November 18 1997

HACKENSACK, N.J.--(BUSINESS WIRE)--Nov. 18, 1997-- IDT's (NASDAQ: IDTC - news) Net2Phone today unveiled a corporate solution for Internet telephony with the introduction of Net2Phone 8.35 at Fall COMDEX 97. The solution enables corporations to fully integrate Net2Phone, IDT's proprietary Internet telephony service, into a PBX or standard telephone. Business and personal users will now be able to reap the benefits of low-cost Internet telephony without requiring a microphone or speakers. Those attending COMDEX will be able to test the newly integrated service at Net2Phone's booth (H844 at the Las Vegas Hilton).

Utilizing PhoneJACK - Quicknet Technologies' telephony expansion card with full PSTN emulation - a PC running Net2Phone can be plugged into either a PBX or a traditional single-line telephone resulting in transparent Internet phone calling. With Net2Phone 8.35, calls are initiated from a telephone and have full touch-tone decoding. Added features include conference calling, remote call forwarding, and transferring abilities.

``More than 290,000 customers worldwide have reaped the benefits of Net2Phone, and with this new dialing integration, we expect to attract a larger corporate clientele as well as increase our current residential customer base,'' said Net2Phone CEO Clifford Sobel. ``The ability to directly place a call from your telephone over the Internet using Net2Phone means that businesses can now take advantage of the Internet to make calls to save money on long distance and International calls.''

``By providing direct dialing and telephone integration between the Internet PhoneJACK and IDT's market leading Net2Phone, the customer's quality and calling experience are greatly improved,'' said Mr. Stacey Reineccius, President of Quicknet Technologies, Inc. ``Working together, IDT and Quicknet have now been able to bring a whole new level of ease of use, quality and affordability to the Internet telephone user.''

Because the computer is plugged into the PBX or telephone, the Net2Phone call appears as if it is originating on a telephone line as opposed to a computer. The Internet PhoneJACK can be connected directly to a telephone from a PC, resulting in a regular telephone conversation via Net2Phone. With powerful quality improving features including echo cancellation and on-board compression the Internet PhoneJACK is specifically designed to provide the best possible quality for Internet based voice calls.

In response to popular demand, IDT's Net2Phone also announced today plans to introduce significantly reduced Net2Phone rates for corporate users. New rate tables will be introduced for high-frequency callers by the end of 1997.

Those not attending COMDEX can download the FREE updates to version 8.35 of Net2Phone and version 1.3 of Internet PhoneJACK software in order to take advantage of the new integrated capabilities. (Both are available at www.net2phone.com and www.quicknet.net/download.htm)

This release is not to be confused with Net2Phone DIRECT, IDT's Internet long distance service where users do not need computers or an Internet connection to initiate a call.
