Organization, Business and Summary of Significant Accounting Policies	'
	ANIZATION, BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	Company Background
	Prior to October 31, 2012, the date of the Share Distribution (as defined below), Comverse, Inc. (the “Company”) was a wholly-owned subsidiary of Comverse Technology, Inc. (“CTI”). The Company was organized as a Delaware corporation in November 1997.
	The Company is a leading provider of telecom business enablement solutions for communication service providers (“CSPs”) through a portfolio of product-based solutions and associated services in the following domains:
	•	Business Support Systems. The Company provides converged, prepaid and postpaid billing and active customer management systems (“BSS”) for wireless, wireline and cable CSPs, delivering a value proposition designed to enable an effective service monetization, a consistent customer experience, reduced complexity and cost, and real-time choice and control.
	•	Digital and Value Added Services. The Company enables both network-based Value Added Services (“VAS”) comprised of Voice and Messaging that include voicemail, visual voicemail, call completion, short messaging service ("SMS"), multimedia picture and video messaging ("MMS"), and digital Internet Protocol ("IP") based rich communication services.
	•	Data Management and Monetization Solutions. The Company provides CSPs with the ability to better manage their data networks and better monetize their data network investment through its solutions' Policy Management and Policy Enforcement capabilities for wireless and wireline data networks.
	•	Professional and Managed Services. The Company offers a portfolio of services related to its solutions following the completion of the delivery of the project to the customer ("post-go-live"), such as system care, expert services and managed services.
	The Share Distribution
	On October 31, 2012, CTI completed its spin-off of the Company as an independent, publicly-traded company, accomplished by means of a pro rata distribution of 100% of the Company's outstanding common shares to CTI's shareholders (the “Share Distribution”). Following the Share Distribution, CTI no longer holds any of the Company's outstanding capital stock, and the Company is an independent publicly-traded company.
	Immediately prior to the Share Distribution, CTI contributed to the Company Exalink Ltd. (“Exalink”), CTI's wholly-owned subsidiary. Other than holding certain intellectual property rights, Exalink has no operations. Following the Share Distribution, the Company and CTI operate independently, and neither had any ownership interest in the other. In order to govern certain ongoing relationships between CTI and the Company after the Share Distribution and to provide mechanisms for an orderly transition, CTI and the Company entered into agreements pursuant to which certain services and rights are provided for following the Share Distribution, and CTI and the Company have agreed to indemnify each other against certain liabilities arising from their respective businesses and the services that are provided under such agreements. Following the completion of CTI's merger with Verint Systems Inc. ("Verint") discussed below, these obligations continue to apply between the Company and Verint (see Note 3, Expense Allocations and Share Distribution Agreements).
	Upon completion of the Share Distribution, the Company's shares were listed, and began trading, on NASDAQ under the symbol “CNSI.” In connection with the Share Distribution, the Company (1) recapitalized its Net Investment of CTI with its common stock, whereby each holder of CTI common shares outstanding as of the record date for the Share Distribution received one share of the Company's common stock for every ten CTI common shares held thereby, which resulted in the issuance of approximately 21.9 million shares of the Company's common stock, (2) received contributions from CTI of $38.5 million in cash and $1.4 million of property and equipment based on CTI's book value, (3) recorded transfers of lease deposits of $0.8 million and deferred lease cost of $1.0 million from CTI, (4) assumed $0.7 million of employee related liabilities transferred to the Company from CTI, and (5) settled borrowings under a revolving loan agreement of $9.0 million and note payable by the Company to CTI of $9.4 million through a capital contribution to the Company's equity by CTI. In addition on November 1, 2012 in connection with the Share Distribution, CTI's equity-based compensation awards held by the Company's employees were replaced with the Company's equity-based compensation awards (see Note 13, Stock-Based Compensation).
	Merger of CTI and Verint
	On August 12, 2012, CTI entered into an agreement and plan of merger (the “Verint Merger Agreement”) with Verint, its then majority-owned publicly-traded subsidiary, providing for the merger of CTI with and into a subsidiary of Verint to become a wholly-owned subsidiary of Verint (the “Verint Merger”). The Verint Merger was completed on February 4, 2013. The Company agreed to indemnify CTI and its affiliates (including Verint after the Verint Merger) against certain losses that may arise as a result of the Verint Merger and the Share Distribution (see Note 3, Expense Allocations and Share Distribution Agreements). On February 4, 2013, in connection with the closing of the Verint Merger Agreement, CTI placed $25.0 million in escrow to support indemnification claims to the extent made against the Company by Verint and any cash balance remaining in such escrow fund 18 months after the closing of the Verint Merger, less any claims made on or prior to such date, will be released to the Company. The Company recognized the estimated fair value of the potential indemnification liability of $4.0 million with the remaining $21.0 million as an additional contribution from CTI. As of October 31, 2013, the estimated fair value of the potential indemnification liability is $4.0 million.
	Contribution and Sale of Starhome
	Starhome was a CTI Subsidiary (66.5% owned as of January 31, 2012). On August 1, 2012, CTI, certain other Starhome shareholders and Starhome entered into a Share Purchase Agreement (the “Starhome Share Purchase Agreement”) with Fortissimo Capital Fund II (Israel), L.P., Fortissimo Capital Fund III (Israel), L.P. and Fortissimo Capital Fund III (Cayman), L.P. (collectively, “Fortissimo”) pursuant to which Fortissimo agreed to purchase all of the outstanding share capital of Starhome (the “Starhome Disposition”). On September 19, 2012, CTI, in order to ensure it could meet the conditions of the Verint Merger, contributed to the Company its interest in Starhome, including its rights and obligations under the Starhome Share Purchase Agreement. The Starhome Disposition was completed on October 19, 2012.
	As a result of the Starhome Disposition, the results of operations of Starhome are included in discontinued operations, less applicable income taxes, as a separate component of net income (loss) in the Company’s condensed combined statements of operations for the three and nine months ended October 31, 2012 (see Note 14, Discontinued Operations).
	Basis of Presentation
	The condensed consolidated and combined financial statements included herein have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and on the same basis as the audited consolidated and combined financial statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended January 31, 2013 (the “2012 Form 10-K”).
	The condensed consolidated and combined statements of operations, comprehensive income (loss) and cash flows for the periods ended October 31, 2013 and 2012, and the condensed consolidated balance sheet as of October 31, 2013 are not audited but in the opinion of management reflect all adjustments that are of a normal recurring nature and that are considered necessary for a fair presentation of the results of the periods presented. Certain information and disclosures normally included in audited financial statements have been omitted in these condensed consolidated and combined financial statements pursuant to the rules and regulations of the SEC. Because the condensed consolidated and combined financial statements do not include all of the information and disclosures required by U.S. GAAP for annual financial statements, they should be read in conjunction with the audited consolidated and combined financial statements and notes included in the 2012 Form 10-K. The results for the three and nine months ended October 31, 2013 are not necessarily indicative of a full fiscal year’s results.
	The Company’s combined financial statements for the periods prior to the Share Distribution have been derived from the condensed consolidated financial statements and accounting records of CTI, using the historical results of operations, and historical basis of assets and liabilities of the Company’s businesses, which operated under common control of CTI. The Company’s condensed combined financial statements combine, on the basis of common control, the results of operations and financial position of the Company and its subsidiaries with Starhome (66.5% owned by CTI as of January 31, 2012) and Exalink prior to CTI contributing Starhome and Exalink to the Company on September 19, 2012 and October 31, 2012, respectively. Management believes the assumptions and methodologies underlying the allocation of general corporate expenses from CTI are reasonable (see Note 3, Expense Allocations and Share Distribution Agreements). However, such expenses may not be indicative of the actual level of expense that would have been incurred by the Company if it had operated as an independent, publicly-traded company or of the costs expected to be incurred in the future. As such, the condensed combined financial statements for the periods prior to the Share Distribution included herein may not necessarily reflect the Company’s results of operations, comprehensive income (loss), financial position or cash flows in the future or what its results of operations, comprehensive income (loss), financial position or cash flows would have been had the Company been an independent company during the prior periods presented. Subsequent to the Share Distribution, the financial statements are consolidated.
	Prior to the Share Distribution, transactions between the Company and CTI and CTI’s other subsidiaries were identified in the condensed combined financial statements as transactions between related parties (see Note 3, Expense Allocations and Share Distribution Agreements).
	For the purposes of the condensed combined statements of cash flows, prior to the Share Distribution, the Company reflected changes in unpaid balances with CTI as a financing activity.
	Intercompany accounts and transactions within the Company have been eliminated.
	On April 30, 2013, the Company received a VAT refund approximating $10.9 million, which was recognized as a reduction of service costs in the condensed consolidated statement of operations for the nine months ended October 31, 2013 (see Note 20, Commitments and Contingencies).
	Use of Estimates
	The preparation of the condensed consolidated and combined financial statements and the accompanying notes in conformity with U.S. GAAP requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses.
	The most significant estimates include:
	•	Estimates relating to the recognition of revenue, including the determination of vendor specific objective evidence (“VSOE”) of fair value and the determination of best estimate of selling price for multiple element arrangements;
	•	Allocation of expenses by CTI to the Company;
	•	Fair value of stock-based compensation;
	•	Fair value of reporting units for the purpose of goodwill impairment testing;
	•	Valuation of other intangible assets;
	•	Allowance for doubtful accounts;
	•	Realization of deferred tax assets;
	•	The identification and measurement of uncertain tax positions;
	•	Contingencies and litigation;
	•	Total estimates to complete on percentage-of-completion ("POC") projects;
	•	Valuation of inventory;
	•	Valuation of investments and financial instruments; and
	•	Probability assessment of performance based stock units vesting.
	The Company’s actual results may differ from its estimates.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]	'
Recently Issued Accounting Pronouncements	'
	RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS
	The Company is currently classified as an emerging growth company and as such, can delay adopting new or revised accounting standards until such time as those standards apply to private companies. The Company has elected to follow the required adoption dates for private companies. Therefore, the adoption dates below reflect the Company's current classification.
	Standards Implemented
	In July 2012, the Financial Accounting Standards Board (or FASB) issued new accounting guidance on indefinite-lived intangible assets. The new guidance provides an entity the option first to assess qualitative factors to determine whether the existence of events and circumstances indicates that it is more likely than not that the indefinite-lived intangible asset is impaired. If, after assessing the totality of events and circumstances, an entity concludes that it is not more likely than not that the indefinite-lived intangible asset is impaired, then the entity is not required to take further action. However, if an entity concludes otherwise, then it is required to determine the fair value of the indefinite-lived intangible asset and perform the quantitative impairment test by comparing the fair value with the carrying amount and recognize an impairment loss, if any, to the extent the carrying value exceeds its fair value. The guidance is effective for the Company for annual and, if any, interim impairment tests in the fiscal year ending January 31, 2014. The adoption of this guidance did not have an impact in the interim periods. The Company believes that the adoption of this guidance for the annual impairment test will not have a material impact on its condensed consolidated and combined financial statements.
	Standards To Be Implemented
	In February 2013, the FASB issued new accounting guidance on other comprehensive income. This topic will require the Company to provide information about the amounts reclassified out of accumulated other comprehensive income by component and the line items of net income to which significant amounts are reclassified. The guidance will be effective for the Company beginning February 1, 2014. The adoption of this guidance is anticipated to result in additional disclosures.

Expense Allocations and Share Distribution Agreements [Abstract]	'
Expense Allocations and Share Distribution Agreements	'
	EXPENSE ALLOCATIONS AND SHARE DISTRIBUTION AGREEMENTS
	Expense Allocations
	CTI provided a variety of services to the Company prior to the Share Distribution. CTI directly assigned, where possible, certain general and administrative costs to the Company based on actual use of those services. Where direct assignment of costs was not possible, or practical, CTI used other indirect methods to estimate the allocation of costs. Allocated costs include general support services such as information technology, legal services, human resource services, general accounting and finance, and executive support. Substantially all of these allocations are reflected in “Selling, general, and administrative” expenses in the Company’s condensed combined statements of operations prior to the Share Distribution.
	Employee compensation and overhead expenses were allocated utilizing a time study of CTI employees’ percentage of time spent on Company-related matters. External vendor expenses were allocated based on information provided by the vendor or an internal analysis of benefits derived by the Company from the services incurred by CTI.
	The Company considered these expense allocations to be a reasonable reflection of the utilization of services provided. The allocations may not, however, reflect the expense the Company would have incurred as an independent company. Actual costs which may have been incurred if the Company had been an independent company for the three and nine months ended October 31, 2012 would depend on a number of factors, including how the Company chose to organize itself, and what, if any, functions were outsourced or performed by the Company’s employees. The condensed combined statement of operations includes expense allocation costs from CTI of $0.9 million and $6.0 million for the three and nine months ended October 31, 2012, respectively.
	Share Distribution Agreements
	The Company entered into a distribution agreement (the “Distribution Agreement”), transition services agreement, tax disaffiliation agreement and employee matters agreement (collectively, the “Share Distribution Agreements”) with CTI in connection with the Share Distribution. In particular, the Distribution Agreement, among other things, provides for the allocation between the Company and CTI of various assets, liabilities and obligations attributable to periods prior to the Share Distribution. Under the Distribution Agreement, the Company agreed to indemnify CTI and its affiliates (including Verint following the Verint Merger) against certain losses that may arise as a result of the Verint Merger and the Share Distribution. Certain of the Company's indemnification obligations are capped at $25.0 million and certain are uncapped. Specifically, the capped indemnification obligations include indemnifying CTI and its affiliates (including Verint after the Verint Merger) against losses stemming from breaches by CTI of representations, warranties and covenants in the Verint Merger Agreement and for any liabilities of CTI that were known by CTI but not included on the net worth statement delivered by CTI at the closing of the Verint Merger. The Company's uncapped indemnification obligations include indemnifying CTI and its affiliates (including Verint after the Verint Merger) against liabilities relating to the Company's business; claims by any shareholder or creditor of CTI related to the Share Distribution, the Verint Merger or related transactions or disclosure documents; certain claims made by employees or former employees of CTI and any claims made by employees and former employees of the Company (including but not limited to the Israeli optionholder suits discussed in Note 20, Commitments and Contingencies); any failure by the Company to perform under any of the agreements entered into in connection with the Share Distribution; claims related to CTI's ownership or operation of the Company; claims related to the Starhome Disposition; certain retained liabilities of CTI that are not reflected on or reserved against on the net worth statement delivered by CTI at the closing of the Verint Merger; and claims arising out of the exercise of appraisal rights by a CTI shareholder in connection with the Share Distribution. On February 4, 2013, in connection with the closing of the Verint Merger Agreement, CTI placed $25.0 million in escrow to support indemnification claims to the extent made against the Company by Verint and any cash balance remaining in such escrow fund 18 months after the closing of the Verint Merger, less any claims made on or prior to such date, will be released to the Company. The escrow funds cannot be used for claims related to the Israeli optionholder suits. The Company also assumed all pre-Share Distribution tax obligations of each of the Company and CTI.
	The Company and CTI entered into a tax disaffiliation agreement that governs their respective rights, responsibilities and obligations after the Share Distribution with respect to tax liabilities and benefits, tax attributes, tax contests and other tax matters regarding income taxes, other taxes and related tax returns. The Company and CTI also entered into an employee matters agreement, which allocates liabilities and responsibilities relating to employee compensation and benefit plans and programs.

	(1) The amount of goodwill in “Comverse Other” is attributable to Comverse MI and Netcentrex. The goodwill associated with Netcentrex was impaired during the fiscal year ended January 31, 2009 and prior fiscal years. The goodwill associated with Comverse MI was impaired during the fiscal year ended January 31, 2013.
	The Company tests goodwill for impairment annually as of November 1 or more frequently if events or circumstances indicate the potential for impairment exists. During the three months ended October 31, 2012, the Comverse MI reporting unit experienced intensified competition, price erosion, and significant decline in capacity upgrades from existing customers, necessitating an interim impairment test as of October 31, 2012. As a result of the interim impairment test, the Company determined that goodwill for the Comverse MI reporting unit was impaired and recorded an impairment expense of approximately $5.6 million during the three months ended October 31, 2012.
	Using the adjusted net asset value method to determine the fair value of its Comverse MI reporting unit, the Company estimated the amount a market participant would be willing to pay for each of the individual assets of the Comverse MI reporting unit, net of liabilities. The Company's estimate was based on a number of subjective factors, including: (i) the realizable value resulting from the sale of accounts receivables and inventory, (ii) the magnitude and timing of future revenue streams associated with Comverse MI's technology and trademarks, and (iii) discount rate of forecasted cash flows.
	No events or circumstances indicating the potential for goodwill impairment were identified during the nine months ended October 31, 2013.

	RESTRUCTURING
	The Company reviews its business, manages costs and aligns resources with market demand. As a result, the Company has taken several actions to improve its cash position, reduce fixed costs, eliminate redundancies, strengthen operational focus and better position itself to respond to market pressures or unfavorable economic conditions.
	Fourth Quarter 2012 Initiatives
	During the fourth quarter of the fiscal year ended January 31, 2013, following the Share Distribution, the Company commenced certain initiatives to restructure its operations and reorganize its activities and go-to-market strategy, including a plan to restructure the operations of the Company with a view towards aligning operating costs and expenses with anticipated revenue and the new go-to-market strategy. In relation to this restructuring plan, the Company recorded severance-related costs of $3.2 million and facilities-related costs of $4.8 million for the nine months ended October 31, 2013. Severance-related costs and facilities-related costs of $5.4 million and $1.1 million, respectively, were paid during the nine months ended October 31, 2013. The remaining severance and facilities-related costs accrued under the plan are expected to be paid by January 2014 and October 2019, respectively.
	Third Quarter 2010 Restructuring Initiatives and Business Transformation
	During the second half of the fiscal year ended January 31, 2011, the Company commenced certain initiatives to improve its cash position, including a plan to restructure its operations with a view towards aligning operating costs and expenses with anticipated revenue. The Company implemented the first phase of such plan commencing in the third quarter of the fiscal year ended January 31, 2011, reducing its annualized operating costs. During the fiscal year ended January 31, 2012, the Company implemented a second phase of measures (the “Phase II Business Transformation”) that focused on process reengineering to maximize business performance, productivity and operational efficiency. As part of the Phase II Business Transformation, the Company restructured its operations into new business units that are designed to improve operational efficiency and business performance. One of the primary purposes of the Phase II Business Transformation is to solidify the Company’s leadership in BSS and leverage the growth in mobile data usage, while maintaining its leading market position in VAS and implementing further cost savings through operational efficiencies and strategic focus. The remaining facilities-related costs accrued under the plan are expected to be paid by May 2017.
	Netcentrex 2010 Initiative
	During the fiscal year ended January 31, 2011, management, as part of initiatives to improve focus on the Company’s core business and to maintain its ability to face intense competitive pressures in its markets, approved the first phase of a restructuring plan to eliminate staff positions primarily located in France.

	The Company entered into derivative arrangements to manage a variety of risk exposures during the nine months ended October 31, 2013 and 2012, including foreign currency risk related to forecasted foreign currency denominated payroll costs. The Company assessed the counterparty credit risk for each party related to its derivative financial instruments for the periods presented.
	Forward Contracts
	During the nine months ended October 31, 2013 and 2012, the Company entered into a series of short-term foreign currency forward contracts to limit the variability in exchange rates between the U.S. dollar and the new Israeli shekel (“NIS”) to hedge probable cash flow exposure from expected future payroll expense. The transactions qualified for cash flow hedge accounting under the FASB’s guidance and there was no hedge ineffectiveness. Accordingly, the Company recorded all changes in fair value of the forward contracts as part of other comprehensive income (loss) in the condensed consolidated and combined statements of comprehensive income (loss). Such amounts are reclassified to the statements of operations when the effects of the item being hedged are recognized. The Company’s derivatives outstanding as of October 31, 2013 and January 31, 2013 are short-term in nature and are due to contractually settle within the next twelve months.

Fair Value Disclosures [Abstract]	'
Fair Value Measurements	'
	FAIR VALUE MEASUREMENTS
	Under the FASB’s guidance, fair value is defined as the price that would be received in the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (i.e., “the exit price”).
	The FASB’s guidance also establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value. The fair value hierarchy consists of three levels based on the reliability of inputs as follows:
	•	Level 1 – Valuations based on quoted prices in active markets for identical instruments that the Company is able to access. Since valuations are based on quoted prices that are readily and regularly available in an active market, valuation of these instruments does not entail a significant degree of judgment.
	•	Level 2 – Valuations based on quoted prices in active markets for instruments that are similar, or quoted prices in markets that are not active for identical or similar instruments, and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets.
	•	Level 3 – Valuations based on inputs that are unobservable and significant to the overall fair value measurement.
	Assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurements. Changes in the observability of valuation inputs may result in transfers within fair value measurement hierarchy. All transfers into and/or out of all levels are assumed to occur at the end of the reporting period. The Company did not have any transfers between levels of the fair value measurement hierarchy during the nine months ended October 31, 2013 and 2012.
	Assets and Liabilities Measured at Fair Value on a Recurring Basis
	The fair value of financial instruments is estimated by the Company, using available market information and appropriate valuation methodologies. However, considerable judgment is required in interpreting market data to develop the estimates of fair value. Accordingly, the estimates presented herein are not necessarily indicative of the amounts that the Company could realize in a market exchange. The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts.
	Commercial paper. The Company uses quoted prices for similar assets and liabilities.
	Money Market Funds. The Company values these assets using quoted market prices for such funds.
	Derivative assets. The fair value of derivative instruments is based on quotes or data received from counterparties and third party financial institutions. These quotes are reviewed for reasonableness by discounting the future estimated cash flows under the contracts, considering the terms and maturities of the contracts and market rates for similar contracts using readily observable market prices thereof.
	The following tables present financial instruments according to the fair value hierarchy as defined by the FASB’s guidance:

As of January 31, 2013, $9.4 million of commercial paper and $38.5 million of money market funds were classified in “Cash and cash equivalents” within the consolidated balance sheet.
	Assets and Liabilities Not Measured at Fair Value on a Recurring Basis
	In addition to assets and liabilities that are measured at fair value on a recurring basis, the Company also measures certain assets and liabilities at fair value on a nonrecurring basis. The Company measures non-financial assets, classified within Level 3 of the fair value hierarchy, including goodwill, intangible assets and property, plant and equipment, at fair value when there is an indication of impairment. These assets are recorded at fair value only when an impairment expense is recognized. The Company has elected not to apply the fair value option for non-financial assets and non-financial liabilities.
	The carrying amounts of cash and cash equivalents, restricted cash and bank time deposits, accounts receivable and accounts payable are reasonable estimates of their fair value.
	During the three months ended October 31, 2012, the Company recorded an impairment expense of approximately $5.6 million (see Note 5, Goodwill).

The Company’s liability for severance pay is calculated pursuant to Israel’s Severance Pay Law based on the most recent monthly salary of the employee multiplied by the number of years of employment, as of the balance sheet date. Employees are entitled to one month’s salary for each year of employment or a portion thereof. A portion of such liability is funded by monthly deposits into insurance policies, which are restricted to only be used to satisfy such severance payments. The amount of deposits is classified in “Other assets” within the condensed consolidated balance sheets as severance pay fund in the amounts of $36.0 million and $36.3 million as of October 31, 2013 and January 31, 2013, respectively.

	STOCK-BASED COMPENSATION
	Comverse, Inc. 2012 Stock Incentive Compensation Plan
	In October 2012, in connection with the Share Distribution the Company adopted the Comverse, Inc. 2012 Stock Incentive Compensation Plan (the "2012 Incentive Plan"). The 2012 Incentive Plan provides for the issuance of nonqualified stock options, incentive stock options, stock appreciation rights, restricted stock, other stock-based awards and performance-based compensation awards (collectively, the "Awards") based on shares of Comverse common stock ("Shares"). The Company's employees, non-employee directors and consultants as well as employees and consultants of its subsidiaries and affiliates are eligible to receive Awards.
	A total of 2.5 million Shares are reserved for issuance under future Awards to be granted under the 2012 Incentive Plan following the effective date of the 2012 Incentive Plan (referred to as the "Future Awards"). As of October 31, 2013, Future Awards of approximately 0.7 million Shares have been granted.
	Replacement of CTI's Equity-Based Compensation Awards
	Pursuant to the terms of the Share Distribution, certain awards that were previously granted under CTI's stock incentive plan to the Company's employees and consultants have been replaced by awards that relate to the Company's common stock and have been assumed by the 2012 Incentive Plan (the "Assumed CTI Awards"). A total of 5.0 million Shares were reserved for issuance under the Assumed CTI Awards. Such reserved Shares may only be issued pursuant to the Assumed CTI Awards and may not be issued pursuant to any Future Awards. In connection with the Share Distribution, the Company issued 857,280 restricted stock units and 495,894 options to purchase shares of the Company's common stock to replace CTI Awards previously granted to the Company's employees. The replacement of CTI's equity-based compensation awards was considered a modification of an award. As a result, the Company compared the fair value of the awards immediately prior to the Share Distribution to the fair value of the awards immediately after the Share Distribution to measure incremental compensation cost. The modification resulted in an increase in the fair value of the awards. The amount of non-cash compensation expense was negligible.
	Share-Based Awards
	Certain employees of the Company have historically received, under stock incentive compensation plans maintained by CTI, share-based awards, including stock options, deferred stock unit and restricted stock unit awards, entitling the recipients to acquire or receive shares of CTI common stock. Accordingly, the following presentation reflects the stock-based compensation expense attributable to awards granted by CTI to employees of the Company for the three and nine months ended October 31, 2012. Amounts presented may not be indicative of future stock-based compensation expense and may not necessarily reflect the stock-based compensation expense that the Company would have recorded had it been an independent, publicly-traded company for the periods presented.
	Stock-based compensation expense associated with awards made by the Company for the three and nine months ended October 31, 2013 and by CTI for employees of the Company for the three and nine months ended October 31, 2012, is included in the Company’s condensed consolidated and combined statements of operations as follows:
		Three Months Ended October 31,				Nine Months Ended October 31,

	Stock-based compensation expense associated with options granted by Starhome to Starhome’s employees is included in discontinued operations and therefore not presented in the table above. For the three and nine months ended October 31, 2012, such stock-based compensation expense was $0.3 million and $0.5 million, respectively.
	Restricted Awards and Stock Options
	The Company grants restricted stock unit awards subject to vesting provisions (collectively, “Restricted Awards”) and stock options to certain key employees and directors. For the three and nine months ended October 31, 2013, the Company granted Restricted Awards covering an aggregate of 4,014 and 312,009 Shares, respectively, of which 116,279 were performance based awards granted in the nine months ended October 31, 2013. For the three and nine months ended October 31, 2013, the Company granted stock options to purchase an aggregate of 17,424 and 342,157 Shares, respectively.
	During the three and nine months ended October 31, 2013, 10,551 and 31,501 Shares, respectively, were issued upon exercise of stock options under the 2012 Incentive Plan. Total proceeds from these Shares were $0.3 million and $0.8 million, respectively.
	During the three and nine months ended October 31, 2012, CTI granted Restricted Awards covering an aggregate of 64,893 and 3,251,589 shares, respectively, of CTI’s common stock to certain executive officers and key employees of the Company.
	During the three and nine months ended October 31, 2012, CTI granted stock options to purchase an aggregate of 296,356 and 1,385,000 shares, respectively, of CTI's common stock to certain executive officers of the Company.
	During the three and nine months ended October 31, 2012, 4,562 and 9,064 shares, respectively, of CTI common stock were issued to certain employees of the Company upon exercise of stock options under CTI’s stock incentive plans. Total proceeds for these shares were negligible.
	As of October 31, 2013, stock options to purchase 796,615 Shares and Restricted Awards covering 714,112 Shares were outstanding and 1,794,392 Shares were available for future grant under the 2012 Incentive Plan.
	The fair market value of the Company's Restricted Awards that vested during the three and nine months ended October 31, 2013 was $0.2 million and $8.2 million, respectively.
	The total fair market value of CTI's Restricted Awards pertaining to the Company's employees that vested during the three and nine months ended October 31, 2012, was $0.1 million and $3.8 million, respectively.
	As of October 31, 2013, the unrecognized Company compensation expense, net of estimated forfeitures, related to unvested Restricted Awards was $14.1 million, which is expected to be recognized over a weighted-average period of 1.73 years.
	The Company's outstanding stock options as of October 31, 2013 include unvested stock options to purchase 581,609 Shares with a weighted-average grant date fair value of $9.01, an expected term of 4.0 years and a total fair value of $5.2 million. The unrecognized compensation expenses related to the remaining unvested stock options to purchase Shares was $4.2 million, which is expected to be recognized over a weighted-average period of 1.99 years.
	The fair value of stock options to purchase Shares that vested during the three and nine months ended October 31, 2013 was $0.2 million and $0.9 million, respectively, and the fair value of stock options to purchase CTI's common stock pertaining to the Company's employees that vested during the nine months ended October 31, 2012 was $0.3 million.

	DISCONTINUED OPERATIONS
	Starhome was a CTI Subsidiary (66.5% owned as of January 31, 2012). On August 1, 2012, CTI, certain other Starhome shareholders and Starhome entered into a Share Purchase Agreement (the “Starhome Share Purchase Agreement”) with Fortissimo Capital Fund II (Israel), L.P., Fortissimo Capital Fund III (Israel), L.P. and Fortissimo Capital Fund III (Cayman), L.P. (collectively, “Fortissimo”) pursuant to which Fortissimo agreed to purchase all of the outstanding share capital of Starhome (the “Starhome Disposition”). On September 19, 2012, CTI, in order to ensure it could meet the conditions of the Verint Merger, contributed to the Company its interest in Starhome, including its rights and obligations under the Starhome Share Purchase Agreement discussed below. The Starhome Disposition was completed on October 19, 2012.
	Under the terms of the Starhome Share Purchase Agreement, Starhome’s shareholders received aggregate cash proceeds of approximately $81.3 million, subject to adjustment for fees, transaction expenses and certain taxes. Of this amount, $10.5 million is held in escrow to cover potential post-closing indemnification claims, with $5.5 million being released after 18 months and the remainder released after 24 months, in each case, less any claims made on or prior to such dates. The Company received aggregate net cash consideration (including $4.9 million deposited in escrow at closing) of approximately $37.2 million, after payments that CTI agreed to make to certain other Starhome shareholders of up to $4.5 million. The escrow funds are available to satisfy certain indemnification claims under the Starhome Share Purchase Agreement to the extent that such claims exceed $1.0 million. As of October 31, 2013 such claims have not exceeded the $1.0 million threshold.
	The Company and Starhome shareholders have made customary representations and warranties and covenants in the Starhome Share Purchase Agreement, including an agreement not to solicit Starhome employees or interfere with Starhome’s clients, customers, suppliers, licensor's or other business relationships for a period of four years following the closing. The Company has also agreed for a period of four years following the closing (October 19, 2012) that it will not, and will cause its affiliates not to, create, design, develop or offer for sale any product or service which directly competes with any products or services offered by Starhome, subject to certain limited exceptions. In addition, as contemplated by the Starhome Share Purchase Agreement, Starhome and the Company entered into a transition services agreement at the closing of the Starhome Disposition.
	The Company does not have significant continuing involvement in Starhome's operations following the closing of the
	Starhome Disposition, and accordingly, the results of operations of Starhome are included in discontinued operations, less applicable income taxes, as a separate component of net loss in the Company's combined statements of operations for the three and nine months ended October 31, 2012.
	Starhome's results of operations included in discontinued operations were as follows:

	The Company and Starhome had previously entered into transactions pursuant to which the Company performed certain production, support and maintenance services for Starhome, and these transactions continue following the completion of the Starhome Disposition. The Company does not consider these transactions to be significant. The Company recognized revenue related to transactions with Starhome of $0.1 million and $1.2 million for the three and nine months ended October 31, 2013, respectively. The Company had a net receivable balance of $0.1 million and $1.6 million as of October 31, 2013 and January 31, 2013, respectively.

	During the three and nine months ended October 31, 2013, the diluted earnings per share attributable to Comverse, Inc. computation excludes 0.7 million shares of stock-based awards from the calculations because their inclusion would have been anti-dilutive. Antidilutive securities include outstanding stock options with exercise prices and average unrecognized compensation cost in excess of the average fair market value of common stock for the related period.
	The computation of basic and diluted earnings (loss) per share for the three and nine months ended October 31, 2012 is calculated using the number of shares of the Company's common stock outstanding on October 31, 2012, following the Share Distribution.
	For the three and nine months ended October 31, 2012, there were no dilutive shares as there were no actual shares or share-based awards outstanding for Comverse, Inc. prior to the Share Distribution.

Income Tax Disclosure [Abstract]	'
Income Taxes	'
	INCOME TAXES
	The Company's quarterly provision for income taxes is measured using an annual effective tax rate, adjusted for discrete items that occur within the periods presented. The significant differences that impact the effective tax rate relate to the difference between the U.S. federal statutory rate and the rates in foreign tax jurisdictions, incremental valuation allowances and tax contingencies.
	The Company recorded an income tax benefit from continuing operations of $11.3 million for the three months ended October 31, 2013, representing an effective tax rate of (95.8)% compared with an income tax expense from continuing operations of $11.8 million, representing an effective tax rate of 982.0% for the three months ended October 31, 2012. During the three months ended October 31, 2013 and 2012, the effective tax rates were different from the U.S. statutory rate primarily due to the fact that the Company did not record an income tax benefit on losses incurred in certain of the Company's U.S. and foreign tax jurisdictions in which the Company maintain valuation allowances against the Company's net deferred tax assets. The income tax provisions from continuing operations are comprised of income tax expense recorded in non-loss tax jurisdictions, withholding taxes and certain tax contingencies. The change in the Company's effective tax rate for the three months ended October 31, 2013, compared to the three months ended October 31, 2012 was primarily attributable to changes in the relative mix of income and losses across various tax jurisdictions, and the fact that the Company has to compute a separate effective tax rate for certain tax jurisdictions incurring losses.
	For the nine months ended October 31, 2013 and 2012, the Company recorded an income tax expense from continuing operations of $23.5 million and $19.1 million, respectively, which represents an effective tax rate of 89.0% and (159.5)% respectively. The effective tax rate for the nine months ended October 31, 2012 was negative due to the fact that the Company recorded income tax expense on a consolidated and combined pre-tax loss primarily due to the mix of income and losses by tax jurisdiction. The Company did not record an income tax benefit on the jurisdictional losses for the period, primarily because it maintains valuation allowances against certain of its U.S. and foreign net deferred tax assets. The income tax provisions from continuing operations for the periods are comprised of income tax expense recorded in non-loss tax jurisdictions, withholding taxes, and certain tax contingencies.
	As required by the authoritative guidance on accounting for income taxes, the Company evaluates the realizability of deferred tax assets on a tax jurisdictional basis at each reporting date. Accounting for income taxes requires that a valuation allowance be established when it is more-likely-than-not that all or a portion of the deferred tax assets will not be realized. In circumstances where there is sufficient negative evidence indicating that the deferred tax assets are not more-likely-than-not realizable, the Company establishes a valuation allowance. The Company determined that there is sufficient negative evidence to maintain valuation allowances against certain of the Company's federal, state and foreign deferred tax assets as a result of historical losses in the most recent three-year period in the U.S. and certain state and foreign tax jurisdictions. During the nine months ended October 31, 2013, the Company reassessed its valuation allowance requirements taking into consideration the Share Distribution and concluded that it intends to maintain its valuation allowance until sufficient positive evidence exists to support its reversal.
	The Company regularly assesses the adequacy of the Company's provisions for income tax contingencies in accordance with the applicable authoritative guidance on accounting for income taxes. As a result, the Company may adjust the reserves for unrecognized tax benefits for the impact of new facts and developments, such as changes to interpretations of relevant tax law, assessments from taxing authorities, settlements with taxing authorities, and lapses of statutes of limitation. As of October 31, 2013, the total amount of unrecognized tax benefits that, if recognized, would impact the Company's effective tax rate were approximately $107.3 million (see Note 12, Other Long-Term Liabilities). The Company believes that it is reasonably possible that the total amount of unrecognized tax benefits as of October 31, 2013 could decrease by approximately $1.8 million in the next twelve months as a result of settlements of certain tax audits or lapses of statutes of limitation. Such decreases may involve the payment of additional taxes, the adjustment of deferred taxes, including the need for additional valuation allowances and the recognition of tax benefits. The Company's income tax returns are subject to ongoing tax examinations in several tax jurisdictions in which the Company operates. The Company believes that it is reasonably possible that new issues may be raised by tax authorities or developments in tax audits may occur which would require increases or decreases to the balance of reserves for unrecognized tax benefits. However, an estimate of such changes cannot reasonably be made.
	The Company's policy is to include interest and penalties related to unrecognized tax benefits as a component of the provision for income taxes in the condensed consolidated and combined statements of operations. Accrued interest and penalties was $51.2 million as of October 31, 2013.

	NESS SEGMENT INFORMATION
	The Company’s reportable segments consist of Comverse BSS and Comverse VAS. The results of operations of all the other operations of the Company, including Comverse MI, the Company’s Netcentrex operations, the Company’s global corporate functions that support its business units and Exalink, are included in the column captioned “Comverse Other” as part of the Company’s business segment presentation. The operating segments included in “Comverse Other” do not meet the quantitative thresholds required for a separate presentation or the aggregation criteria under segment reporting guidance. Specifically, they do not have similar economic characteristics with any separately presented reportable segment. The Company does not maintain balance sheets for its operating segments.
	Starhome's results of operations are included as discontinued operations and therefore are not presented in segment information.
	Segment Performance
	The Company evaluates its business by assessing the performance of each of its operating segments. The Company’s Chief Executive Officer is its chief operating decision maker (“CODM”). The CODM uses segment performance, as defined below, as the primary basis for assessing the financial results of the operating segments and for the allocation of resources. Segment performance, as the Company defines it in accordance with the FASB’s guidance relating to segment reporting, is not necessarily comparable to other similarly titled captions of other companies.
	Segment performance is computed by management as income (loss) from operations adjusted for the following: (i) stock-based compensation expense; (ii) amortization of acquisition-related intangibles; (iii) compliance-related professional fees; (iv) compliance-related compensation and other expenses; (v) impairment of goodwill; (vi) impairment of property and equipment; (vii) certain litigation settlements and related costs; (viii) Italian VAT refund recovery recorded within operating expenses; (ix) restructuring expenses; and (x) certain other gains and expenses. Compliance-related professional fees and compliance-related compensation and other expenses relate to fees and expenses recorded in connection with CTI’s and our efforts to (a) complete certain financial statements and audits of such financial statements and (b) remediate material weaknesses in internal control over financial reporting.
	The tables below present information about total revenue, total costs and expenses, income (loss) from operations, segment performance, interest expense, and depreciation and amortization for the three and nine months ended October 31, 2013 and 2012:

	COMMITMENTS AND CONTINGENCIES
	Guarantees
	The Company provides certain customers in the ordinary course of business with financial performance guarantees, which in certain cases are backed by standby letters of credit or surety bonds, the majority of which are cash collateralized and accounted for as restricted cash and bank time deposits. The Company is only liable for the amounts of those guarantees in the event of its nonperformance, which would permit the customer to exercise the guarantee. As of October 31, 2013 and January 31, 2013, the Company believes that it was in compliance with its performance obligations under all contracts for which there is a financial performance guarantee, and that any liabilities arising in connection with these guarantees will not have a material adverse effect on the Company’s condensed consolidated results of operations, financial position or cash flows. The Company also obtained bank guarantees primarily to provide customer assurance relating to the performance of certain obligations required by customer agreements for the guarantee of certain payment obligations. These guarantees, which aggregated $31.1 million as of each of October 31, 2013 and January 31, 2013, respectively, are generally scheduled to be released upon the Company’s performance of specified contract milestones, a majority of which are scheduled to be completed at various dates through May 31, 2016.
	Litigation Overview
	Except as disclosed below, the Company does not believe that it is currently party to any other claims, assessments or pending legal action that could reasonably be expected to have a material adverse effect on its business, financial condition or results of operations.
	Israeli Optionholder Class Actions
	CTI and certain of its former subsidiaries, including Comverse Ltd. (a subsidiary of the Company), were named as defendants in four potential class action litigations in the State of Israel involving claims to recover damages incurred as a result of purported negligence or breach of contract due to previously-settled allegations regarding illegal backdating of CTI options that allegedly prevented certain current or former employees from exercising certain stock options. The Company intends to vigorously defend these actions.
	Two cases were filed in the Tel Aviv District Court against CTI on March 26, 2009, by plaintiffs Katriel (a former Comverse Ltd. employee) and Deutsch (a former Verint Systems Ltd. employee). The Katriel case (Case Number 1334/09) and the Deutsch case (Case Number 1335/09) both seek to approve class actions to recover damages that are claimed to have been incurred as a result of CTI's negligence in reporting and filing its financial statements, which allegedly prevented the exercise of certain stock options by certain employees and former employees. By stipulation of the parties, on September 30, 2009, the court ordered that these cases, including all claims against CTI in Israel and the motion to approve the class action, be stayed until resolution of the actions pending in the United States regarding stock option accounting, without prejudice to the parties' ability to investigate and assert the unique facts, claims and defenses in these cases. On May 7, 2012, the court lifted the stay, and the plaintiffs have filed an amended complaint and motion to certify a class of plaintiffs in a single consolidated class action. The defendants responded to this amended complaint on November 11, 2012, and the plaintiffs filed a further reply on December 20, 2012. A pre-trial hearing for the case was held on December 25, 2012, during which all parties agreed to attempt to settle the dispute through mediation. The mediation process is currently ongoing.
	Separately, on July 13, 2012, plaintiffs filed a motion seeking an order that CTI hold back $150 million in assets as a reserve to satisfy any potential damage awards that may be awarded in this case, but did not seek to enjoin the Share Distribution. The Company does not believe that the motion has merit. On July 25, 2012, the court indicated that it will not rule on the motion until after it rules on plaintiffs' motion to certify a class of plaintiffs. On August 16, 2012, plaintiffs filed a motion for leave to appeal the court's order to the Israeli Supreme Court and on November 11, 2012, CTI responded to plaintiff's motion. The parties are awaiting a decision.
	Two cases were also filed in the Tel Aviv Labor Court by plaintiffs Katriel and Deutsch, and both sought to approve class actions to recover damages that are claimed to have been incurred as a result of breached employment contracts, which allegedly prevented the exercise by certain employees and former employees of certain CTI and Verint stock options, respectively. The Katriel litigation (Case Number 3444/09) was filed on March 16, 2009, against Comverse Ltd., and the Deutsch litigation (Case Number 4186/09) was filed on March 26, 2009, against Verint Systems Ltd. The Tel Aviv Labor Court has ruled that it lacks jurisdiction, and both cases have been transferred to the Tel Aviv District Court. These cases have been consolidated with the Tel Aviv District Court cases discussed above. The Company did not accrue for these matters as the potential loss is currently not probable or estimable.
	Additionally, two cases have been filed by individual plaintiffs similarly seeking to recover damages up to an aggregate of $3.6 million allegedly incurred as a result of the inability to exercise certain stock options. The cases generally allege the same causes of actions alleged in the potential class action discussed above. As of October 31, 2013, the Company accrued $0.2 million for one of these cases (the “Accrued Case”) but did not accrue for the other matter as the potential loss is currently not probable or estimable. In December 2013, the Accrued Case was settled in accordance with the accrual.
	France Labor Contingency
	A former employee based in France has filed a notice of appeal in the appellate court, seeking to overturn a decision of the Labor Court rejecting his claim to requalify his resignation as a constructive dismissal and for damages in the Labor Court of approximately $2.8 million. The Company is disputing this appeal and intends to vigorously defend it. The Company has not accrued for this matter as the potential loss is not currently probable.
	Other Legal Proceedings
	From time to time, we and our subsidiaries are subject to claims in legal proceedings arising in the normal course of business. We do not believe that we or our subsidiaries are currently party to any pending legal action not described herein or disclosed in our consolidated and combined financial statements that could reasonably be expected to have a material adverse effect on our business, financial condition or results of operations.
	Indemnifications
	In the normal course of business, the Company provides indemnifications of varying scopes to customers against claims of intellectual property infringement made by third parties arising from the use of the Company's products. The Company evaluates its indemnifications for potential losses and in its evaluation considers such factors as the degree of probability of an unfavorable outcome and the ability to make a reasonable estimate of the amount of loss. Generally, the Company has not encountered significant expenses as a result of such indemnification provisions.
	To the extent permitted under state laws or other applicable laws, the Company has agreements in which it agreed to indemnify its directors and officers for certain events or occurrences while the director or officer is, or was, serving at the Company's request in such capacity. The indemnification period covers all pertinent events and occurrences during the Company's director's or officer's lifetime. The maximum potential amount of future payments that the Company could be required to make under these indemnification agreements is unlimited; however, the Company has certain director and officer insurance coverage that limits the Company's exposure and enables the Company to recover a portion of any future amounts paid. The Company is not able to estimate the fair value of these indemnification agreements in excess of applicable insurance coverage, if any.
	In addition, under the Share Distribution Agreements the Company entered into in connection with the Share Distribution, the Company has agreed to indemnify CTI and its affiliates (including Verint following the Verint Merger) against certain losses that may arise as a result of the Verint Merger and the Share Distribution (see Note 3, Expense Allocations and Share Distribution Agreements). On February 4, 2013, in connection with the closing of the Verint Merger Agreement, CTI placed $25.0 million in escrow to support indemnification claims to the extent made against the Company by Verint and any cash balance remaining in such escrow fund 18 months after the closing of the Verint Merger, less any claims made on or prior to such date, will be released to the Company.
	Brazil Tax and Labor Contingencies
	The Company's operations in Brazil are involved in various litigation matters and have received or been the subject of numerous governmental assessments related to indirect and other taxes, as well as disputes associated with former Company employees. The tax matters, which comprise a significant portion of the contingencies, principally relate to claims for taxes on the transfers of inventory, municipal service taxes on rentals and gross revenue taxes. The Company is disputing these tax matters and intends to vigorously defend its positions. The labor matters principally relate to claims made by former Company employees for pay wages, social security and other related labor benefits, as well as related tax obligations. As of October 31, 2013, the total amounts related to the reserved portion of the tax and labor contingencies was $0.1 million and the unreserved portion of the tax and labor contingencies totaled approximately $9.3 million. With respect to the unreserved balance, these have been assessed by management as being either remote or possible as to the likelihood of ultimately resulting in a loss to the Company. Local laws and regulations often require that the Company make deposits or post other security in connection with such proceedings. As of October 31, 2013, the Company had $7.3 million of deposits with the government in Brazil for claims that the Company is disputing which provides security with respect to these matters. Generally, any deposits would be refundable to the extent the matters are resolved in the Company's favor. Management routinely assesses these matters as to probability of ultimately incurring a liability against the Company's Brazilian operations and the Company records its best estimate of the ultimate loss in situations where management assesses the likelihood of an ultimate loss as probable.
	Italy VAT
	The Company applied for Italian VAT refunds for the periods 2004 to 2010. However, collectability was deemed uncertain, as a result of the Italian financial crisis and other matters. On April 30, 2013, the Company received a refund approximating $10.9 million, which was recognized as a reduction of service costs in the condensed consolidated statement of operations for the nine months ended October 31, 2013.
