Revenue Recognition and Deferred Revenue [Abstract]
Revenue Recognition	Note 2—Revenue Recognition The Company earns revenue from contracts with customers, primarily through the provision of retail telecommunications and payment offerings as well as wholesale international long-distance traffic termination. The Company has two reportable business segments, Telecom & Payment Services and net2phone. The Telecom & Payment Services segment is comprised of Core and Growth verticals. Core includes BOSS Revolution Calling, an international long-distance calling service marketed primarily to immigrant communities in the United States, Carrier Services, which provides international long-distance termination and outsourced traffic management solutions to telecoms worldwide, and Mobile Top-Up, which enables customers to transfer airtime and bundles of airtime, messaging and data credits to mobile accounts internationally and domestically. Core also includes smaller communications and payment offerings, many in harvest mode. Growth includes National Retail Solutions, which operates a point-of-sale terminal-based network for independent retailers, BOSS Revolution Money Transfer, an international money remittance service for customers in the United States, and BOSS Revolution Mobile, a mobile virtual network operator in the United States. The net2phone segment is comprised of net2phone-Unified Communications as a Service ("UCaaS"), a unified cloud-based communications service for businesses in North and South America and certain other international markets, and net2phone-Platform Services, which provides telephony services to cable operators and other businesses by leveraging a common technology platform. The Company's core operations are mostly minute-based, paid-voice communications services, and revenue is primarily recognized at a point in time. The Company's Telecom & Payment Services' growth initiatives and net2phone-UCaaS are technology-driven, synergistic businesses that leverage the Company's core assets, and revenue, in some cases, is recognized over time. The Company's most significant revenue streams are from BOSS Revolution Calling, Mobile Top-Up, and Carrier Services. BOSS Revolution Calling and Mobile Top-Up are sold direct-to-consumers and through distributors and retailers.

The Company does not have any significant revenue from performance obligations satisfied or partially satisfied in previous reporting periods. The Company's remaining performance obligations at January 31, 2020 had an original expected duration of one year or less. Accounts Receivable and Contract Balances The timing of revenue recognition may differ from the time of billing to the Company's customers. Trade accounts receivable in the Company's consolidated balance sheets represent unconditional rights to consideration. An entity records a contract asset when revenue is recognized in advance of the entity's right to bill and receive consideration. The Company has not identified any contract assets. Contract liabilities arise when the Company receives consideration or bills its customers prior to providing the goods or services promised in the contract. The primary component of the Company's contract liability balance is the payments received for its prepaid BOSS Revolution Calling, traditional calling cards, and Mobile Top-Up services. Contract liabilities are recognized as revenue when services are provided to the customer. The contract liability balances are presented in the Company's consolidated balance sheet as "Deferred revenue". The following table presents information about the Company's contract liability balance: Three Months Ended Six Months Ended 2020 2019 2020 2019 (in thousands) Revenue recognized in the period from amounts included in the contract liability balance at the beginning of the period $ 28,586 $ 28,502 $ 34,234 $ 36,177 Deferred Customer Contract Acquisition and Fulfillment Costs The Company recognizes as an asset its incremental costs of obtaining a contract with a customer that it expects to recover. The Company charges its direct costs to fulfill contracts to expense as incurred. The Company's incremental costs of obtaining a contract with a customer are sales commissions paid to acquire customers. For Telecom & Payment Services, the Company applies the practical expedient whereby the Company primarily charges these costs to expense when incurred because the amortization period would be one year or less for the asset that would have been recognized from deferring these costs. For net2phone-UCaaS sales, employees and third parties receive commissions on sales to end users. The Company amortizes the deferred costs over the expected customer relationship period when it is expected to exceed one year. The Company's deferred customer contract acquisition costs were as follows: January 31, July 31, (in thousands) Deferred customer contract acquisition costs included in "Other current assets" $ 1,992 $ 1,474 Deferred customer contract acquisition costs included in "Other assets" 2,069 1,716 Total $ 4,061 $ 3,190 The Company's amortization of deferred customer contract acquisition costs during the periods were as follows: Three Months Ended Six Months Ended 2020 2019 2020 2019 (in thousands) Amortization of deferred customer contract acquisition costs $ 615 $ 557 $ 1,166 $ 752

Leases

Leases [Abstract]
Leases	Note 3—Leases On August 1, 2019, the Company adopted Accounting Standards Update No. 2016-02, Leases (Topic 842) The Company elected to apply the optional ASC 842 transition provisions beginning on August 1, 2019. Accordingly, the Company will continue to apply Topic 840 prior to August 1, 2019, including Topic 840 disclosure requirements, in the comparative periods presented. The Company elected the package of practical expedients for all its leases that commenced before August 1, 2019. In addition, the Company elected not to apply the recognition requirements of ASC 842 for its short-term leases. The Company's leases primarily consist of operating leases for office space. These leases have remaining terms from one to six years. net2phone-UCaaS also has operating leases for office equipment. Certain of these leases include renewal options that may be exercised and/or options to terminate the lease. The Company has concluded that it is not reasonably certain that it would exercise the options to extend the lease or terminate the lease. The adoption of ASC 842 resulted in the recognition of operating lease liabilities of $12.4 million and operating ROU assets of the same amount as of August 1, 2019 based on the present value of the remaining minimum rental payments associated with the Company's leases. As the Company's leases do not provide an implicit rate, nor is one readily available, the Company used its incremental borrowing rate based on information available at August 1, 2019 to determine the present value of its future minimum rental payments. net2phone has equipment leases that were classified as capital leases under Topic 840 and are finance leases under ASC 842. net2phone is also the lessor in various equipment leases that were classified as sales-type capital leases under Topic 840, that are classified as sales-type finance leases under ASC 842. The assets and liabilities related to these finance leases are not material to the Company's consolidated balance sheets. On March 26, 2018, the Company completed a pro rata distribution of the common stock that the Company held in the Company's former subsidiary, Rafael Holdings, Inc. ("Rafael") to the Company's stockholders of record as of the close of business on March 13, 2018.

Acquisitions	Note 8—Acquisitions Ringsouth Europa, S.L. On December 11, 2019, the Company's subsidiary, net2phone, Inc. acquired 100% of the outstanding shares of Ringsouth Europa, S.L. ("Ringsouth"), a business communications provider headquartered in Murcia, Spain. The acquisition expands net2phone's business into Spain. Ringsouth's operating results from the date of acquisition, which were not significant, are included in the Company's consolidated financial statements. The acquisition date fair value of the consideration consisted of the following (in thousands): Cash paid $ 450 Contingent consideration 375 Total fair value of consideration $ 825 The contingent consideration includes two potential payments to the seller of $0.4 million each, based on monthly recurring revenue targets to be achieved over a 36-month period and 48-month period. The second potential payment is not contingent upon meeting the target for the first payment. The fair value of the contingent consideration was estimated using discounted cash flow models and Monte Carlo simulations. This fair value measurement was based on significant inputs not observable in the market and therefore represents a Level 3 measurement. The impact of the acquisition's preliminary purchase price allocations on the Company's consolidated balance sheet was as follows (in thousands): Trade accounts receivable $ 142 Other current assets 21 Property, plant and equipment 84 Goodwill 1,437 Non-compete agreement (4-year useful life) 50 Customer relationships (7-year useful life) 130 Tradename (2-year useful life) 30 Deferred income tax assets 118 Other assets 10 Trade accounts payable (302 ) Accrued expenses (136 ) Other current liabilities (408 ) Other liabilities (351 ) Net assets acquired $ 825 The goodwill was assigned to the net2phone segment and was attributable primarily to Ringsouth's assembled workforce and expected synergies from the business combination. The goodwill is expected to be deductible for income tax purposes. The Company's pro forma results of operations as if the Ringsouth acquisition occurred on August 1, 2018 were not materially different from the actual results of operations. Versature Corp.

Earnings Per Share [Abstract]
Earnings (Loss) Per Share	Note 11—Earnings (Loss) Per Share Basic earnings per share is computed by dividing net income attributable to all classes of common stockholders of the Company by the weighted average number of shares of all classes of common stock outstanding during the applicable period. Diluted earnings per share is computed in the same manner as basic earnings per share, except that the number of shares is increased to include restricted stock still subject to risk of forfeiture and to assume exercise of potentially dilutive stock options using the treasury stock method, unless the effect of such increase is anti-dilutive. The weighted-average number of shares used in the calculation of basic and diluted earnings (loss) per share attributable to the Company's common stockholders consists of the following: Three Months Ended Six Months Ended 2020 2019 2020 2019 (in thousands) Basic weighted-average number of shares 26,320 24,816 26,300 24,323 Effect of dilutive securities: Stock options — — — — Non-vested restricted Class B common stock 131 — — — Diluted weighted-average number of shares 26,451 24,816 26,300 24,323 The following shares were excluded from the diluted loss per share computations: Three Months Ended Six Months Ended 2020 2019 2020 2019 (in thousands) Stock options 1,190 1,243 1,190 1,243 Non-vested restricted Class B common stock — 20 520 20 Shares excluded from the calculation of diluted earnings per share 1,190 1,263 1,710 1,263 In the three months ended January 31, 2020, stock options with an exercise price that was greater than the average market price of the Company's stock during the period were excluded from the diluted earnings per share computation. The diluted loss per share equals basic loss per share in the six months ended January 31, 2020 and in the three and six months ended January 31, 2019 because the Company had a net loss and the impact of the assumed exercise of stock options and the vesting of restricted stock would have been anti-dilutive.

On May 2, 2018, Jean Carlos Sanchez filed a putative class action against IDT Telecom in the U.S. District Court for the Northern District of Illinois alleging that the Company sent unauthorized marketing messages to cellphones in violation of the Telephone Consumer Protection Act of 1991. On July 26, 2018, the parties filed a stipulation of dismissal. The Company is evaluating the claim, and at this stage, is unable to estimate its potential liability, if any. The Company intends to vigorously defend this matter. On April 24, 2018, Sprint Communications Company L.P. filed a patent infringement claim against the Company and certain of its affiliates in the U.S. District Court for the District of Delaware alleging infringement of U.S. Patent Nos. 6,298,064; 6,330,224; 6,343,084; 6,452,932; 6,463,052; 6,473,429; 6,563,918; 6,633,561; 6,697,340; 6,999,463; 7,286,561; 7,324,534; 7,327,728; 7,505,454; and 7,693,131. Plaintiff was seeking damages and injunctive relief. On June 28, 2018, Sprint dismissed the complaint without prejudice. The Company is evaluating the underlying claim, and at this stage, is unable to estimate its potential liability, if any. The Company intends to vigorously defend any claim of infringement of the listed patents. On July 5, 2017, plaintiff JDS1, LLC, on behalf of itself and all other similarly situated stockholders of Straight Path, and derivatively on behalf of Straight Path as nominal defendant, filed a putative class action and derivative complaint in the Court of Chancery of the State of Delaware against the Company, The Patrick Henry Trust (a trust formed by Howard S. Jonas that held record and beneficial ownership of certain shares of Straight Path he formerly held), Howard S. Jonas, and each of Straight Path's directors. The complaint alleges that the Company aided and abetted Straight Path Chairman of the Board and Chief Executive Officer Davidi Jonas, and Howard S. Jonas in his capacity as controlling stockholder of Straight Path, in breaching their fiduciary duties to Straight Path in connection with the settlement of claims between Straight Path and the Company related to potential indemnification claims concerning Straight Path's obligations under the Consent Decree it entered into with the Federal Communications Commission ("FCC"), as well as the sale of Straight Path's subsidiary Straight Path IP Group, Inc. to the Company in connection with that settlement. That action was consolidated with a similar action that was initiated by The Arbitrage Fund. The Plaintiffs are seeking, among other things, (i) a declaration that the action may be maintained as a class action or in the alternative, that demand on the Straight Path Board is excused; (ii) that the term sheet is invalid; (iii) awarding damages for the unfair price stockholders received in the merger between Straight Path and Verizon Communications Inc. for their shares of Straight Path's Class B common stock; and (iv) ordering Howard S. Jonas, Davidi Jonas, and the Company to disgorge any profits for the benefit of the class Plaintiffs. On August 28, 2017, the Plaintiffs filed an amended complaint. On September 24, 2017, the Company filed a motion to dismiss the amended complaint. Following closing of the transaction, the Delaware Chancery Court denied the motion to dismiss. On February 22, 2019, the Delaware Supreme Court affirmed the denial of the motion to dismiss. The parties are engaged in discovery. The Company intends to vigorously defend this matter (see Note 9). At this stage, the Company is unable to estimate its potential liability, if any. In addition to the foregoing, the Company is subject to other legal proceedings that have arisen in the ordinary course of business and have not been finally adjudicated. Although there can be no assurance in this regard, the Company believes that none of the other legal proceedings to which the Company is a party will have a material adverse effect on the Company's results of operations, cash flows or financial condition. Sales Tax Contingency On June 21, 2018, the United States Supreme Court rendered a decision in South Dakota v. Wayfair, Inc., holding that a state may require a remote seller with no physical presence in the state to collect and remit sales tax on goods and services provided to purchasers in the state, overturning certain existing court precedent. The Company is evaluating its state tax filings with respect to the Wayfair decision and is in the process of reviewing its collection practices. It is possible that one or more jurisdictions may assert that the Company has liability for periods for which it has not collected sales, use or other similar taxes, and if such an assertion or assertions were successful it could materially and adversely affect the Company's business, financial position and operating results. One or more jurisdictions may change their laws or policies to apply their sales, use or other similar taxes to the Company's operations, and if such changes were made it could materially and adversely affect the Company's business, financial position and operating results. Regulatory Fee Audit The Company's 2017 FCC Form 499-A, which reports its calendar year 2016 revenue, related to payments due to the FCC, is currently under audit by the Internal Audit Division of the Universal Service Administrative Company. At January 31, 2020 and July 31, 2019, the Company's accrued expenses included $41.1 million and $44.7 million, respectively, for these regulatory fees for the years covered by the audit, as well as prior and subsequent years. Purchase Commitments At January 31, 2020, the Company had purchase commitments of $52.6 million, including the aggregate commitment of $50.5 million under the telecom services commitments described below. Telecom Services Commitments In May 2019, the Company entered into a Memorandum of Understanding ("MOU") with a telecom operator in Central America for among other things, termination of inbound and outbound international long-distance voice calls. The MOU is effective until June 30, 2020 unless superseded by the execution of a definitive agreement. The Company has committed to pay such telecom operator monthly committed amounts during the term of the MOU. The parties intend to draft and execute a definitive agreement as soon as practicable. In August 2017, the Company entered into a Reciprocal Services Agreement, as amended, with a telecom operator in Central America for a full range of services, including, but not limited to, termination of inbound and outbound international long-distance voice calls. The Company has committed to pay such telecom operator monthly committed amounts during the term of the agreement. The agreement's expiration date is September 15, 2020. In addition, under certain limited circumstances, either party has the right to terminate the agreement. Pursuant to the agreement, the Company deposited $9.2 million into an escrow account as security for the benefit of the telecom operator, which is included in "Other current assets" in the accompanying consolidated balance sheet based on the terms and conditions of the agreement. Performance Bonds The Company has performance bonds issued through third parties for the benefit of various states in order to comply with the states' financial requirements for money remittance licenses and telecommunications resellers. At January 31, 2020, the Company had aggregate performance bonds of $17.6 million outstanding. Company Restricted Cash and Cash Equivalents The Company treats unrestricted cash and cash equivalents held by IDT Payment Services, which provides the Company's international money transfer services in the United States, as substantially restricted and unavailable for other purposes. At January 31, 2020 and July 31, 2019, "Cash and cash equivalents" in the Company's consolidated balance sheets included an aggregate of $11.5 million and $13.2 million, respectively, held by IDT Payment Services that was unavailable for other purposes. FCC Investigation of Straight Path Spectrum LLC On September 20, 2016, the Company received a letter of inquiry from the Enforcement Bureau of the FCC requesting certain information and materials related to an investigation of potential violations by Straight Path Spectrum LLC (formerly a subsidiary of the Company and Straight Path) in connection with licenses to operate on the 28 GHz and 39 GHz bands of the Fixed Microwave Services. The Company has cooperated with the FCC in this matter and has responded to the letter of inquiry. If the FCC were to pursue separate action against the Company, the FCC could seek to fine or impose regulatory penalties or civil liability on the Company related to activities during the period of ownership by the Company.
