Basis of Presentation and Significant Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies	2. Basis of Presentation and Significant Accounting Policies The accompanying condensed consolidated financial statements as of March 31, 2016, and for the three and nine months ended March 31, 2016 and 2015 have been prepared by the Company, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted pursuant to such rules and regulations. However, the Company believes that the disclosures are adequate to make the information presented not misleading. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto, included in the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2015. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair statement have been included. The condensed consolidated balance sheet as of June 30, 2015 has been derived from the audited consolidated financial statements as of that date but does not include all of the information and footnotes included in the Company’s Annual Report on Form 10-K for the year ended June 30, 2015. The results of operations for the three and nine months ended March 31, 2016 are not necessarily indicative of the operating results to be expected for the full fiscal year or any future periods. Correction of Prior Period Error Subsequent to the issuance of the condensed consolidated financial statements as of and for the three months ended September 30, 2015, the Company determined installation revenue and related cost of revenue was being deferred and recognized over the contractual life for certain contracts that should have been recognized over the customer life. Accordingly, the accompanying condensed consolidated financial statements reflect the Company’s correction of the condensed consolidated statement of operations impact of the error for the three and nine months ended March 31, 2015, the nine months ended March 31, 2016 and the condensed consolidated balance sheet impact as of June 30, 2015. As a result, hosted and related services revenue and cost of revenue were decreased by $0.3 million and $0.8 million for the three and nine months ended March 31, 2015, respectively. Hosted and related services revenue and cost of revenue were decreased by $0.1 million for the nine months ended March 31, 2016. Prepaid expense and other current assets was increased by $2.7 million, other assets was increased by $1.2 million, deferred revenue was increased by $1.0 million and long-term deferred revenue was increased by $3.0 million as of June 30, 2015. The cumulative impact of the correction on preceding period earnings is an increase to accumulated deficit of $0.1 million as of June 30, 2015. The correction did not affect the net cash provided by operating activities, net cash used in investing activities or net cash provided by financing activities for the nine months ended March 31, 2016 and 2015. The correction did not affect the net loss per share for the three and nine months ended March 31, 2015 or the nine months ended March 31, 2016. The foregoing corrections are not considered material by the Company. Computation of Net Income (Loss) per Share Basic net income per share is determined by dividing net income by the weighted average number of common shares outstanding during the period. Diluted net income per share is determined by dividing net income by the weighted average number of common shares used in the basic income per share calculation plus the number of common shares that would be issued assuming conversion of all potentially dilutive securities outstanding under the treasury stock method. Dilutive securities of 3.4 million weighted shares and 5.3 million weighted shares were not included in the computation of diluted net income per share for the three and nine months ended March 31, 2016, respectively because such securities were anti-dilutive. Dilutive securities of 4.1 million weighted shares and 3.8 million weighted shares were not included in the computation of diluted net loss per share for the three and nine months ended March 31, 2015, respectively because such securities were anti-dilutive. Concentration of Credit Risk Financial instruments, which potentially subject the Company to concentrations of credit risk, consist principally of cash, cash equivalents, short-term investments and accounts receivable. As of March 31, 2016, all of the Company’s cash, cash equivalents and short-term investments were managed by several financial institutions. Accounts receivable are typically unsecured and are derived from revenue earned from customers. The Company performs ongoing credit evaluations of its customers and maintains allowances for potential credit losses. At June 30, 2015 the same value-added distributor accounted for 33% of the total accounts receivable Significant Accounting Policies The Company’s significant accounting policies are included in the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2015.

Business Combinations [Abstract]
Business Combinations	3. Business Combinations M5 Networks Australia Pty Ltd Acquisition On November 16, 2015, the Company acquired all of the outstanding common stock of M5 Networks Australia Pty Ltd. (“M5 Australia”), a privately-held company based in Australia and a provider of hosted unified communications solutions, for total cash consideration of $6.1 million (8.5 million Australian dollars). The acquisition accelerates the Company’s growth and expansion of providing hosted unified communications services in Australia. In accordance with ASC 805, Business Combinations Preliminary Purchase Price Allocation The total purchase price was preliminarily allocated to M5 Australia’s net tangible and identifiable intangible assets based on their estimated fair values as of November 16, 2015 as set forth below. The primary areas of the purchase price allocation that are not yet finalized relate to deferred taxes and goodwill. The following is the preliminary purchase price allocation (in thousands): Estimated useful lives Cash acquired $ 224 Other current assets 386 Intangible assets: Customer relationships 1,300 5 Goodwill 5,210 Other long-term assets 164 Other liabilities assumed (1,174 ) $ 6,110 Valuing certain components of the acquisition, including intangible assets required the Company to make estimates that may be adjusted in the future, if new information is obtained about facts and circumstances that existed as of the acquisition date that, if known, would have resulted in the recognition of those assets and liabilities as of that date. Consequently, the purchase price allocation is considered preliminary. Final determination of these estimates could result in an adjustment to the preliminary purchase price allocation, with an offsetting adjustment to goodwill. Measurement period adjustments will be recorded in the period in which the adjustment amounts are determined. The Company recorded $0.1 million and $0.3 million for legal, accounting, consulting and other costs directly related to the acquisition as acquisition-related costs during the three and nine months ended March 31, 2016, respectively. The results of operations of M5 Australia have been included in the Company's consolidated statements of operations from the acquisition date, though revenue and gross margin from M5 Australia were not material for the three and nine months March 31, 2016. Due to the continued integration of the combined business, it is impractical to determine the earnings from M5 Australia beyond the measure of gross profit. Corvisa LLC Acquisition On January 6, 2016, the Company acquired all of the outstanding membership interest in Corvisa LLC (“Corvisa”), a provider of cloud-based communications solutions, for total cash consideration of $8.7 million. The acquisition accelerates the Company’s growth and expansion of its hosted unified communications service offering. In accordance with ASC 805, Business Combinations The fair value of purchased identifiable intangible assets was derived from model-based valuations from significant unobservable inputs (“Level 3 inputs”) determined by management. The fair value of purchased identifiable intangible assets was determined using the Company’s discounted cash flow models from operating projections prepared by management using a market participant rate of 35.0%. The total purchase price was preliminarily allocated to Corvisa’s net tangible and identifiable intangible assets based on their estimated fair values as of January 6, 2016 as set forth below. The primary areas of the purchase price allocation that are not yet finalized relate to property and equipment, contingency accruals, deferred taxes and goodwill. The following is the preliminary purchase price allocation (in thousands): (in thousands) Estimated useful lives Cash acquired $ 227 Other current assets 933 Intangible assets: Existing technology 3,400 5 Customer relationships 100 3 Favorable leases 178 6 Goodwill 1,489 Other long-term assets 3,301 Other liabilities assumed (966 ) $ 8,662 Valuing certain components of the acquisition, including intangible assets required us to make estimates that may be adjusted in the future, if new information is obtained about facts and circumstances that existed as of the acquisition date that, if known, would have resulted in the recognition of those assets and liabilities as of that date. Consequently, the purchase price allocation is considered preliminary. Final determination of these estimates could result in an adjustment to the preliminary purchase price allocation, with an offsetting adjustment to goodwill. Measurement period adjustments will be recorded in the period in which the adjustment amounts are determined. The Company recorded $0.7 million and $1.1 million for legal, accounting, consulting and other costs directly related to the acquisition as acquisition-related costs during the three and nine months ended March 31, 2016, respectively. The results of operations of Corvisa have been included in the Company's consolidated statements of operations from the acquisition date, though revenue and gross margin from Corvisa were not material for the three and nine months March 31, 2016. Due to the continued integration of the combined business, it is impractical to determine the earnings from Corvisa beyond the measure of gross profit. The unaudited pro forma financial information in the table below summarizes the combined results of operations for the Company and its Corvisa acquisition as though Corvisa was combined as of the beginning of fiscal 2015. The pro forma financial information for the period presented also includes the business combination accounting effects resulting from the acquisition primarily related to amortization charges from acquired intangible assets. The pro forma financial information below is also adjusted to exclude the Company’s non-recurring acquisition-related costs of $0.7 million and $1.1 million incurred in the three and nine months ended March 31, 2016, respectively, and included the year to date total in the nine months ended March 31, 2015. The pro forma financial information as presented below is for informational purposes only and is not indicative of the results of operations that would have been achieved if the Corvisa acquisition had taken place at the beginning of fiscal 2015.

Fair Value Disclosure Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in the principal market (or most advantageous market, in the absence of a principal market) for the asset or liability in an orderly transaction between market participants at the measurement date. Further, entities are required to maximize the use of observable inputs and minimize the use of unobservable inputs in measuring fair value, and to utilize a three-level fair value hierarchy that prioritizes the inputs used to measure fair value. The three levels of inputs used to measure fair value are as follows: • Level 1 — Quoted prices in active markets for identical assets or liabilities. • Level 2 — Observable inputs other than quoted prices included within Level 1, including quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; and inputs other than quoted prices that are observable or are derived principally from, or corroborated by, observable market data by correlation or other means. • Level 3 — Unobservable inputs that are supported by little or no market activity, are significant to the fair value of the assets or liabilities, and reflect the Company’s own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. The tables below set forth the Company’s financial instruments and liabilities measured at fair value on a recurring basis (in thousands): March 31, 2016 Fair Value Level 1 Level 2 Level 3 Assets: Cash and cash equivalents: Money market funds $ 36,709 $ 36,709 $ - $ - Short-term investments: Corporate notes and commercial paper 10,517 - 10,517 - U.S. Government agency securities 2,752 - 2,752 - Total assets measured and recorded at fair value $ 49,978 $ 36,709 $ 13,269 $ - The above table excludes $50.1 million of cash balances on deposit at banks. June 30, 2015 Fair Value Level 1 Level 2 Level 3 Assets: Cash and cash equivalents: Money market funds $ 4,025 $ 4,025 $ - $ - Short-term investments: Corporate notes and commercial paper 8,025 - 8,025 - Total assets measured and recorded at fair value $ 12,050 $ 4,025 $ 8,025 $ - The above table excludes $78.1 million of cash balances on deposit at banks. Money market funds are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices in active markets. Short-term investments are classified within Level 2 of the fair value hierarchy because they are valued based on other observable inputs, including broker or dealer quotations, or alternative pricing sources. When quoted prices in active markets for identical assets or liabilities are not available, the Company relies on non-binding quotes from independent pricing services. Non-binding quotes are based on proprietary valuation models prepared by independent pricing services. These models use algorithms based on inputs such as observable market data, quoted market prices for similar instruments, historical pricing trends of a security as relative to its peers, internal assumptions of the independent pricing service and statistically supported models. The Company corroborates the reasonableness of non-binding quotes received from the independent pricing service by comparing them to the (a) actual experience gained from the purchases and redemption of investment securities, (b) quotes received on similar securities obtained when purchasing securities and (c) monitoring changes in ratings of similar securities and the related impact on the fair value. The types of instruments valued based on other observable inputs include corporate notes and commercial paper and U.S. Government agency securities. The Company reviewed financial and non-financial assets and liabilities and concluded that there were no other-than-temporary impairment charges during the three and nine months ended March 31, 2016 and 2015, respectively. The Company reviews the fair value hierarchy on a quarterly basis. Changes in the ability to observe valuation inputs may result in a reclassification of levels of certain securities within the fair value hierarchy. The Company recognizes transfers into and out of levels within the fair Assets and Liabilities That Are Measured at Fair Value on a Nonrecurring Basis Non-financial assets such as goodwill, intangible assets, and property, plant, and equipment are evaluated for impairment and adjusted to fair value using Level 3 inputs, only when impairment is recognized. Fair values are considered Level 3 when management makes significant assumptions in developing a discounted cash flow model based upon a number of considerations including projections of revenues, earnings and a discount rate. In addition, in evaluating the fair value of goodwill impairment, further corroboration is obtained using the Company’s market capitalization. There were no indicators of impairment in the three and nine months ended March 31, 2016 that required a nonrecurring fair value analysis to be performed on non-financial assets.

Line of Credit [Abstract]
Line of Credit	6. Line of Credit On October 22, 2014 the Company entered into an Amended and Restated Credit Agreement which was further amended on December 1, 2014 and again on August 5, 2015 . The New Credit Facility contains customary affirmative and negative covenants, including compliance with financial ratios and metrics. The New Credit Facility and the related amendment requires the Company to maintain a minimum ratio of liquidity to its indebtedness (each as defined in the New Credit Facility) and varying amounts of Liquidity and Consolidated EBITDA specified in the New Credit Facility throughout the term of the agreement. The Company was in compliance with all such covenants as of March 31, 2016. As of March 31, 2016, no amounts were outstanding under the New Credit Facility. The Company amortizes deferred financing costs to interest expense on a straight-line basis over the term of the New Credit Facility.

Income Taxes [Abstract]
Income Taxes	7. Income Taxes The Company recorded an income tax benefit of $0.3 million and $36,000 for the three months ended March 31, 2016 and 2015, respectively and an income tax provision of $0.5 million for both the nine months ended March 31, 2016 and 2015. These income tax benefits and provisions are primarily comprised of United States federal alternative minimum tax, state taxes and foreign income taxes. No income tax benefit was accrued for jurisdictions where the Company anticipates incurring a loss during the full fiscal year as the related deferred tax assets were fully offset by a valuation allowance. The Company’s resulting effective tax rate differs from the applicable statutory rate primarily due to the valuation allowance against its deferred tax assets in select jurisdictions . The Company maintains liabilities for uncertain tax positions. As of March 31, 2016 and June 30, 2015, the Company’s total amount of unrecognized tax benefits was $5.3 million and $5.1 million, respectively. Of the total of $5.3 million of unrecognized tax benefit as of March 31, 2016, none, if recognized, would impact the effective tax rate. The Company does not expect its unrecognized tax benefits to change materially over the next 12 months. While management believes that the Company has adequately provided for all tax positions, amounts asserted by tax authorities could be greater or less than the Company’s current position. Accordingly, the Company’s provisions for federal, state and foreign tax related matters to be recorded in the future may change as revised estimates are made or as the underlying matters are settled or otherwise resolved. The Company’s primary tax jurisdiction is in the United States. For federal and state tax purposes, the tax years 2002 through 2014 remain open and subject to tax examination by the appropriate federal or state taxing authorities. The Protecting Americans from Tax Hikes (PATH) Act (“Act”) was signed into law on December 18, 2015. The Act contains a number of provisions including, most notably, permanent extension of the United States federal research tax credit. The Act did not have a material impact on our effective tax rate for fiscal 2016 due to the effect of the valuation allowance on the Company's deferred tax assets.

This cost will be amortized on a ratable basis over a weighted-average vesting period of approximately 2.8 years.

Derivative Instruments and Hedging Activities [Abstract]
Derivative Instruments and Hedging Activities	15. Derivative Instruments and Hedging Activities In the normal course of business, the Company is exposed to fluctuations in interest rates and the exchange rates associated with foreign currencies. During the three and nine months ended March 31, 2016, the Company used derivative instruments to reduce the volatility of earnings associated with changes in foreign currency exchange rates. The Company used foreign exchange forward contracts to mitigate the gains and losses generated from the re-measurement of certain foreign monetary assets and liabilities, primarily including cash balances, third party accounts receivable and intercompany transactions recorded on the balance sheet. These derivatives are not designated and do not qualify as hedge instruments. Accordingly, changes in the fair value of these instruments are recognized in other income and expenses during the period of change. These derivatives have maturities of approximately one month. The foreign exchange forward contracts outstanding as of March 31, 2016 were entered into by the Company on the last business day of the period. Given the relatively short duration such contracts are outstanding in relation to changes in potential market rates; the change in the fair value is not material and is not reflected either as an asset or a liability. The following table presents the gross notional value of all of the Company’s foreign exchange forward contracts outstanding as of March 31, 2016 and June 30, 2015 (in thousands): March 31, 2016 Local Currency Amount Notional Contract Amount (USD) Australian dollar $ 2,200 $ 1,673 British pound £ 1,300 $ 1,861 Canadian dollar $ 870 $ 665 Euro € 1,440 $ 1,628 Total $ 5,827 June 30, 2015 Local Currency Amount Notional Contract Amount (USD) Australian dollar $ 2,420 $ 1,840 British pound £ 910 1,429 Canadian dollar $ 750 596 Euro € 1,550 1,708 Total $ 5,573

Correction of Prior Period Error	Correction of Prior Period Error Subsequent to the issuance of the condensed consolidated financial statements as of and for the three months ended September 30, 2015, the Company determined installation revenue and related cost of revenue was being deferred and recognized over the contractual life for certain contracts that should have been recognized over the customer life. Accordingly, the accompanying condensed consolidated financial statements reflect the Company’s correction of the condensed consolidated statement of operations impact of the error for the three and nine months ended March 31, 2015, the nine months ended March 31, 2016 and the condensed consolidated balance sheet impact as of June 30, 2015. As a result, hosted and related services revenue and cost of revenue were decreased by $0.3 million and $0.8 million for the three and nine months ended March 31, 2015, respectively. Hosted and related services revenue and cost of revenue were decreased by $0.1 million for the nine months ended March 31, 2016. Prepaid expense and other current assets was increased by $2.7 million, other assets was increased by $1.2 million, deferred revenue was increased by $1.0 million and long-term deferred revenue was increased by $3.0 million as of June 30, 2015. The cumulative impact of the correction on preceding period earnings is an increase to accumulated deficit of $0.1 million as of June 30, 2015. The correction did not affect the net cash provided by operating activities, net cash used in investing activities or net cash provided by financing activities for the nine months ended March 31, 2016 and 2015. The correction did not affect the net loss per share for the three and nine months ended March 31, 2015 or the nine months ended March 31, 2016. The foregoing corrections are not considered material by the Company.
Computation of Net Income (Loss) per Share	Computation of Net Income (Loss) per Share Basic net income per share is determined by dividing net income by the weighted average number of common shares outstanding during the period. Diluted net income per share is determined by dividing net income by the weighted average number of common shares used in the basic income per share calculation plus the number of common shares that would be issued assuming conversion of all potentially dilutive securities outstanding under the treasury stock method. Dilutive securities of 3.4 million weighted shares and 5.3 million weighted shares were not included in the computation of diluted net income per share for the three and nine months ended March 31, 2016, respectively because such securities were anti-dilutive. Dilutive securities of 4.1 million weighted shares and 3.8 million weighted shares were not included in the computation of diluted net loss per share for the three and nine months ended March 31, 2015, respectively because such securities were anti-dilutive.
Concentration of Credit Risk	Concentration of Credit Risk Financial instruments, which potentially subject the Company to concentrations of credit risk, consist principally of cash, cash equivalents, short-term investments and accounts receivable. As of March 31, 2016, all of the Company’s cash, cash equivalents and short-term investments were managed by several financial institutions. Accounts receivable are typically unsecured and are derived from revenue earned from customers. The Company performs ongoing credit evaluations of its customers and maintains allowances for potential credit losses. At June 30, 2015 the same value-added distributor accounted for 33% of the total accounts receivable
