Segment Reporting [Abstract]
Business Segment Information	Note 2—Business Segment Information As of August 1, 2020, the Company revised its reportable business segments to reflect the growth of its financial technology and cloud communications businesses and their increased contributions to the Company’s consolidated results. The Company now has three reportable business segments, Fintech, net2phone-Unified Communications as a Service (“UCaaS”), and Traditional Communications. The revised reportable business segments reflect management’s approach to analyzing results, its resource allocation strategy, and its assessment of business performance. Comparative segment information has been reclassified and restated in all periods to conform to the current period presentation. The Company’s reportable segments are distinguished by types of service, customers, and methods used to provide their services. The operating results of these business segments are regularly reviewed by the Company’s chief operating decision maker. The accounting policies of the segments are the same as the accounting policies of the Company as a whole. There are no significant asymmetrical allocations to segments. The Company evaluates the performance of its business segments based primarily on income (loss) from operations. The Fintech segment comprises BOSS Revolution Money Transfer, a provider of international money remittance and related value/payment transfer services, and National Retail Solutions (“NRS”), operator of a nationwide point of sale (“POS”) retail network providing payment processing, digital advertising, transaction data, and ancillary services. BOSS Revolution Money Transfer and NRS were previously included in the Company’s Telecom & Payment Services segment. The net2phone-UCaaS segment comprises net2phone’s cloud communications offerings, which were previously included in the Company’s net2phone segment. The Traditional Communications segment includes BOSS Revolution Calling, an international long-distance calling service marketed primarily to immigrant communities in the United States, Mobile Top-Up, which enables customers to transfer airtime and bundles of airtime, messaging, and data to international and domestic mobile accounts, and Carrier Services, a wholesale provider of international voice and SMS termination and outsourced traffic management solutions to telecoms worldwide. Traditional Communications also includes net2phone-Platform Services, which provides telephony services to cable operators and other offerings that leverage a common technology platform, as well as smaller communications and payments offerings, many in harvest mode. Most of the Traditional Communications segment was previously included in the Company’s Telecom & Payment Services segment except for net2phone-Platform Services, which was previously included in the Company’s net2phone segment. Corporate costs include compensation, consulting fees, treasury, tax and accounting services, human resources, corporate purchasing, corporate governance including Board of Directors’ fees, internal and external audit, investor relations, corporate insurance, corporate legal, business development, charitable contributions, travel, and other corporate-related general and administrative expenses. Corporate does not generate any revenues, nor does it incur any direct cost of revenues. Operating results for the business segments of the Company were as follows: (in thousands) Fintech net2phone- Traditional Communications Corporate Total Three Months Ended January 31, 2021 Revenues $ 18,497 $ 10,738 $ 310,531 $ — $ 339,766 (Loss) income from operations (247 ) (3,248 ) 18,712 (2,294 ) 12,923 Three Months Ended January 31, 2020 Revenues $ 9,741 $ 7,915 $ 306,234 $ — $ 323,890 (Loss) income from operations (3,177 ) (3,787 ) 10,782 (2,495 ) 1,323 Six Months Ended January 31, 2021 Revenues $ 38,585 $ 20,366 $ 624,240 $ — $ 683,191 Income (loss) from operations 2,889 (7,059 ) 34,502 (4,158 ) 26,174 Six Months Ended January 31, 2020 Revenues $ 19,298 $ 15,122 $ 629,669 $ — $ 664,089 (Loss) income from operations (5,847 ) (7,495 ) 18,268 (4,996 ) (70 )

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 payments received for prepaid BOSS Revolution Calling. 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 sheets as “Deferred revenue”. The following table presents information about the Company’s contract liability balance: Three Months Ended Six Months Ended 2021 2020 2021 2020 (in thousands) Revenue recognized in the period from amounts included in the contract liability balance at the beginning of the period $ 22,818 $ 24,957 $ 26,451 $ 35,146 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. 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” $ 3,066 $ 2,350 Deferred customer contract acquisition costs included in “Other assets” 2,946 2,384 Total $ 6,012 $ 4,734 The Company’s amortization of deferred customer contract acquisition costs during the periods were as follows: Three Months Ended Six Months Ended 2021 2020 2021 2020 (in thousands) Amortization of deferred customer contract acquisition costs $ 864 $ 615 $ 1,631 $ 1,166

In the six months ended January 31, 2021, the Company repurchased 463,792 shares of Class B common stock for an aggregate purchase price of $2.8 million. There were no repurchases under the program in six months ended January 31, 2020. At January 31, 2021, 5.8 million shares remained available for repurchase under the stock repurchase program. Deferred Stock Units Equity Incentive Program The Company has an existing equity incentive program in the form of DSUs that, upon vesting, will entitle the grantees to receive shares of the Company’s Class B common stock. On January 5, 2021, the second vesting date under the program, in accordance with the program and based on elections made by certain grantees, the Company issued 283,838 shares of its Class B common stock in respect of vested DSUs. Based on those elections, vesting for 19,919 DSUs was delayed until January 5, 2022. At January 31, 2021, there were 154,169 unvested DSUs outstanding, all of which are eligible to vest (if the conditions therefor are satisfied) on January 5, 2022. 2015 Stock Option and Incentive Plan In the six months ended January 31, 2021 and 2020, the Company received proceeds from the exercise of stock options of $0.7 million and $0.3 million, respectively, for which the Company issued 81,041 and 32,551 shares, respectively, of its Class B common stock. Grant of Restricted Equity in net2phone 2.0, Inc. On December 31, 2020, the previously approved compensatory arrangement with each of Howard S. Jonas and Shmuel Jonas, the Company’s Chief Executive Officer, was finalized. Howard S. Jonas and Shmuel Jonas each received fifty restricted shares of net2phone 2.0, Inc. (“net2phone 2.0”) Class B common stock, which represents 5% of the outstanding common stock of net2phone 2.0. net2phone 2.0 is a new entity that owns and operates the net2phone-UCaaS segment. The restricted shares will vest if: (a) for any fiscal quarter of net2phone 2.0 between November 1, 2020 and October 31, 2023, net2phone 2.0 records subscription revenue that is at least $18 million, and (b) as of October 31, 2023, the valuation of net2phone 2.0 is $100 million or more. The restricted shares will also vest in the event, prior to October 31, 2023, net2phone 2.0 or its assets are sold at an equity valuation and on a cash-free basis of $100 million or more, regardless of whether the revenue threshold was satisfied prior thereto. The restricted shares entitle each grantee to proceeds only on a sale, spin-off, initial public offering, or other monetization of net2phone 2.0 and have protection from dilution for the first $15 million invested in the net2phone 2.0 following the grant. The aggregate estimated fair value on the grant date was $0.2 million, which will be recognized over the vesting period.

Earnings Per Share [Abstract]
Earnings (Loss) Per Share	Note 12—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 2021 2020 2021 2020 (in thousands) Basic weighted-average number of shares 25,362 26,320 25,448 26,300 Effect of dilutive securities: Stock options 9 — 4 — Non-vested restricted Class B common stock 342 131 335 — Diluted weighted-average number of shares 25,713 26,451 25,787 26,300 The following shares were excluded from the calculation of diluted earnings (loss) per share: Three Months Ended Six Months Ended 2021 2020 2021 2020 (in thousands) Stock options 1,035 1,190 1,070 1,190 Non-vested restricted Class B common stock — — — 520 Shares excluded from the calculation of diluted earnings per share 1,035 1,190 1,070 1,710 In the three and six months ended January 31, 2021 and 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 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.

Commitments and Contingencies	Note 14—Commitments and Contingencies Coronavirus Disease (COVID-19) The Company continues to monitor and respond to the impacts of the COVID-19 pandemic on all aspects of its business, including its customers, employees, suppliers, vendors, and business partners. Operationally, the Company’s employees transitioned to work-from-home during the third quarter of fiscal 2020 and, to a large degree, continued to work-from-home thereafter. Its salespeople and delivery employees continued to serve its independent retailers and channel partners with minimal interruption. COVID-19 had mixed financial impacts on the Company during the third and fourth quarters of fiscal 2020, and the first and second quarters of fiscal 2021. Legal Proceedings On January 22, 2019, Jose Rosales filed a putative class action against IDT America, IDT Domestic Telecom and IDT International in California state court alleging certain violations of employment law. Plaintiff alleges that these companies failed to compensate members of the putative class in accordance with California law. In August 2019, the Company filed a cross complaint against Rosales alleging trade secret and other violations. The parties are now seeking court approval of a settlement agreement. 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, which was ultimately denied, and which denial was affirmed by the Delaware Supreme Court. The parties are engaged in discovery. The trial is currently scheduled for December 6, 2021. The Company intends to vigorously defend this matter (see Note 10). 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 has evaluated its state tax filings with respect to the Wayfair decision and is in the process of reviewing its remittance 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 Fees Audit The Company’s 2017 FCC Form 499-A, which reports its calendar year 2016 revenue, is currently under audit by the Universal Service Administrative Company (“USAC”). The Internal Audit Division of USAC issued preliminary audit findings and the Company has, in accordance with audit procedures, appealed certain of the findings. The Company awaits a final decision by USAC on the preliminary audit findings. Depending on the findings contained in the final decision, the Company may further appeal to the FCC. Although a final decision remains pending, the Company has been invoiced $2.9 million and $1.8 million on behalf of the Federal Telecommunications Relay Services Fund and on behalf of the Universal Service Fund, respectively. The Company does not intend to remit payment for these fees unless and until a negative decision on its appeal has been issued. In response to the aforementioned preliminary audit findings, the Company made certain changes to its filing policies and procedures for years that remain potentially under audit. At January 31, 2021 and July 31, 2020, the Company’s accrued expenses included $41.1 million and $40.8 million, respectively, for FCC-related regulatory fees for the year covered by the audit, as well as prior and subsequent years. Purchase Commitments At January 31, 2021, the Company had purchase commitments of $1.3 million primarily for certain equipment and services. 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, 2021, the Company had aggregate performance bonds of $19.8 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, 2021 and July 31, 2020, “Cash and cash equivalents” in the Company’s consolidated balance sheets included an aggregate of $9.8 million and $11.0 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.
