Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation The condensed consolidated financial statements include the accounts of Glowpoint and our 100%-owned subsidiary, GP Communications, LLC, whose business function is to provide interstate telecommunications services for regulatory purposes. All material inter-company balances and transactions have been eliminated in consolidation.
Reclassifications	Reclassifications Certain prior year amounts have been reclassified to conform with the current year presentation.
Use of Estimates	Use of Estimates Preparation of the condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual amounts could differ from the estimates made. We continually evaluate estimates used in the preparation of the condensed consolidated financial statements for reasonableness. Appropriate adjustments, if any, to the estimates used are made prospectively based upon such periodic evaluation. The significant areas of estimation include determining the allowance for doubtful accounts, deferred tax valuation allowance, accrued sales taxes, the valuation of goodwill, the valuation of intangible assets and their estimated lives, and the estimated lives and recoverability of property and equipment.
Accounting Standards Updates	Accounting Standards Updates On May 28, 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. This ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The new standard is effective for us on January 1, 2017. Early application is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. We are evaluating the effect that ASU 2014-09 will have on our consolidated financial statements and related disclosures. The FASB has issued for public comment a proposed ASU that would defer the effective date of ASU 2014-09 by one year. We have not yet selected a transition method nor have we determined the effect of the standard on our ongoing financial reporting. In August 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements - Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern, which is intended to define management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. Specifically, ASU 2014-15 provides a definition of the term substantial doubt and requires an assessment for a period of one year after the date that the financial statements are issued (or available to be issued). It also requires certain disclosures when substantial doubt is alleviated as a result of consideration of management’s plans and requires an express statement and other disclosures when substantial doubt is not alleviated. The new standard will be effective for reporting periods beginning after December 15, 2016, with early adoption permitted. Management is currently evaluating the impact of the adoption of ASU 2014-15 on our financial statements and disclosures. In April 2015, the FASB issued ASU 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs, which requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. This ASU requires retrospective adoption and will be effective for fiscal years beginning after December 15, 2015 and for interim periods within those fiscal years. We expect the adoption of this guidance will not have a material impact on our financial statements.
Revenue Recognition	Revenue Recognition Revenue billed in advance for video collaboration services is deferred until the revenue has been earned, which is when the related services have been performed. Other service revenue, including amounts passed through based on surcharges from our telecom carriers, related to the network services and collaboration services are recognized as service is provided. As the non-refundable, upfront installation and activation fees charged to the subscribers do not meet the criteria as a separate unit of accounting, they are deferred and recognized over the 12 to 24 month estimated life of the customer relationship. Revenue related to professional services is recognized at the time the services are performed. Revenues derived from other sources are recognized when services are provided or events occur.
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts We record an allowance for doubtful accounts based on specifically identified amounts that are believed to be uncollectible. We also record additional allowances based on our aged receivables, which are determined based on historical experience and an assessment of the general financial conditions affecting our customer base. If our actual collections experience changes, revisions to our allowance may be required. After all attempts to collect a receivable have failed, the receivable is written off against the allowance. We do not obtain collateral from our customers to secure accounts receivable.
Taxes Billed to Customers and Remitted to Taxing Authorities	Taxes Billed to Customers and Remitted to Taxing Authorities We recognize taxes billed to customers in revenue and taxes remitted to taxing authorities in our cost of revenue.
Impairment of Long-Lived Assets and Intangible Assets	Impairment of Long-Lived Assets and Intangible Assets We evaluate impairment losses on long-lived assets used in operations, primarily fixed assets and purchased intangible assets subject to amortization, when events and circumstances indicate that the carrying value of the assets might not be recoverable. For purposes of evaluating the recoverability of long-lived assets, the undiscounted cash flows estimated to be generated by those assets are compared to the carrying amounts of those assets. If and when the carrying values of the assets exceed their fair values, then the related assets will be written down to fair value.
Capitalized Software Costs	Capitalized Software Costs The Company capitalizes certain costs incurred in connection with developing or obtaining internal-use software. All software development costs have been appropriately accounted for as required by ASC Topic 350-40 “Intangible – Goodwill and Other – Internal-Use Software”. Capitalized software costs are included in Property and Equipment on our condensed consolidated balance sheets and are amortized over three to four years. Software costs that do not meet capitalization criteria are expensed as incurred.
