Office Phones (VoIP)

Case Western Reserve University utilizes both Analog / VoIP phones and Centrex phones.

Voice over IP (Voice over Internet Protocol or 'VoIP') technology converts voice calls from analog to digital to be sent over digital data networks. This allows Case Western Reserve University to use its existing data network (which includes fiber or copper wiring between and within buildings, and Cisco routers and switches) to transport telephone service throughout the campus. By offering Voice over IP, or VoIP, Case is moving toward a 'converged' network, where voice, data, and video all travel along the Case gigabit network. The Voice-over-IP based campus telephone system supports analog devices, gateways to public switched telephone network (PSTN) and long distance.

Analog phones take an audio or video signal and translate it into electronic pulses. These lines support standard phones, fax machines, and modems.
