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	Reclassification 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 In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers (ASU 2014-09), which supersedes most existing revenue recognition guidance under U.S. GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services. ASU 2014-09 defines a five step process to achieve this core principle and, in doing so, more judgment and estimates may be required within the revenue recognition process than are required under existing U.S. GAAP. The standard is effective for annual periods beginning after December 15, 2017, and interim periods therein, using either of the following transition methods: (i) a full retrospective approach reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients, or (ii) a retrospective approach with the cumulative effect of initially adopting ASU 2014-09 recognized at the date of adoption (which includes additional footnote disclosures). We continue to evaluate the impact of the pending adoption of ASU 2014-09 on our consolidated financial statements and believe that the Company will use the retrospective approach with the cumulative effect of initially adopting ASU 2014-09 recognized at the date of adoption. Management does not expect the adoption of ASU 2014-09 to have a material impact on our financial statements and disclosures. In November 2015, the FASB issued ASU 2015-17, Income Taxes (Subtopic 740-10). The amendments in this update require deferred tax liabilities and assets be classified as non-current regardless of the classification of the underlying assets and liabilities. For public companies, the amendments will be effective for financial statements issued for annual periods beginning after December 15, 2016. Earlier application is permitted. Management does not expect the adoption of ASU 2015-17 to have a material impact on our financial statements and disclosures. In February 2016, the FASB created Topic 842 and issued ASU 2016-02, Leases. The guidance in this update supersedes Topic 840, Leases. This ASU requires lessees to recognize a right-of-use assets and a lease liability, initially measured at the present value of the lease payments on the balance sheet. For public companies, the amendments will be effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Earlier application is permitted. Management is currently evaluating the impact of the adoption of ASU 2016-02 on our financial statements and disclosures. In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Subtopic 718). The guidance in this update involves several aspects of the accounting for share-based payment transactions, including income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. For public companies, the amendments will be effective for financial statements issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Earlier application is permitted for any interim or annual period. Management does not expect the adoption of ASU 2016-09 to have a material impact on our financial statements and disclosures.
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 estimated life of the customer relationship. Revenue related to professional services is recognized at the time the services are performed, and presented as required by ASC Topic 605 “Revenue Recognition”. Revenues derived from other sources are recognized when services are provided or events occur.
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts We perform ongoing credit evaluations of our customers. 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.
Goodwill, Intangible Assets and Long-Lived Assets	Goodwill, Intangible Assets and Long-Lived Assets Goodwill is not amortized but is subject to periodic testing for impairment in accordance with ASC Topic 350 “Intangibles - Goodwill and Other - Testing Indefinite-Lived Intangible Assets for Impairment”. We test goodwill for impairment on an annual basis or more frequently if events occur or circumstances change indicating that the fair value of the goodwill may be below its carrying amount. We also 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.
