of “Prepaid expenses and other current assets” as of December 31, 2013.
Revenue Recognition	'
	Revenue Recognition
	We recognize revenues when persuasive evidence of an arrangement exists, services have been rendered, the price to the buyer is fixed or determinable and collectability is reasonably assured. Revenues from continuing operations consist primarily of usage fees generally based on per minute, and prior to our discontinued reclassifications, per fax page or per transaction methods. To a lesser extent, we charge subscription-based and license fees and have fixed-period minimum revenue commitments related to our SaaS-based collaboration products. These subscription-based fees are considered service arrangements per the authoritative guidance; accordingly, fees related to subscription agreements are recognized ratably over the contract term, which is typically 12 to 24 months. We also include per minute usage fees generated through the use of our SaaS-based collaboration products in SaaS revenues. These usage fees, which are generated if a customer elects to use either minutes in excess of the contractual amount or of a type not included in the arrangement, are recognized as incurred by the customer, consistent with our other per minute usage fees. In addition, SaaS revenues may also include set-up fees, which are recognized ratably over the contract term or the expected customer life, whichever is longer. Unbilled revenue consists of earned but unbilled revenue that results from non-calendar month billing cycles and the one-month lag time in billing related to certain of our services. Deferred revenue consists of payments made by customers in advance of the time services are rendered. Incremental direct costs incurred related to deferred revenue are deferred over the life of the contract and are recorded in “Prepaid expenses and other current assets” in our consolidated balance sheets.
USF Charges	'
	USF Charges
	In accordance with FCC rules, we are required to contribute to the federal USF for some of our solutions, which we recover from our applicable customers and remit to the USAC. We present the USF charges that we collect and remit on a net basis, with both collections from our customers and the amounts we remit, recorded in "Net revenues". Had we presented USF charges on a gross basis, net revenues and cost of revenues would have been $27.1 million, $32.0 million and $30.4 million higher for the years ended December 31, 2013, 2012 and 2011, respectively.
Foreign Currency Translation	'
	Foreign Currency Translation
	The assets and liabilities of subsidiaries with a functional currency other than the U.S. Dollar are translated at rates of exchange existing at our consolidated balance sheet dates. Revenues and expenses are translated at average rates of exchange prevailing during the year. The resulting translation adjustments are recorded in the “Accumulated other comprehensive gain” component of shareholders’ equity. In addition, certain of our intercompany loans with foreign subsidiaries are considered to be permanently invested for the foreseeable future. Therefore, foreign currency exchange gains and losses related to these permanently invested balances are recorded in the “Accumulated other comprehensive gain” component of shareholders’ equity in our consolidated balance sheets.
Treasury Stock	'
	Treasury Stock
	All treasury stock transactions are recorded at cost, and all shares of treasury stock repurchased are retired. During the year ended December 31, 2013, we repurchased approximately 0.1 million shares of our common stock in the open market for approximately $1.4 million at an average price of $10.54 per share. During the year ended December 31, 2012, we repurchased approximately 3.2 million shares of our common stock in the open market for approximately $27.9 million at an average price of $8.81 per share.
	During the years ended December 31, 2013 and 2012, we redeemed 215,387 and 246,735 shares, respectively, of our common stock to satisfy certain of our employees’ tax withholdings due upon the vesting of their restricted stock grants and remitted approximately $2.7 million and $2.0 million, respectively, in taxes on our employees’ behalf.
Preferred Stock	'
	Preferred Stock
	We have 5.0 million shares of authorized $0.01 par value preferred stock, none of which are issued or outstanding. Under the terms of our amended and restated articles of incorporation, our board of directors is empowered to issue preferred stock without shareholder action.
Income Taxes	'
	Income Taxes
	Income taxes are determined under the asset and liability method as required by ASC 740, “Income Taxes”. Under this method, deferred tax assets and liabilities are recognized based upon the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary items are expected to be recovered or settled. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts more likely than not to be realized. To the extent we establish a valuation allowance or increase this allowance in a period, an expense is recorded within the income tax provision in our consolidated statements of operations. Under current accounting principles, the impact of an uncertain income tax position on the income tax return must be recognized at the largest amount that is more likely than not to be sustained upon audit by the relevant taxing authority. Accrued interest related to uncertain tax positions is recorded as "Interest expense" in our consolidated statements of operations. See Note 16 to our consolidated financial statements for additional information and related disclosures regarding our income taxes.
Restructuring Costs	'
	Restructuring Costs
	Restructuring reserves are based on certain estimates and judgments related to severance and exit costs, contractual obligations and related costs and are recorded as “Restructuring costs” in our consolidated statements of operations. See Note 3 to our consolidated financial statements for additional information and related disclosures regarding our restructuring costs.
Acquisition-related Costs	'
	Acquisition-related Costs
	Acquisition-related costs reflected in our consolidated statements of operations include, but are not limited to, transaction costs such as banking, legal, accounting and other professional fees directly related to acquisitions, termination and related costs for transitional and certain other employees, integration-related professional fees and other post-business combination expenses associated with our business acquisitions.
	The following table summarizes acquisition-related costs incurred during the year ended December 31, 2013 (in thousands):
		2013
	Professional fees	$	2,439
	Release of indemnification asset	1,129
	Integration-related costs	1,824
	Total acquisition-related costs	$	5,392
	For further discussion of the indemnification asset and related costs see Notes 12 and 16 to our consolidated financial statements.
Advertising Costs	'
	Advertising Costs
	We expense production costs associated with an advertisement the first time the advertising takes place. All other advertising-related costs are expensed as incurred. We expense advertising costs as advertising space or airtime is used. Total advertising expense in 2013, 2012 and 2011 was $6.1 million, $8.9 million and $16.9 million, respectively. As of December 31, 2013 and 2012, we had $0.0 million and $0.3 million of prepaid advertising, respectively.
Legal Contingencies	'
	Legal Contingencies
	We are involved from time to time in certain legal matters and subject to other claims as disclosed in Note 14 to our consolidated financial statements. We accrue an estimate for legal contingencies when we determine that it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. These estimates are developed in consultation with outside counsel handling these matters and based upon an analysis of potential results, assuming a combination of litigation and settlement strategies.
New and Recently Adopted Accounting Pronouncements	'
	New and Recently Adopted Accounting Pronouncements
	In July 2013, the FASB issued ASU No. 2013-11, “Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists,” which requires an unrecognized tax benefit to be presented as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss or a tax credit carryforward that the entity intends to use and is available for settlement at the reporting date. This guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. As the guidance is consistent with our current reporting practices, it will not have a material impact on our consolidated financial position or results of operations.
