Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies Radisys Corporation (the “Company” or “Radisys”) has adhered to the accounting policies set forth in its Annual Report on Form 10-K for the year ended December 31, 2014 in preparing the accompanying interim condensed consolidated financial statements. The preparation of these statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosure of contingent assets and liabilities. Actual results could differ from those estimates. Additionally, the accompanying financial data as of September 30, 2015 and for the three and nine months ended September 30, 2015 and 2014 has 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 GAAP have been 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 year ended December 31, 2014 . Certain prior year balances have been reclassified to conform to the current year’s presentation. Such reclassifications did not affect total cash flows, total net revenues, operating loss, net loss, total assets, total liabilities or shareholders’ equity. The financial information included herein reflects all normal recurring adjustments that are, in the opinion of management, necessary for a fair presentation of the results for interim periods.

Fair Value Disclosures [Abstract]
Fair Value Disclosures	Fair Value of Financial Instruments Assets and Liabilities Measured at Fair Value on a Recurring Basis The Company measures at fair value certain financial assets and liabilities. GAAP specifies a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company's market assumptions. These two types of inputs have created the following fair-value hierarchy: Level 1— Quoted prices for identical instruments in active markets; Level 2— Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets; and Level 3— Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. Foreign currency forward contracts are measured at fair value using models based on observable market inputs such as foreign currency exchange rates; therefore, they are classified within Level 2 of the valuation hierarchy. The following table summarizes the fair value measurements for the Company's financial instruments (in thousands): Fair Value Measurements as of September 30, 2015 Total Level 1 Level 2 Level 3 Foreign currency forward contracts $ (343 ) — $ (343 ) — Fair Value Measurements as of December 31, 2014 Total Level 1 Level 2 Level 3 Foreign currency forward contracts $ (83 ) — $ (83 ) —

Short-term Debt [Abstract]
Short-term Debt	Short-Term Borrowings Silicon Valley Bank On March 14, 2014, the Company entered into an amended and restated $25.0 million revolving line of credit agreement with Silicon Valley Bank ("SVB") (as amended, the "2014 Agreement") which has a stated maturity date of July 28, 2016. On May 30, 2014, the 2014 Agreement was amended to increase the letter of credit sublimit under the secured revolving credit facility from $1,000,000 to $2,000,000 or the net borrowing availability. On April 23, 2015, the 2014 Agreement was amended to further increase the letter of credit sublimit under the secured revolving credit facility from $2,000,000 to $5,000,000 or the net borrowing availability. The secured revolving credit facility under the 2014 Agreement is available for cash borrowings and is subject to a borrowing formula based upon eligible accounts receivable less outstanding letters of credit (aggregate letters of credit are not to exceed $5,000,000 ). Eligible accounts receivable include 80% of U.S. and 65% of foreign accounts receivable (80% in certain cases), not greater than 60 days past original invoice date. The interest rate is dependent upon the Company's Liquidity (as defined in the 2014 Agreement) when compared to a pre-determined threshold (the "Liquidity Threshold"), which is defined in the 2014 Agreement as $15.0 million , with the exception of the last month end of each quarter, where it is defined as $20.0 million . Liquidity is calculated under the 2014 Agreement as unrestricted cash plus unused availability on the revolving line of credit reduced by the outstanding principal amount of the 2015 convertible senior notes. The calculation of interest under the 2014 Agreement is as follows: • When Liquidity is above the Liquidity Threshold, the interest rate is the prime rate (as published in Wall Street Journal) plus 0.75% ; and • When Liquidity is below the Liquidity Threshold, the interest rate is the prime rate (as published in Wall Street Journal) plus 2.25% . Under the 2014 Agreement, the Company is required to make interest payments monthly. The Company was further required to pay a loan modification fee of $35,000 and a commitment fee equal to $35,000 on July 29, 2014 and will be required to pay the commitment fee annually thereafter. Under the 2014 Agreement the Company is required to pay the higher of actual monthly interest incurred or the interest equivalent of $10.0 million in average monthly borrowings. If the Company terminates the commitment under the 2014 Agreement prior to the maturity date, the Company is required to pay a cancellation fee equal to 1.5% of the commitment under the 2014 Agreement. As of September 1, 2014, and at all times thereafter, the Company is required to maintain a deposit account balance of at least $4,000,000 million with SVB or its affiliates and the Company is required to have at least 50% of its cash deposited with SVB or its affiliates or in an account where SVB has a control agreement. The 2014 Agreement requires the Company to make certain representations, warranties and other agreements that are customary in credit agreements of this type. The 2014 Agreement also includes a financial covenant that requires the Company to maintain minimum Liquidity of $10.0 million tested monthly. As of September 30, 2015 and December 31, 2014 , the Company had an outstanding balance of $10.0 million under the 2014 Agreement. At September 30, 2015 , the Company had $13.5 million of total borrowing availability remaining under the 2014 Agreement. At September 30, 2015 , the Company was in compliance with all covenants under the 2014 Agreement.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies Disclosure	Commitments and Contingencies Adverse Purchase Commitments The Company is contractually obligated to reimburse its contract manufacturer for the cost of excess inventory used in the manufacture of the Company's products if there is no alternative use. Estimates for adverse purchase commitments are derived from reports received on a quarterly basis from the Company's contract manufacturer. Increases to this liability are charged to cost of sales. If and when the Company takes possession of inventory reserved for in this liability, the liability is transferred from other accrued liabilities to the excess and obsolete inventory valuation allowance (Note 4 — Inventories ). The adverse purchase commitment liability is included in other accrued liabilities in the accompanying Condensed Consolidated Balance Sheets and was $2.1 million and $1.7 million as of September 30, 2015 and December 31, 2014 . Guarantees and Indemnification Obligations As permitted under Oregon law, the Company has agreements whereby it indemnifies its officers, directors and certain finance employees for certain events or occurrences while an officer, director or employee is or was serving in such capacity at the request of the Company. The term of the indemnification period is for the officer's, director's or employee's lifetime. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is unlimited; however, the Company has a Director and Officer insurance policy that limits its exposure and enables the Company to recover a portion of any future amounts paid. To date, the Company has not incurred any costs associated with these indemnification agreements and, as a result, management believes the estimated fair value of these indemnification agreements is minimal. Accordingly, the Company has not recorded any liabilities for these agreements as of September 30, 2015 . The Company enters into standard indemnification agreements in its ordinary course of business. Pursuant to these agreements, the Company indemnifies, holds harmless, and agrees to reimburse the indemnified party for losses suffered or incurred by the indemnified party, generally the Company's business partners or customers, in connection with patent, copyright or other intellectual property infringement claims by any third party with respect to the Company's current products, as well as claims relating to property damage or personal injury resulting from the performance of services by us or the Company's subcontractors. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is generally limited. Historically, the Company's costs to defend lawsuits or settle claims relating to such indemnity agreements have been minimal. Accrued Warranty The Company provides for the estimated cost of product warranties at the time it recognizes revenue. Products are generally sold with warranty coverage for a period of 12 or 24 months after shipment. Parts and labor are covered under the terms of the warranty agreement. The workmanship of the Company’s products produced by the contract manufacturer is covered under warranties provided by the contract manufacturer for 12 to 24 months. The warranty provision is based on historical experience by product family. The Company engages in extensive product quality programs and processes, including actively monitoring and evaluating the quality of its components suppliers; however ongoing failure rates, material usage and service delivery costs incurred in correcting product failure, as well as specific product class failures out of the Company’s baseline experience, affect the estimated warranty obligation. If actual product failure rates, material usage or service delivery costs differ from estimates, revisions to the estimated warranty liability would be required. The following is a summary of the change in the Company's warranty accrual reserve (in thousands): Nine Months Ended September 30, 2015 2014 Warranty liability balance, beginning of the period $ 2,600 $ 3,328 Product warranty accruals 1,607 1,843 Utilization of accrual (1,593 ) (2,480 ) Warranty liability balance, end of the period $ 2,614 $ 2,691 At September 30, 2015 and December 31, 2014 , $2.1 million and $2.0 million of the warranty liability balance was included in other accrued liabilities and $0.5 million and $0.6 million was included in other long-term liabilities in the accompanying Condensed Consolidated Balance Sheets.

Income Tax Disclosure [Abstract]
Income Tax Disclosure	Income Taxes The Company's effective tax rate for the three months ended September 30, 2015 differs from the statutory rate due to a full valuation allowance provided against its United States (“U.S.”) net deferred tax assets, and taxes on foreign income that differ from the U.S. tax rate. The Company utilizes the asset and liability method of accounting for income taxes. The Company records deferred tax assets to the extent it believes these assets will more likely than not be realized. In making such determination, the Company considers all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies, and recent financial performance. Based upon the Company's review of all positive and negative evidence, including its three year U.S. cumulative pre-tax book loss and taxable loss, it concluded that a full and a partial valuation allowance should continue to be recorded against its U.S. and Canadian net deferred tax assets at September 30, 2015 . In certain other foreign jurisdictions, where the Company does not have cumulative losses or other negative evidence, the Company had net deferred tax assets of $0.9 million and $1.1 million at September 30, 2015 and December 31, 2014 . In the future, if the Company determines that it is more likely than not that it will realize its U.S. and Canadian net deferred tax assets, it will reverse the applicable portion of the valuation allowance and recognize an income tax benefit in the period in which such determination is made. The ending balance for the unrecognized tax benefits was approximately $3.7 million at September 30, 2015 . The related interest and penalties were $0.6 million and $0.3 million . The uncertain tax positions that are reasonably possible to decrease in the next twelve months are insignificant. The Company is currently under tax examination in India. The periods covered under examination are the Company's financial years 2006 through 2008 and 2010 through 2012. The examination is in various stages of appellate proceedings and all material uncertain tax positions associated with the examination have been taken into account in the ending balance of the unrecognized tax benefits at September 30, 2015 . As of September 30, 2015 , the Company is not under examination by tax authorities in any other jurisdictions.

If either of the stock price hurdles is not met during their respective performance period, that portion of the award will be forfeited. In 2014, the performance based restricted stock awards were presented based on attainment of 100% of the performance goals being met. These awards provided for the grants of awards payable in shares of common stock upon the achievement of performance goals set by the Company's Compensation and Development Committee. In addition to the performance conditions, the awards contained market-based multipliers based on the average price of the Company's common stock thirty days prior to the end of each semi-annual performance period. The maximum multiplier for a given semi-annual performance period was 2.75 x the original grant and overall achievement was limited to a maximum of 2.5 x of the target award over the entire performance period.

Hedging

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities Disclosure [Text Block]	Hedging The Company’s activities expose it to a variety of market risks, including the effects of changes in foreign currency exchange rates. The Company manages these risks through the use of forward exchange contracts, designated as foreign-currency cash flow hedges, in an attempt to reduce the potentially adverse effects of foreign currency exchange rate fluctuations that occur in the normal course of business. As such, the Company’s hedging activities are employed solely for risk management purposes. All hedging transactions are conducted with, in the opinion of management, financially stable and reputable financial institutions. As of September 30, 2015 and December 31, 2014 , the only hedge instruments executed by the Company are associated with its exposure to fluctuations in the Indian Rupee, which result from obligations such as payroll and rent paid in this currency. These derivatives are recognized on the balance sheet at their fair value. Unrealized gain positions are recorded as other current assets and unrealized loss positions are recorded as other current liabilities. Changes in the fair values of the outstanding derivatives that are highly effective are recorded in other comprehensive income until net income (loss) is affected by the variability of the cash flows of the hedged transaction. Typically, hedge ineffectiveness could result when the amount of the Company’s hedge contracts exceed the Company’s forecasted or actual transactions for which the hedge contracts were designed to hedge. Once a hedge contract matures, the associated gain (loss) on the contract will remain in other comprehensive income (loss) until the underlying hedged transaction affects net income (loss), at which time the gain (loss) will be reclassified out of accumulated other comprehensive income (loss) and recorded to the expense line item being hedged. The Company only enters into derivative contracts in order to hedge foreign currency exposure, and these contracts do not exceed two years from inception. If the Company entered into a contract for speculative reasons or if the Company’s current hedge position becomes ineffective, changes in the fair values of the derivatives would be recognized in earnings in the current period. The Company assesses, both at the inception of the hedge and on an ongoing basis, whether the derivatives that are used in hedging transactions have been highly effective in offsetting changes in the cash flows of hedged items and whether those derivatives are expected to remain highly effective in future periods. For the three and nine months ended September 30, 2015 and 2014 , the Company had no hedge ineffectiveness. During the three and nine months ended September 30, 2015 the Company entered into 16 new foreign currency forward contracts, with total contractual values of $7.5 million . During the three and nine months ended September 30, 2014 , the Company entered into 18 new foreign currency forward contracts with a notional value of $11.6 million . A summary of the aggregate contractual or notional amounts, balance sheet location and estimated fair values of derivative financial instruments designated as cash flow hedges at September 30, 2015 is as follows (in thousands): Contractual/ Notional Amount Condensed Consolidated Balance Sheet Classification Estimated Fair Value Type of Cash Flow Hedge Asset (Liability) Foreign currency forward exchange contracts $ 12,441 Other accrued liabilities $ — $ (343 ) A summary of the aggregate contractual or notional amounts, balance sheet location and estimated fair values of derivative financial instruments designated as cash flow hedges at December 31, 2014 is as follows (in thousands): Contractual/ Notional Amount Condensed Consolidated Balance Sheet Classification Estimated Fair Value Type of Cash Flow Hedge Asset (Liability) Foreign currency forward exchange contracts $ 14,193 Other accrued liabilities $ — $ (83 ) There were no ineffective hedges for the three and nine months ended September 30, 2015 and 2014.

The bank counterparties in these contracts expose the Company to credit-related losses in the event of their nonperformance. However, to mitigate that risk, the Company only contracts with counterparties who meet its minimum requirements regarding counterparty credit worthiness. In addition, the Company monitors credit ratings, credit spreads and potential downgrades prior to entering into any new hedging contracts.
