GLEN ROCK, N.J. -- RADVISION (Nasdaq: RVSN), a source of award winning, industry-standard products and technologies for real-time visual communications, today announced that Brasil Telecom has chosen its powerful viaIP™ platform as a major component in its new converged voice, Web, and video conferencing and communication offering for enterprises and broadband residential customers throughout Brazil.

Leveraging the viaIP’s carrier-grade IP architecture and standards-based interoperability with third party Web/voice conferencing platforms, Brasil Telecom (BrT) now offers multimedia communication services to both enterprise meeting rooms and desktops. BrT is also using this architecture to deliver video telephony services to their residential customers’ living rooms and home PCs over a broadband IP connection. The contract, won by SupportCom and fulfilled in part by RADVISION, closed in late Q3. The network went live in January, 2004.

“RADVISION has a strong record in providing visual communication solutions that enable service providers to roll out visual communications services to their enterprise and residential customers,” said Cesar Frantz, CEO of SupportCom. “The technical success of RADVISION’s FastWeb installation for residential and enterprise video telephony along with its strong track record in a number of service bureaus that offer managed videoconferencing services to enterprise customers, made them a natural choice. We are excited to enable Brasil Telecom to be the first carrier in Latin America to offer a visual communication solution of this scope.”

“Our new integrated video, audio and web conference solution - tvfone – has positioned Brasil Telecom as a multimedia service provider, with high quality and availability as well as attractive costs for our customers. RADVISION’s viaIP™ platform represents the best cost/benefit relation for Brasil Telecom. Another key element for the success of the project was the fast delivery and configuration of the equipment,” says Waldir Morgado, Brasil Telecom’s director of Products and Services.
