BASIS OF PRESENTATION	'
	BASIS OF PRESENTATION
	Premiere Global Services, Inc., or PGi, has been a global leader in collaboration and virtual meetings for over 20 years. Our cloud-based solutions deliver multi-point, real-time virtual collaboration using video, voice, mobile, web streaming and file sharing technologies. PGi solutions are available via desktops, tablets and mobile devices, helping businesses worldwide be more productive, mobile and environmentally responsible. We have a global presence in 25 countries in our three segments in North America, Europe and Asia Pacific.
	Our unaudited condensed consolidated financial statements and related footnotes have been prepared in accordance with U.S. generally accepted accounting principles, or GAAP, for interim financial information and Rule 10-01 of Regulation S-X issued by the Securities and Exchange Commission, or SEC. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. We believe that these condensed consolidated financial statements include all adjustments (consisting only of normal recurring adjustments) necessary to fairly present the results for interim periods shown. All significant intercompany accounts and transactions have been eliminated in consolidation. Our results of operations for the three and nine months ended September 30, 2013 are not indicative of the results that may be expected for the full fiscal year of 2013 or for any other interim period. The financial information presented herein should be read in conjunction with our annual report on Form 10-K for the year ended December 31, 2012, which includes information and disclosures not included in this quarterly report.
	Unless otherwise stated, current and prior period results in our condensed consolidated statements of operations and cash flows and these notes reflect our results from continuing operations and exclude the effect of discontinued operations. See Note 4 to our condensed consolidated financial statements for additional information and related disclosures regarding our discontinued operations.

SIGNIFICANT_ACCOUNTING_POLICIE

SIGNIFICANT ACCOUNTING POLICIES	9 Months Ended
	Sep. 30, 2013
Accounting Policies [Abstract]	'
SIGNIFICANT ACCOUNTING POLICIES	'
	SIGNIFICANT ACCOUNTING POLICIES
	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 condensed consolidated balance sheets. At September 30, 2013 and December 31, 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 September 30, 2013 and December 31, 2012 was earned but unbilled revenue of $8.7 million and $6.7 million, respectively, which results from non-calendar month billing cycles and the one-month lag time in billing related to certain of our services. Earned but unbilled revenue is billed within 30 days. Due to the recovery of an amount previously written off, there was a benefit to the provision for doubtful accounts of ($0.1) million for the three months ended September 30, 2013, while the provision for doubtful accounts was $0.3 million for the three months ended September 30, 2012. Provision for doubtful accounts was $0.2 million and $0.8 million for the nine months ended September 30, 2013 and 2012, respectively. (Recoveries) write-offs against the allowance for doubtful accounts were ($0.1) million and $0.3 million in the three months ended September 30, 2013 and 2012, respectively. Write-offs against the allowance for doubtful accounts were $0.3 million and $0.7 million for the nine months ended September 30, 2013 and 2012, respectively. Our allowance for doubtful accounts represents reserves for receivables that reduce accounts receivable to amounts expected to be collected. 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 ten years for computer servers and Internet and telecommunications equipment. Accumulated depreciation was $152.8 million and $134.2 million as of September 30, 2013 and December 31, 2012, respectively. 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 condensed consolidated balance sheets. We capitalized approximately $4.8 million and $3.6 million of these costs for the three months ended September 30, 2013 and 2012, respectively, and $13.1 million and $11.2 million of these costs for the nine months ended September 30, 2013 and 2012, respectively. 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 the developed software was $3.5 million and $3.2 million for the three months ended September 30, 2013 and 2012, respectively, and $10.0 million and $9.0 million for the nine months ended September 30, 2013 and 2012, 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. No impairment of goodwill was identified in the year ended December 31, 2012, the date of our most recent assessment. As of September 30, 2013, we are not aware of any events that would lead to an impairment; therefore, we do not believe that any of our reporting units are at risk of failing step one of the goodwill impairment test.
	Cost Method 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. We earn interest on this investment at an annual rate of 8% that will be due with the principal balance in September 2014. In June 2011, we invested approximately $1.0 million in a privately-held conferencing company. This investment is subject to fluctuations in foreign currency exchange rates.
	These three 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 would be recognized. After the effects of foreign currency exchange rate fluctuations, our cost method investments had a total carrying value of $2.9 million and $1.9 million as of September 30, 2013 and December 31, 2012, respectively. These amounts were included as a component of “Other assets” on our condensed 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 September 30, 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 which are generally billed on a per minute basis. To a lesser extent, we charge subscription-based and license fees and have fixed-period minimum revenue commitments. Revenues related to our virtual meeting solutions primarily consist of usage fees which are recognized ratably over the contracted term of the agreement. These revenues may also include set-up fees and maintenance and update fees, which are typically also recognized ratably over the life of the contract. 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 condensed consolidated balance sheets.
	USF Charges
	In accordance with Federal Communications Commission rules, we are required to contribute to the federal Universal Service Fund, or USF, for some of our solutions, which we recover from our applicable customers and remit to the Universal Service Administration Company. 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 $6.5 million and $7.4 million higher for the three months ended September 30, 2013 and 2012, respectively, and $20.9 million and $24.4 million higher for the nine months ended September 30, 2013 and 2012, 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 condensed 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 income” 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 income” component of shareholders’ equity in our condensed consolidated balance sheets.
	Treasury Stock
	All treasury stock transactions are recorded at cost, and all shares of treasury stock repurchased are retired. During the nine months ended September 30, 2013, we repurchased 16,000 shares of our common stock for $0.2 million in the open market at an average price of $10.52 per share pursuant to our board-approved stock repurchase program. During the nine months ended September 30, 2012, we repurchased 1,990,843 shares of our common stock for $17.7 million in the open market at an average price of $8.88 per share pursuant to our board-approved stock repurchase program.
	During the nine months ended September 30, 2013 and 2012, we redeemed 147,142 and 192,883 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 $1.9 million and $1.7 million, respectively, to the Internal Revenue Service 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.
	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 condensed consolidated statements of operations. See Note 3 to our condensed consolidated financial statements for additional information and related disclosures regarding our restructuring costs.
	Acquisition-related Costs
	Acquisition-related costs reflected in our condensed 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 acquisitions.
	The following table summarizes acquisition-related costs incurred during the three and nine months ended September 30, 2013:
		Three Months Ended September 30, 2013		Nine Months Ended September 30, 2013
	Professional fees	$	1,287	$	1,287
	Release of indemnification asset	1,129		1,129
	Integration-related costs	389		628
	Total acquisition-related costs	$	2,805	$	3,044
	For further discussion of the indemnification asset and related costs see Note 12 to our condensed consolidated financial statements and "-Income Taxes" below.
	Excise and Sales Tax
	Some of our solutions may be subject to telecommunications excise tax and sales taxes in states where we have not collected and remitted such taxes from our customers. During the nine months ended September 30, 2013, we made payments of $0.7 million in partial satisfaction of anticipated amounts due to certain states. In 2012, we did not make any significant payments related to the settlement of these state excise and sales tax contingencies.
	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 condensed consolidated balance sheets. At September 30, 2013 and December 31, 2012, we had reserved approximately $6.0 million and $2.0 million, respectively, for certain state excise and sales tax contingencies and interest. The increase in this reserve is primarily related to our acquisition of ACT Teleconferencing Inc., or ACT. We believe we have appropriately accrued for these contingencies. In the event that actual results differ from these reserves, or new information becomes available, we may need to make adjustments, which could materially impact our financial condition and results of operations. In addition, states may disagree with our method of assessing and remitting such taxes, or additional states may subject us to inquiries regarding such taxes.
	Income Taxes
	Income taxes are determined under the asset and liability method as required by Accounting Standards Codification, or 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 condensed 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.
	Income tax expense for the three and nine months ended September 30, 2013 was $2.1 million and $6.8 million, respectively, compared to $0.9 million and $6.6 million, respectively, for the three and nine months ended September 30, 2012. The increase in income tax expense during the three and nine months ended September 30, 2013 compared to the same periods in the prior year is related to discrete tax benefits in 2012 not present in 2013. Income tax expense for both the three and nine months ended September 30, 2013 includes a $1.0 million benefit due to the release of certain unrecognized tax benefits recorded in connection with our ACT acquisition. This amount was offset by expense associated with the reversal of the related tax indemnification asset which was recorded in acquisition-related costs.
	As of September 30, 2013 and December 31, 2012, we had $9.0 million and $5.4 million, respectively, of unrecognized tax benefits. The increase in this amount is primarily related to our ACT acquisition. Upon resolution, unrecognized tax benefits of $7.5 million and $4.1 million as of September 30, 2013 and December 31, 2012, respectively, would affect our annual effective tax rate. The unrecognized tax benefits are included in “Accrued expenses” under “Long-Term Liabilities” in our condensed consolidated balance sheets.
	Our valuation allowance at December 31, 2012 primarily relates to certain foreign and state net operating loss and capital loss carryforwards that, in the opinion of management, are more likely than not to expire unutilized. During the nine months ended September 30, 2013, our valuation allowance increased by $0.2 million primarily as a result of current year tax losses in certain foreign jurisdictions that, in the opinion of management, are more likely than not to go unutilized.
	Fair Value Measurements
	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. The fair value amounts for cash and equivalents, accounts receivable, net, and 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 September 30, 2013 and December 31, 2012 were 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.
	New and Recently Adopted Accounting Pronouncements
	In July 2013, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update, or 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 condensed 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 nine months ended September 30, 2013. The expenses associated with these activities are reflected in “Restructuring costs” in our condensed consolidated statements of operations. Cash payments for restructuring costs from continuing operations were $1.2 million and $1.9 million during the nine months ended September 30, 2013 and 2012, respectively. The components included in the reconciliation of the liability balances include costs related to our continuing and discontinued operations (in thousands):
		Balance at		Provisions		Cash Payments			Non-cash			Balance at
		31-Dec-12										30-Sep-13
	Accrued restructuring costs:

	Total restructuring costs	$	1,156	$	441	$	(1,158	)	$	(6	)	$	433
	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 $2.4 million of severance costs, which included $0.5 million in adjustments recorded in 2013. On a segment basis, these restructuring costs totaled $1.1 million in North America, $0.9 million in Europe and $0.4 million in Asia Pacific. Our reserve for the 2012 realignment was $0.2 million at September 30, 2013, which we anticipate will be paid within one year.
	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 Services International Corporation, or 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 September 30, 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 $4.4 million of lease termination costs associated with office locations in North America and Europe. On a segment basis, these restructuring costs totaled $12.4 million in North America, $6.0 million in Europe and $0.6 million in Asia Pacific. Our reserve for the 2009 realignment, comprised of lease termination costs, was $0.2 million at September 30, 2013. We anticipate these costs will be paid within the next two years.

	On August 27, 2013, we amended our credit facility by increasing the overall borrowing capacity to $400.0 million from $300.0 million and extending the maturity date from December 20, 2016 to August 27, 2018. In connection with this amendment, we incurred $1.3 million in debt issuance costs, which were capitalized and included within "Other assets" in our condensed 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, American Teleconferencing Services Ltd., or 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 new 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 1.00% and 2.00%, respectively, at September 30, 2013 under our credit facility. Our interest rate on LIBOR loans, which comprised materially all of our outstanding borrowings as of September 30, 2013, was 2.22%. 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 September 30, 2013, the rate applied to the unused portion of our credit facility was 0.30%. Our credit facility contains customary terms and restrictive covenants, including financial covenants. At September 30, 2013, we were in compliance with the covenants 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 advisers under our amended and restated 2004 long-term incentive plan and our amended and restated 2000 directors stock plan, each plan as amended. Options issued under our 2004 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. We may only issue non-qualified options under our directors stock plan. The compensation committee of our board of directors administers these stock plans.
	Equity-based compensation expense is measured at the grant date, based on the fair value of the award, and is recognized over the applicable 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 included in the line items below in our condensed consolidated statements of operations (in thousands):
		Three Months Ended September 30,						Nine Months Ended September 30,
		2013			2012			2013			2012

	Equity-based compensation expense	$	2,058		$	1,929		$	5,694		$	6,113
	Restricted Stock Awards
	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 canceled. 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 unvested restricted stock awards under our stock plans from December 31, 2012 to September 30, 2013:
		Shares		Weighted-Average Grant Date Fair Value
	Unvested at December 31, 2012	1,764,672		$	8.5
	Granted	840,750		10.84
	Vested/released	(525,969	)	8.58
	Forfeited	(61,665	)	8.21
	Unvested at September 30, 2013	2,017,788		$	9.46
	The weighted-average grant date fair value of restricted stock awards granted during the nine months ended September 30, 2013 and 2012 was $10.84 and $8.97, respectively. The aggregate fair value of restricted stock vested was $0.5 million and $5.7 million for the three and nine months ended September 30, 2013, respectively, and $1.1 million and $5.7 million for the three and nine months ended September 30, 2012, respectively. During the nine months ended September 30, 2013 and the year ended December 31, 2012, we issued 367,034 and 637,686 shares, respectively, of our common stock relating to the vesting of restricted stock awards. As of September 30, 2013, we had $14.5 million of unvested restricted stock, which we will recognize over a weighted-average recognition period of 2.1 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 historically paid any cash dividends on our common stock, and we do not anticipate paying any cash dividends in the foreseeable future. Consequently, we use an expected dividend yield of zero in the Black-Scholes option valuation model. 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 options activity under our stock plans from December 31, 2012 to September 30, 2013:
		Options		Weighted-			Weighted-Average Remaining Contractual Life (in years)		Aggregate Intrinsic Value
				Average Exercise Price
	Options outstanding at December 31, 2012	87,168		$	11.23

	Options outstanding and exercisable at September 30, 2013	10,000		$	11.32		1.5		$	—
	As of September 30, 2013 and 2012, we had no remaining unvested stock options to be recorded as an expense for future periods. During the year ended December 31, 2012, we issued 109,167 shares of our common stock as a result of options exercised. No options were exercised during the nine months ended September 30, 2013.

EARNINGS PER SHARE	'
	EARNINGS PER SHARE
	Basic and Diluted Earnings 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 September 30, 2013 and 2012, 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 or 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 was the dilutive effect of unvested restricted shares and stock options for the three and nine months ended September 30, 2013 and 2012.
	The following table represents a reconciliation of the shares used in the calculation of basic and diluted net income per share from continuing operations computations contained in our condensed consolidated financial statements (in thousands, except per share data):

	Diluted net income per share from continuing operations	$	0.1	$	0.12	$	0.43	$	0.38
	The weighted-average diluted common shares outstanding for the three and nine months ended September 30, 2013 excludes the effect of an aggregate of 91,000 and 60,574 restricted shares and out-of-the-money options, respectively, because their effect would be anti-dilutive. The weighted-average diluted common shares outstanding for the three and nine months ended September 30, 2012 excludes the effect of an aggregate of 84,668 and 128,165 restricted shares, out-of-the-money options and warrants, respectively, because their effect would be anti-dilutive.

	State Telecommunications Excise Tax Matter
	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 Systems, LLC, or 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, on 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 through a timely appeal that we filed with the Tax Court of New Jersey on November 2, 2010. 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 cash flows 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 arising in the ordinary course of business 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.

	In accordance with ASC Topic 805, “Business Combinations," or ASC 805, 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.
	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. This acquisition was not individually significant. 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 $0.9 million of direct transaction costs, which are recorded in acquisition-related costs for the three and nine months ended September 30, 2013.
	ACT's financial results since its acquisition date of September 4, 2013 are primarily included in our North America segment, with immaterial operations included within our Europe and Asia Pacific segments. ACT contributed net revenues and net income from continuing operations of $3.7 million and $0.3 million, respectively, for both the three and nine months ended September 30, 2013, which are included in our condensed consolidated statements of operations.
	Copper
	On August 1, 2013, we acquired substantially all of the assets and assumed certain liabilities of the conferencing services business of The Himark Group, LLC d/b/a Copper Services, or Copper, a U.S.-based audio and web conferencing services provider. This acquisition was not individually significant. The following table summarizes the preliminary consideration paid for the assets and liabilities of this provider (in thousands):
	Negotiated sales price	$	10,750
	Preliminary working capital and other adjustments	(225		)
	Preliminary purchase price	$	10,525
	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 three and nine months ended September 30, 2013.
	Copper's financial results since its acquisition date of August 1, 2013 are included in our North America segment. Contributions to net revenues and net income from the Copper acquisition were not significant for the three and nine months ended September 30, 2013.
	Preliminary Valuation of Asset 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 condensed 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 new software-as-a-service, or SaaS-based collaboration products to those customers, and opportunities to improve performance by leveraging best practices and operational expertise. The recognized goodwill for ACT is not expected to be deductible for income tax purposes. The recognized goodwill for Copper is 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 the acquisition dates). 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 the acquisition dates during the measurement periods. The preliminary valuation of the assets acquired and liabilities assumed for these two acquisitions are as follows (in thousands):

	Preliminary Valuation Adjustments
	We performed a preliminary valuation of the assets and liabilities of both acquired companies at their respective acquisition dates. 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 "Prepaid expenses and 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 purchase 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 “Accrued expenses” under “Long-Term Liabilities.”
	Property and equipment - An adjustment of $0.4 million was recorded to adjust the net book value of ACT property and equipment to fair value giving consideration to the highest and best use of the assets. The valuation of ACT's property and equipment was based on the cost approach.
	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 incremental after-tax cash flows attributable to the subject intangible asset are then discounted to their present value. Only expected sales from current customers as of the acquisition date were used. We assumed a customer attrition rate of revenue of approximately 15% for ACT, and 30% for Copper, both of which are supported by historical retention rates. Income taxes were estimated at approximately 34% and amounts were discounted using a rate of 15%. The customer relationships were preliminarily valued at $28.9 million for our ACT acquisition under this approach and will be amortized over 10 years. The customer relationships were valued at $6.4 million for Copper under this approach and will be amortized over five 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 estimation is that the individuals subject to such agreements negatively impact 2.5% of the revenue of our ACT business if they were to violate the restrictive covenants. The non-compete agreements were valued at $0.8 million for the ACT acquisition under this approach and will be amortized over five years. The non-compete agreements were valued at $0.8 million for Copper under this approach, assuming the individuals subject to such agreements could negatively impact 10% of revenue, and will also be amortized over five years.
	Deferred tax liabilities, net - An adjustment of $5.4 million was recorded to adjust deferred taxes for the preliminary fair value adjustments made in accounting for our ACT acquisition.
	Preliminary Pre-Acquisition Contingencies Assumed
	We have evaluated and continue to evaluate pre-acquisition contingencies relating to ACT that existed as of the 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 the acquisition date. Accordingly, we have recorded our best estimates for these contingencies as part of the preliminary valuation of the assets and liabilities acquired from ACT. We continue to gather information relating to all pre-acquisition contingencies that we have assumed from ACT. 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.

SIGNIFICANT ACCOUNTING POLICIES (Policy)	9 Months Ended
	Sep. 30, 2013
Accounting Policies [Abstract]	'
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 condensed consolidated balance sheets
Accounts Receivable and Allowance for Doubtful Accounts	'
	Our allowance for doubtful accounts represents reserves for receivables that reduce accounts receivable to amounts expected to be collected. 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.
	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	'
	We amortize these capitalized costs on a straight-line basis over the estimated life of the related software, not to exceed five years.
	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 condensed consolidated balance sheets.
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. No impairment of goodwill was identified in the year ended December 31, 2012, the date of our most recent assessment. As of September 30, 2013, we are not aware of any events that would lead to an impairment; therefore, we do not believe that any of our reporting units are at risk of failing step one of the goodwill impairment test.
Cost Method Investments	'
	This investment is subject to fluctuations in foreign currency exchange rates.
	These three 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 would be recognized.
	These amounts were included as a component of “Other assets” on our condensed 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 September 30, 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 which are generally billed on a per minute basis. To a lesser extent, we charge subscription-based and license fees and have fixed-period minimum revenue commitments. Revenues related to our virtual meeting solutions primarily consist of usage fees which are recognized ratably over the contracted term of the agreement. These revenues may also include set-up fees and maintenance and update fees, which are typically also recognized ratably over the life of the contract. 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 condensed consolidated balance sheets.
USF Charges	'
	USF Charges
	In accordance with Federal Communications Commission rules, we are required to contribute to the federal Universal Service Fund, or USF, for some of our solutions, which we recover from our applicable customers and remit to the Universal Service Administration Company. 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"
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 condensed 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 income” 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 income” component of shareholders’ equity in our condensed consolidated balance sheets.
Treasury Stock	'
	Treasury Stock
	All treasury stock transactions are recorded at cost, and all shares of treasury stock repurchased are retired
Preferred Stock	'
	Under the terms of our amended and restated articles of incorporation, our board of directors is empowered to issue preferred stock without shareholder action.
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 condensed consolidated statements of operations. See Note 3 to our condensed 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 condensed 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 acquisitions.
Excise and Sales Tax	'
	We believe we have appropriately accrued for these contingencies. In the event that actual results differ from these reserves, or new information becomes available, we may need to make adjustments, which could materially impact our financial condition and results of operations. In addition, states may disagree with our method of assessing and remitting such taxes, or additional states may subject us to inquiries regarding such taxes.
	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 condensed consolidated balance sheets.
	Excise and Sales Tax
	Some of our solutions may be subject to telecommunications excise tax and sales taxes in states where we have not collected and remitted such taxes from our customers.
Income Taxes	'
	Income Taxes
	Income taxes are determined under the asset and liability method as required by Accounting Standards Codification, or 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 condensed 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.
Fair Value Measurements	'
	Fair Value Measurements
	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. The fair value amounts for cash and equivalents, accounts receivable, net, and 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 September 30, 2013 and December 31, 2012 were 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.
New and Recently Adopted Accounting Pronouncements	'
	New and Recently Adopted Accounting Pronouncements
	In July 2013, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update, or 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 condensed consolidated financial position or results of operations.
