SIGNIFICANT 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. 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 include 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, 2012 and 2011 we had $0.6 million and $0.4 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, 2012 and 2011 was earned but unbilled revenue of approximately $6.7 million and $6.6 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 $1.1 million, $0.6 million and $0.9 million in 2012, 2011 and 2010, respectively. Write-offs against the allowance for doubtful accounts were $0.9 million, $0.9 million and $1.0 million in 2012, 2011 and 2010, 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, $0.6 million and $0.9 million as of December 31, 2012, 2011 and 2010, 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 ten 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 sold as part of our service offerings as part of "Property and Equipment, Net" on our consolidated balance sheets. For the years ended December 31, 2012, 2011 and 2010, we capitalized approximately $15.3 million, $15.3 million and $16.4 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, 2012, 2011, and 2010, was approximately $12.1 million, $10.2 million and $6.1 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 included 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. Based on our qualitative assessment this year, the fair value of our North America and Europe reporting units substantially exceeded their respective carrying values, and thus no quantitative assessment was required. For our Asia Pacific reporting unit, we were unable to conclude that it was more likely than not that fair value exceeded carrying value as a result of the qualitative analysis. Therefore, step one of the quantitative impairment test was performed for our Asia Pacific reporting unit, with estimated fair value exceeding carrying value by more than 20%. No impairment of goodwill was identified in any of the years ended December 31, 2012, 2011 or 2010.
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 $0.9 million, $0.5 million and $0.3 million during 2012, 2011 and 2010, respectively, and are recognized as "Asset impairments" in our consolidated statements of operations.
Cost Method Investments	Cost Method Investments 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 our investment at an annual rate of 8% that will be due with the principal balance in September 2014. The investment is accounted for under the cost method, and interest will be accrued through maturity. The investment is 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. The principal and accrued interest of this promissory note is carried on our consolidated balance sheet at December 31, 2012 as a component of "Other assets." In June 2011, we invested approximately $1.0 million in a privately-held conferencing company. The investment is accounted for under the cost method and is 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. The cost of this investment is carried on our consolidated balance sheet at December 31, 2012 as a component of "Other assets."
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. 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 consolidated balance sheets.
USF Charges	USF Charges In accordance with FCC 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 USAC. We present the USF charges that we collect and remit on a net basis, with charges to our customers netted against the cost we remit.
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. During 2010, we wrote-off $4.7 million of "Accumulated other comprehensive gain" as part of loss on disposal in discontinued operations, which represents the historical "Accumulated other comprehensive gain" for our discontinued businesses.
Treasury Stock	Treasury Stock All treasury stock transactions are recorded at cost. 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 year ended December 31, 2011, we repurchased approximately 3.0 million shares of our common stock in the open market for approximately $22.0 million at an average price of $7.41 per share. During the years ended December 31, 2012 and 2011, we redeemed 246,735 and 208,944 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 $2.0 million and $1.8 million, respectively, in taxes on our employees' behalf. We retire all shares of treasury stock repurchased.
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 existing 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. 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.
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 2012, 2011 and 2010 was $8.9 million, $16.9 million and $10.2 million, respectively. As of December 31, 2012 and 2011, we had $0.3 million and $0.0 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 September 2011, the FASB, issued ASU No. 2011-08 "Intangibles - Goodwill and Other (Topic 350): Testing Goodwill for Impairment," which modifies the process of testing goodwill for impairment. The update allows an entity to first assess qualitative factors to determine whether it is necessary to perform the two-step quantitative goodwill impairment test. An entity is not required to calculate the fair value of a reporting unit unless the entity determines it is more likely than not, based on a qualitative assessment, the fair value of a reporting unit is less than its carrying amount. The guidance also includes a number of events and circumstances to consider in conducting the qualitative assessment. This guidance is effective for public companies for fiscal years beginning on or after December 15, 2011. We applied this guidance effective with our 2012 annual goodwill impairment test. See further discussion in Note 2 to our consolidated financial statements. In July 2012, the FASB issued ASU No. 2012-02, "Intangibles - Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment," which allows a company the option to first assess qualitative factors to determine whether it is necessary to perform a quantitative impairment test. Under that option, a company would no longer be required to calculate the fair value of an indefinite-lived intangible asset unless the company determines, based on that qualitative assessment, that it is more likely than not that the fair value of the indefinite-lived intangible asset is less than its carrying amount. This guidance is effective for annual and interim indefinite-lived intangible asset impairment tests performed for fiscal years beginning after September 15, 2012. Early adoption is permitted. The adoption of this guidance is not expected to have a material impact on our financial position or results of operations. In December 2011, the FASB issued ASU No. 2011-11 "Disclosures about Offsetting Assets and Liabilities," which amends certain provisions in ASC 210 "Balance Sheet." Subsequently in January 2013, the FASB issued ASU No. 2013-01 which amends the scope of ASU No. 2011-11. These provisions require additional disclosures for certain financial instruments that are presented net for financial statement presentation or are subject to a master netting arrangement, including the gross amount of the asset and liability as well as the impact of any net amount presented in the consolidated financial statements. These provisions are effective for fiscal and interim periods beginning on or after January 1, 2013. The adoption of this guidance is not expected to have a material impact on our financial position or results of operations. In February 2013, the FASB issued ASU No. 2013-02, "Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income," which amends certain provisions in ASC 220 "Comprehensive Income." These provisions require the disclosure of significant amounts that are reclassified out of other comprehensive income into net income in its entirety during the reporting period. These provisions are effective for fiscal and interim periods beginning after December 15, 2012. The adoption of this guidance is not expected to have a material impact on our financial position or results of operations.
