- Altice One Selects Net2Phone to Market Cable Telephony Services
- Showcases international expansion of Net2Phone’s PacketCable-compliant solutions

Newark, NJ and Luxembourg - March 23, 2004 - Net2Phone Cable Telephony, LLC, (NCT) a wholly owned subsidiary of Net2Phone (NASDAQ: NTOP), and Altice One, a cable conglomerate and consolidator representing more than 500,000 homes passed, today announced that they have signed a binding term sheet, providing for the deployment of VoIP services by Altice over its existing cable infrastructure in Brussels, Belgium; Strasbourg area and Mulhouse, France; and Luxembourg, utilizing Net2Phone’s outsourced cable telephony solution. Net2Phone’s cable voice platform utilizes Cable Labs DOCSIS architecture and permits cable operators like Altice to deploy toll-quality residential telephone service over their existing cable infrastructure.

The parties are simultaneously working on a Definitive Agreement as well as systems engineering and planning. Altice will then deploy cable telephony service beginning in the fall of 2004 in all three markets (Belgium, France and Luxembourg).

“Partnering with Net2Phone for our telephony deployment will help us offer a strong triple-play service to key markets we serve: cable television plus high-speed Internet access plus phone service. In turn, that bundled offering will bring competitive advanced services to our customers,” said Patrick Drahi, CEO of Altice.

“This agreement with Altice is the next big step for Net2Phone as we advance toward our goal of becoming the turnkey voice solution for cable operators worldwide,” said Stephen Greenberg, CEO of Net2Phone. “We are extremely pleased that Altice has elected to partner with Net2Phone to provide telephony services to its customer base, and we look forward to additional growth in Europe, as we continue to grow our cable telephony business.”

Greenberg continued, “We’ve seen enormous success in VoIP internationally over the years, and this deal is a testament to the demand for telephony options in Europe. The international opportunity for cable telephony is enormous, and nobody is better positioned to capitalize than Net2Phone.”

Through the Net2Phone Cable Telephony model, Altice maintains ownership of the customer, service brand, and Tier I customer and technical support, while Net2Phone supports the back office Packet Cable infrastructure, switching and transport, ongoing operations and Tier II+ technical support to deliver a fully managed Quality of Service (QoS) IP solution. Net2Phone tracks and monitors voice quality and network performance metrics from start to finish and will provide Altice with a full view into telephone calls routed over its network. Altice customers will benefit from savings compared to the cost of their current phone service, in addition to receiving a bundled offering of cable TV, high-speed Internet access and telephone services.
