Sierra Wireless is interested in harnessing the power of emerging Voice-Over-Internet Protocol (VoIP) technology in conjunction with their existing Wireless Wide Area Network (WWAN) modems. The goal of this Clinic project is to develop a VoIP over WWAN Gateway prototype that will interface with a normal analog phone receiver and a PC. The gateway will provide VoIP service and Internet access wirelessly via the Sierra Wireless WWAN modem.
