Telemig Celular Selects Veraz to Optimize Bandwidth Between Mobile Switching Centers.

SAN JOSE, Calif. -- Veraz Networks, Inc. (NASDAQ:VRAZ), a leading global provider of IP softswitches and media gateways, has been chosen by Brazilian mobile operator, Telemig Celular, to optimize the bandwidth between Telemig's Mobile Switching Centers (MSCs). The deployment of Veraz's I-Gate 4000 media gateways has resulted in a reduction of bandwidth between switching sites by a ratio of up to 16 to 1 which has helped Telemig reduce both operational and capital expenditures.

"Prior to selecting Veraz, we conducted a comprehensive review of competing solutions, looking specifically at impact on profitability, return on investment, and reduction of capital and operational expenditures over time," said Paulo Matos, Director of Engineering of Telemig Celular. "The savings generated by Veraz's media gateways has been very impressive and has helped us become more competitive in our market."

The Veraz I-Gate 4000 media gateways use VoIP to transport and optimize the voice signals between Telemig's MSCs while maintaining excellent voice quality. In addition to bandwidth optimization, because the Veraz solution is built on an open standards-based architecture, it allows for a smoother migration to a full NGN or IMS solution. Operators can implement Veraz media gateways for applications today and benefit from their flexibility tomorrow as their needs evolve.

"Telemig Celular is widely recognized as an efficient and innovative company with the highest standards of excellence," said Carlos Linares, Vice President of CALA for Veraz. "We, at Veraz take great pride in having Telemig as a client and look forward to helping it to meet its challenges now and in the future."
