NEWPORT BEACH, Calif., September 27, 2005 -- Mindspeed Technologies, Inc. (NASDAQ: MSPD), a leading supplier of semiconductor solutions for network infrastructure applications, today announced that Vierling Communications GmbH is shipping its voice-over-IP (VoIP)-enabled GSM wireless gateway Ecotel VoIP based on Mindspeed’s Comcerto processors.

          Vierling’s Ecotel VoIP wireless gateway allows enterprise customers to provide cost-effective connections between their IP telephone systems and mobile radio networks. The gateway also enables mobile users to access the Internet, email and fax services. The Ecotel VoIP system delivers two to eight GSM mobile radio channels and is based on the session initiation protocol (SIP).

           “We combined Vierling’s expertise in mobile radio gateways for conventional telephone networks with Mindspeed’s Comcerto integrated VoIP system solution to develop the world's most advanced GSM gateway for VoIP environments,” said Anton Gloeckner, product manager for Ecotel VoIP.

           “We are pleased that Vierling selected our Comcerto voice processors for its innovative Ecotel VoIP GSM wireless gateway,” said Steve McClure, executive director of marketing for Mindspeed. “Vierling’s mobile radio gateway system is another example of the expanding market opportunity for our system-on-chip Comcerto voice and data processing solutions.”

          Mindspeed’s mixed-media Comcerto processing platform integrates an application control and signaling processor with a real-time media-stream processor to provide a deterministic architecture capable of scaling from data-only applications to full packet telephony capabilities operating on hundreds of voice channels. Comcerto processors can also be combined with open-source software applications to provide developers with an embedded platform for creating a wide variety of new services and capabilities.
