Newark, NJ -- September 25, 2001 -- Net2Phone, Inc (NASDAQ: NTOP), a leading provider of voice and enhanced services to IP networks, is currently making its Mail.com E-mail Service available, by hosting the corporate domain, for all companies that have been affected by the World Trade Center tragedy. This service, which will be provided for free, will allow any corporation and its workforce the ability to send and receive e-mail from their regular corporate e-mail addresses, through any web browser. The service will allow corporations to continue business as efficiently as possible, as they work from temporary offices and transition both their data and phone services to new and more permanent locations.

Net2Phone has been working in conjunction with the New York Software Association to make this service available to all of the companies that need it. Any company that is looking to sign up for the service or for more information on the service can find it at newyork.mail.com or by calling Adam Weissleder at (646) 223-1256.

"This tragedy has affected individuals, families, and companies in the tri-state area, all over this country, and around the world.," said Howard Balter, Chief Executive Officer of Net2Phone. "With on-going communications outages, we know how hard it has been for people to get back to work and return to a sense of normalcy. We hope that by providing this e-mail service we can make that process just a little easier."

Most communications networks have been affected by the events of the last two weeks, including traditional landline telephony, cellular phone service and data services. Net2Phone's VoIP network, along with e-mail communication were utilized as important communications tools in the wake of this horrific incident. Much of the landline and cellular service in the surrounding New York City area was knocked out and the Internet became the main connection to reach family, friends and co-workers. Both domestic and international usage on the Net2Phone VoIP network peaked in the hours directly after the initial attack. International calls into the New York City area over Net2Phone were roughly three to four times higher than the normal volume for most of the following week, as traditional phone service was still intermittent.

"It is very satisfying that our network was available to help people trying to reach their friends and loved ones during this difficult time," said Gary Lundner, Vice President of Network Operations. "Over the last several days, from a network standpoint, we can clearly see the incredible scope and power of the Internet and VoIP technology."
