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.
Basis of Presentation	Basis of Presentation The Company's fiscal year ends on December 31 of each calendar year. The accompanying interim condensed consolidated financial statements are unaudited and have been prepared on substantially the same basis as our annual consolidated financial statements for the fiscal year ended December 31, 2016. In the opinion of the Company's management, these interim condensed consolidated financial statements reflect all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair statement of our financial position, results of operations and cash flows for the periods presented. The preparation of financial statements in conformity with generally accepted accounting principles 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 revenue and expenses during the reporting periods. Actual results could differ from these estimates.
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.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update ASU 2014-09, “Revenue from Contracts with Customers” (Subtopic 606), which supersedes most existing revenue recognition guidance under U.S. generally accepted accounting principles (“U.S. GAAP”). The core principle of ASU 2014-09 is to recognize revenue 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). The Company commenced our evaluation of the impact of the pending adoption of ASU 2014-09 on our consolidated financial statements in late 2016 and we are actively reviewing hundreds of customer contracts. Under the ASU, revenue will be recognized as the customer obtains control of the goods and services promised in the contract (i.e., performance obligations). Given the nature of our services and terms and conditions in our contracts, the customer obtains control as we deliver services under the contract. We recognize the majority of our revenue on a monthly recurring basis as we deliver our services. The Company intends to use the retrospective approach with the cumulative effect of initially adopting ASU 2014-09 on January 1, 2018. Based on current analysis, management does not expect the adoption of ASU 2014-09 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”. This guidance 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 August 2016, the FASB issued ASU 2016-09, “Statement of Cash Flows-Classification of Certain Cash Receipts and Cash Payments” (Subtopic 230). This guidance clarifies how entities should classify certain cash receipts and cash payments on the statement of cash flows. The amendment addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. These updates are effective for annual reporting periods beginning after December 15, 2017, and interim periods within those annual periods, with early adoption permitted. The guidance should be applied retrospectively unless it is impractical to do so; in which case, the guidance should be applied prospectively as of the earliest date practicable. Management does not expect the adoption of ASU 2016-09 to have a material impact on our financial statements. In November 2016, the FASB issued ASU 2016-18, “Statement of Cash Flows-Restricted Cash” (Subtopic 230). These amendments require that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. As a result, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning of period and end of period total amounts shown on the statement of cash flows. The amendments do not provide definition of restricted cash or restricted cash equivalents. Effective date for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted. Management does not expect the adoption of ASU 2016-18 to have any impact on our financial statements and disclosures, as restricted cash is currently included in the change of cash on the statement of cash flows. In January 2017, the FASB issued ASU 2017-04, “Intangibles - Goodwill and Other: Simplifying the Test for Goodwill Impairment” (Subtopic 350). This guidance simplifies the accounting for goodwill impairment by removal of Step 2 of the goodwill impairment test. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. For public companies, the standard will be effective for calendar year-end December 15, 2020. Earlier adoption is permitted for any impairment test performed after January 1, 2017. Management adopted this standard on a prospective basis beginning July 1, 2017.
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.
Intangible Assets	Intangible Assets The Company assesses the impairment of purchased intangible assets subject to amortization when events and circumstances indicate that the carrying value of the assets might not be recoverable. Fair value of our intangible assets is determined using the relief from royalty methodology. This approach involves two steps: (a) estimating reasonable royalty rates for each intangible asset and (b) applying these royalty rates to a net revenue stream and discounting the resulting cash flows to determine fair value. This fair value is then compared with the carrying value of each intangible asset. If the carrying amount of the intangible asset is greater than its implied fair value, an impairment in the amount of the excess is recognized and charged to operations. The determination of related estimated useful lives and whether or not these assets are impaired involves significant judgments, related primarily to the future profitability and/or future value of the assets. Changes in the Company’s strategic plan and/or other-than-temporary changes in market conditions could significantly impact these judgments and could require adjustments to recorded asset balances. Long-lived assets are evaluated for impairment at least annually, as well as whenever an event or change in circumstances has occurred that could have a significant adverse effect on the fair value of long-lived assets.
