Net2Phone and Liberty Cablevision of Puerto Rico Reach Consumer Milestone
1,000th customer installed and provisioned with cable VoIP services

Newark, NJ and Luquillo, Puerto Rico - March 9, 2004 - Net2Phone (NASDAQ: NTOP) Cable Telephony, LLC and Liberty Cablevision of Puerto Rico, Inc. today announced the installation and the provisioning of the 1,000th cable telephony customer within Liberty Puerto Rico’s footprint since the formal launch of Net2Phone’s outsourced residential telephone service in mid-December, 2003.

Achieving this milestone showcases the demand, scalability and technical viability of Net2Phone’s service. Liberty Puerto Rico has deployed “VoiceLinks” in three municipalities in eastern Puerto Rico, offering consumers local, long distance and international phone service, including features such as call waiting, caller ID, directory assistance, and 911. Consumers receive one unified bill for all of Liberty Puerto Rico’s services.

Net2Phone’s back office systems integrate with Liberty Puerto Rico’s network operations center, provisioning software and customer service software, enabling Liberty Puerto Rico’s existing staff to support telephone service along with high-speed Internet and video services.

“The success of our telephony deployment has exceeded our expectations,” said Jose Alegria, General Manager of Liberty Cablevision of Puerto Rico. “We are leveraging our existing infrastructure and personnel - even our installers - to add phone service to our robust and valuable data and video product mix. Net2Phone has done a tremendous job of integrating their components with our existing systems to make the rollout of phone service seamless to our team.”

Net2Phone is continuing its strategy of empowering cable operators with the tools to provide residential phone service to its subscribers utilizing existing cable networks. Through the Net2Phone Cable Telephony model, Liberty Puerto Rico controls the service brand and Tier I customer and technical support, while Net2Phone supports the back office Packet Cable infrastructure, switching and transport, and Tier II+ technical support to deliver a fully managed Quality of Service (QoS) IP solution.

“The metrics speak for themselves - more than 1000 minutes of use per subscriber per month showcases the quality and reliability of the service,” said Stephen Greenberg, CEO of Net2Phone. “This deployment demonstrates that outsourcing telephony to Net2Phone - the VoIP experts who have been doing this longer and better than anyone else - is a wise move for any operator looking to quickly and efficiently deploy residential phone service and round out the triple play. We look forward to continuing to roll out to Liberty Puerto Rico’s entire footprint.”
