Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	2. DISCONTINUED OPERATIONS On March 3, 2015, we divested several of our agent-based businesses for $275.0 million in cash. The divestiture resulted in a 2015 gain of $48.2 million on an after-tax basis which was included within income from discontinued operations. The $48.2 million gain included a $21.6 million tax benefit in 2015 due to the deferred tax benefit associated with excess outside basis over financial reporting basis. The following table summarizes the results of discontinued operations for the three months ended March 31, 2015: Three months (Amounts in thousands) 2015 Revenue $ 102,251 Operating income 3,300 Gain on disposal 48,556 Income before income tax expense 51,683 Income tax expense 19,817 Income from discontinued operations $ 31,866 There was no income or loss from discontinued operations during the first quarter of 2016. We have agreed to indemnify the buyer, up to the full purchase price, with respect to the equity interests of the companies we sold, title to the equity and assets sold and the authority of the Company to sell the equity and assets. The Company has also agreed to indemnify the buyer for breaches of other representations and warranties in the purchase agreement for up to $13.75 million in losses. On February 24, 2016, we entered into a sales agreement for certain land, building and improvements which were primarily occupied by the agent businesses that we divested on March 3, 2015. The sale is anticipated to close in the second quarter of 2016. The net book value of these assets, $19.0 million as of March 31, 2016, is presented in our condensed consolidated balance sheet as assets held for sale and measured at the lower of their carrying amount or fair value less costs to sell.

Acquisitions

Business Combinations [Abstract]
Acquisitions	3. ACQUISITIONS Synrevoice On March 14, 2016, we completed the acquisition of substantially all of the assets of Synrevoice Technologies, Inc. (“Synrevoice”). Synrevoice, based in Markham, Ontario, is a provider of messaging and notification services to the K-12 education and commercial markets in North America. The purchase price was approximately $9.3 million and was funded with cash on hand. This business is included in the Interactive Services reportable segment. In the preliminary purchase price allocation, approximately $4.9 million was allocated to goodwill, which is partially deductible for income tax purposes, and $6.5 million to other intangible assets. The primary factors that contributed to a purchase price resulting in the recognition of goodwill for the acquisition of Synrevoice were the expansion of our interactive services further into the education vertical market and anticipated synegies which are expected to result in a more efficient and faster growing K-12 business in North America. ClientTell On November 2, 2015, we completed the acquisition of ClientTell, Inc., and ClientTell Labs, LLC (collectively “ClientTell”), which provide automated notifications and lab reporting services in the healthcare industry. The purchase price was approximately $38.4 million in cash, plus assumed liabilities, and was funded with cash on hand. Up to an additional $10.5 million in cash may be paid based on achievement of certain financial objectives during the five years ending December 31, 2020. The fair value of this contingent consideration arrangement was $5.4 million as of the date of acquisition and $5.9 million as of March 31, 2016. Approximately $15.0 million of the purchase price was allocated to goodwill and $26.3 million to other intangible assets. The goodwill is deductible for income tax purposes. The primary factors that contributed to a purchase price resulting in the recognition of goodwill for the acquisition of ClientTell were the expansion of our interactive services further into the healthcare vertical market, anticipated synergies, and other intangibles that do not qualify for separate recognition. This business has been integrated into the Interactive Services reportable segment. Magnetic North On October 31, 2015, we completed the acquisition of Magnetic North Software Limited (“Magnetic North”) for approximately $38.7 million in cash net of cash acquired, plus assumed liabilities, which was funded with cash on hand. Magnetic North is a U.K.-based provider of inbound/outbound/blended, multi-channel customer engagement technology solutions with multi-media routing, advanced analytics and compliance functionality and integrated, hosted voice and unified communications platforms to customers throughout EMEA and the Americas. In the preliminary purchase price allocation, approximately $24.5 million was allocated to goodwill and $16.4 million to other intangible assets. The goodwill is not deductible for income tax purposes. The primary factors that contributed to a purchase price resulting in the recognition of goodwill for the acquisition of Magnetic North were its portfolio of complementary customer contact center and unified communications solutions, anticipated synergies, and other intangibles that do not qualify for separate recognition. This business has been integrated into the Unified Communications Services reportable segment. SharpSchool Effective June 1, 2015, we completed the acquisition of substantially all of the assets of Intrafinity, Inc., doing business as SharpSchool (“SharpSchool”), a leading provider of website and content management system software-as-a-service solutions for the K-12 education market. The purchase price was approximately $17.2 million and was funded with cash on hand. In the preliminary purchase price allocation, goodwill of $8.3 million, partially deductible for tax purposes under Canadian tax rules governing asset acquisitions, and finite-lived intangible assets of $9.1 million were recorded. The primary factors that contributed to a purchase price resulting in the recognition of goodwill for the acquisition of SharpSchool were the expansion of our interactive services further into the education vertical market and anticipated synergies which are expected to result in a more efficient and faster growing K-12 business for West. SharpSchool has been integrated into the Interactive Services reportable segment. The following table summarizes the preliminary estimated fair values of the assets acquired and liabilities assumed at the respective acquisition dates for Synrevoice and Magnetic North and the final fair value of assets acquired and liabilities assumed for ClientTell and SharpSchool.

The excess of the acquisition costs over the fair value of the assets acquired and liabilities assumed for the purchase of Magnetic North and Synrevoice were assigned to goodwill based on preliminary estimates. We are in the process of completing the acquisition accounting for certain intangible assets and liabilities. The process of completing the acquisition accounting involves numerous time consuming steps for information gathering, verification and review. We expect to finalize this process within twelve months following the respective acquisition dates. Pro forma The following unaudited pro forma financial information presents the combined results of operations as if the acquisitions of Synrevoice, ClientTell, Magnetic North, and SharpSchool (collectively, the acquirees) occurred as of the beginning of the period presented. The pro forma results contained in the table below include adjustments for amortization of acquired intangibles, finance and acquisition costs as well as related income taxes.

Fair Value Disclosures [Abstract]
Fair Value Disclosures	7. FAIR VALUE DISCLOSURES FASB guidance establishes a three-level fair value hierarchy based upon assumptions (inputs) used to price assets or liabilities. The three levels of inputs used to measure fair value are as follows: • Level 1 – Unadjusted quoted prices in active markets for identical assets or liabilities. • Level 2 – Observable inputs other than those included within Level 1, such as quoted prices for similar assets and liabilities in active markets or quoted prices for identical assets or liabilities in inactive markets, and • Level 3 – Unobservable inputs for assets or liabilities reflecting our assumptions and best estimate of what inputs market participants would use in pricing the asset or liability. The categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Following is a description of the valuation methodologies used for assets and liabilities measured at fair value. Trading Securities (Asset). Investments—Debt and Equity Securities We evaluate classification within the fair value hierarchy each reporting period. There were no transfers between any levels of the fair value hierarchy during the periods presented. The carrying amount of the trading securities of $61.0 million and $60.1 million at March 31, 2016 and December 31, 2015, respectively, were equal to the quoted prices in active markets for identical assets. The fair value of our 2022 Senior Notes based on market quotes, which we determined to be Level 2 inputs, at March 31, 2016 and December 31, 2015 was approximately $922.5 million and $862.5 million, respectively, compared to the carrying amount of $1.0 billion. The fair value of our senior secured 2018 Maturity Term Loans and 2021 Maturity Term Loans was estimated using current market quotes on comparable debt securities from various financial institutions. All of the inputs used to determine the fair market value of our Senior Secured Credit Facilities are Level 2 inputs and obtained from an independent source. The fair value of our 2018 Maturity Term Loans and 2021 Maturity Term Loans at March 31, 2016 was approximately $2,023.4 million compared to the carrying amount of $2,036.8 million. The fair value of our 2018 Maturity Term Loans and 2021 Maturity Term Loans at December 31, 2015 was approximately $2,033.2 million compared to the carrying amount of $2,063.3 million. The fair value of our 2019 Maturity TLA Loans based on recent trading activity, which we determined to be Level 2 inputs, at March 31, 2016 was approximately $321.7 million compared to the carrying amount of $332.5 million. The fair value of our TLA at December 31, 2015, was approximately $323.4 million compared to the carrying amount of $336.9 million. A Level 3 liability of $5.9 million and $5.6 million was recognized as of March 31, 2016 and December 31, 2015, respectively, for contingent consideration related to the acquisition of ClientTell (see Note 3). The liability was measured at fair value using a Monte Carlo simulation approach and was based on estimated revenues and the present value of related payments over the earn-out period.

Stock-Based Compensation	8. STOCK-BASED COMPENSATION 2006 Executive Incentive Plan Stock options granted under the West Corporation 2006 Executive Incentive Plan (“2006 EIP”) prior to 2012 vest over a period of five years, with 20% of the stock option becoming exercisable on each of the first through fifth anniversaries of the grant date. Stock options granted under the 2006 EIP in 2012 and 2013 vest over a period of four years, with 25% of the stock option becoming exercisable on each of the first through fourth anniversaries of the grant date. Once an option has vested, it generally remains exercisable until the tenth anniversary of the grant date so long as the participant continues to provide services to the Company. 2013 Long-Term Incentive Plan Prior to the completion of our initial public offering, we adopted, and subsequently amended, the 2013 Long-Term Incentive Plan (as amended, “2013 LTIP”), which is intended to provide our officers, employees, non-employee directors and consultants with added incentive to remain employed by or perform services for us and align such individuals’ interests with those of our stockholders. Under the terms of the 2013 LTIP, 8,500,000 shares of common stock were made available for stock options, restricted stock or other types of equity awards, subject to adjustment for stock splits and other similar changes in capitalization. The number of available shares under the 2013 LTIP is reduced by the aggregate number of shares underlying each award. To the extent that shares subject to an outstanding award granted under the 2013 LTIP are not issued or delivered by reason of the expiration, termination, cancellation or forfeiture of such award or by reason of the settlement of such award in cash, then such shares will again be available under the 2013 LTIP (excluding shares withheld by the Company to pay withholding taxes related to an award under the 2013 LTIP). Stock options granted under the 2013 LTIP vest over a period of four years, with 25% of the stock option becoming exercisable on each of the first through fourth anniversaries of the grant date. Once an option has vested, it generally remains exercisable until the tenth anniversary of the grant date so long as the participant continues to provide services to the Company. Restricted stock granted under the 2013 LTIP, which is time-vested, vests over a period of three or four years (excluding awards to directors which vest over a six to twelve month period), with a ratable portion of the restricted stock award vested on each anniversary of the grant date until fully vested, unless earlier forfeited as a result of termination of service to the Company prior to the applicable vesting date. Dividends are payable in respect of shares of unvested restricted stock either at the time the dividend is paid to stockholders or upon vesting of the restricted stock in accordance with the terms of the applicable restricted stock award agreement. 2006 Executive Incentive Plan and 2013 Long-Term Incentive Plan – Stock Options The following table presents the stock or stock option activity under the 2006 EIP and 2013 LTIP for the three months ended March 31, 2016. Stock or Options Available for Grant Options Outstanding Number of Shares Weighted Average Exercise Price Balance at January 1, 2016 5,868,283 2,280,030 $ 27.08 Options exercised — (7,250 ) 13.12 Options canceled or forfeited (2013 LTIP) 5,495 (5,495 ) 23.46 Options canceled or forfeited (2006 EIP) — (4,763 ) 27.35 Restricted stock granted (594,344 ) — — Restricted stock canceled 34,584 — — Balance at March 31, 2016 5,314,018 2,262,522 $ 27.13 At March 31, 2016, we expect that approximately 2.3 million options granted and outstanding will vest. At March 31, 2016, the intrinsic value of options vested and exercisable was approximately $0.7 million. The aggregate intrinsic value of options outstanding at March 31, 2016 was approximately $0.7 million. The aggregate intrinsic value of options outstanding, vested and expected to vest at March 31, 2016 was approximately $0.7 million. The following table presents information regarding the options granted under the 2006 EIP and 2013 LTIP at March 31, 2016: Outstanding Exercisable Range of Exercise Prices Number of Options Weighted Average Remaining Contractual Life (years) Weighted Average Exercise Price Number of Options Weighted Average Exercise Price $0.00 - $13.12 61,886 0.67 $ 13.12 61,886 $ 13.12 13.13 - 28.88 1,685,482 6.20 25.11 1,469,872 25.32 28.89 - 50.88 497,156 5.30 33.89 497,156 33.89 50.89 - 84.80 17,998 4.26 77.74 17,998 77.74 $0.00 - $84.80 2,262,522 5.84 $ 27.13 2,046,912 $ 27.50 No stock options have been awarded since April 1, 2014. Restricted Shares, Restricted Stock Units and Performance-Based Restricted Stock Units During the three months ended March 31, 2016, pursuant to our agreement with our non-employee directors who are not affiliated with our former sponsors, we issued 13,344 shares of common stock with an aggregate fair value of approximately $300,000. These shares vest on the one-year anniversary of the award. During the three months ended March 31, 2016, we issued 396,500 restricted stock awards and restricted stock units to certain key employees. These awards vest ratably with 25% of the award vesting on each of the first through fourth anniversaries of the award date. The fair value of these awards at the date of grant was approximately $9.0 million and will be recognized over the remaining vesting period of approximately 3.9 years as of March 31, 2016. During the three months ended March 31, 2016, we issued 184,500 performance-based restricted stock units to certain key executives. Each performance-based restricted stock unit represents a contingent right to receive between zero and 1.75 shares of West common stock. These performance-based restricted stock units will vest based on the Company’s total shareholder return (“TSR”) percentile ranking over the applicable performance period as compared to the TSR of companies included in the Russell 2000 on both the first and last day of the performance period, which began on March 1, 2016 and ends on February 28, 2019. The fair value of these awards at the date of grant was approximately $4.1 million and will be recognized over the remaining vesting period of approximately 2.9 years as of March 31, 2016. 2013 Employee Stock Purchase Plan During the fourth quarter of 2013, we implemented the 2013 Employee Stock Purchase Plan (“ESPP”), under which the sale of 1.0 million shares of our common stock has been authorized and reserved. Employees may designate up to 50% of their annual compensation for the purchase of stock, subject to a per person limit of 2,000 shares in any offering period or calendar year. The price for shares purchased under the ESPP is 85% of the market closing price on the last day of the quarterly purchase period. No employee will be authorized to purchase common stock through the ESPP if, immediately after the purchase, the employee (or any other person whose stock would be attributed to such employee under U.S. tax law) would own stock and/or hold outstanding options to purchase stock possessing five percent (5%) or more of the total combined voting power or value of all classes of stock of the Company or of any parent of the Company or any subsidiary. In addition, no participant will be entitled to purchase stock under the ESPP at a rate which, when aggregated with his or her rights to purchase stock under all other employee stock purchase plans of the Company and its subsidiaries, exceeds $25,000 in fair market value, determined as of the date of grant (or such other limit as may be imposed by U.S. tax law), for each calendar year in which any option granted to the participant under any such plans is outstanding at any time. During the three months ended March 31, 2016, 72,026 shares were issued under the ESPP. As of March 31, 2016, 629,422 shares had been issued under the ESPP since the plan’s inception. We recognized compensation expense for this plan of $0.4 million in each of the three months ended March 31, 2016 and 2015. Share-Based Compensation Expense For the three months ended March 31, 2016 and 2015, share-based compensation expense was $7.7 million and $5.4 million, respectively. At March 31, 2016 and 2015, there was approximately $0.8 million and $6.0 million, respectively, of unrecorded and unrecognized compensation expense, adjusted for estimated forfeitures, related to unvested share-based compensation on stock options under the 2006 EIP and 2013 LTIP, which will be recognized over the remaining vesting period of approximately 1.6 years as of March 31, 2016. At March 31, 2016 and 2015, there was approximately $50.1 million and $37.5 million, respectively, of unrecorded and unrecognized compensation expense, related to unvested share-based compensation on restricted stock under the 2013 LTIP, which will be recognized over the remaining vesting period of approximately 2.8 years as of March 31, 2016.

Earnings Per Share [Abstract]
Earnings Per Share	9. EARNINGS PER SHARE Diluted earnings per share reflects the potential dilution that could result if options or other contingently issuable shares were exercised or converted into common stock and notional shares from the Nonqualified Deferred Compensation Plan were granted. Diluted earnings per common share assumes the exercise of stock options using the treasury stock method. Three months ended March 31, (Amounts in thousands, except per share amounts) 2016 2015 Earnings per common share- basic: Continuing operations $ 0.54 $ 0.58 Discontinued operations — 0.38 Total earnings per common share-basic $ 0.54 $ 0.96 Earnings per common share- diluted: Continuing operations $ 0.53 $ 0.56 Discontinued operations — 0.37 Total earnings per common share-diluted $ 0.53 $ 0.93 Weighted average number of shares outstanding: Basic common 83,149 84,125 Dilutive impact of Equity Incentive Plans: Common shares 1,466 2,101 Diluted common shares 84,615 86,226 Diluted earnings per share is computed using the weighted-average number of common shares and dilutive potential common shares outstanding during the period. Dilutive potential common shares result from the assumed exercise of outstanding stock options, by application of the treasury stock method that has a dilutive effect on earnings per share. At March 31, 2016 and 2015, 2,031,895 and 41,323 stock options, respectively, were outstanding with an exercise price equal to or exceeding the market value of our common stock and were therefore excluded from the computation of shares contingently issuable upon exercise of the options.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	12. COMMITMENTS AND CONTINGENCIES In the ordinary course of business, we and certain of our subsidiaries are defendants in various litigation matters and are subject to claims from our clients for indemnification, some of which may involve claims for damages that are substantial in amount. Accruals have been made with respect to these matters, where appropriate, which are reflected in the Company’s consolidated financial statements. The Company may enter into discussions regarding settlement of these matters, and may enter into settlement agreements, if it believes settlement is in the best interest of the Company. The matters discussed below, if decided adversely to or settled by the Company, individually or in the aggregate, may result in liability material to the Company’s financial condition and/or results of operations. There are asserted claims against the Company where an unfavorable outcome is considered to be reasonably possible. These claims can generally be categorized in the following areas: (l) commercial disputes with customers or other business partners, which may involve assertion of a breach of the Company’s legal or contractual obligations to the customer or a claim for indemnification for third party losses; and (2) other matters which may include issues such as employment related claims. The Company’s estimates of the range of reasonably possible losses in excess of any amounts accrued for such claims is $0 to $20 million for all of the matters described above. The estimated range of reasonably possible losses is based on information currently available and involves elements of judgment and significant uncertainties. As additional information becomes available and the resolution of the uncertainties becomes more apparent, it is possible that actual losses may exceed even the high end of the estimated range. In connection with the sale of certain of our agent-based businesses to Alorica Inc., we agreed to indemnify the buyer, up to the full purchase price of $275.0 million, with respect to the equity interests of the companies we sold, title to the equity and assets sold and the authority of the Company to sell the equity and assets. The Company has also agreed to indemnify the buyer for breaches of other representations and warranties in the purchase agreement for up to $13.75 million in losses and for certain other matters.
