ARCH v Summary The Cisco IP telephony solution includes infrastructure components of the traditional IP network, as well as devices dedicated to voice. Cisco CallManager provides call processing for the Cisco AVVID IP telephony solution. Voice, video, and data gateway protocols are required for call routing and interoperability on a network that supports IP telephony. Cisco CallManager provides access to a variety of media resources, software- or hardware-based entities that perform media processing functions on the voice data streams to which it is connected. The primary Cisco IP telephony applications include Cisco Customer Response Solution, Cisco Conference Connection, Cisco IP Contact Center, and Cisco Unity.
