Video

Cisco CUCM supports video calls between SCCP, H.323, and SIP endpoints.

CUCM can support point-to-point video calls between endpoints, and it supports video conference calls by taking advantage of Cisco IP/VC 3500 multipoint control units (MCU) and Cisco IP/VC 3500 H.320 gateways. CUCM supports a variety of video endpoints including Cisco 9971 IP phones, Cisco Unified Video Advantage endpoints, Cisco Unified Personal Communicator, Tandberg video conferencing endpoints, H.323 enabled clients (Tandberg, Polycom, Sony, and so on), and certain SIP endpoints.

CUCM 7.x includes Intelligent Bridge Selection, which enables CUCM to select conferencing resources based on whether the endpoints involved in the conference are video enabled. If two or more of the endpoints are video enabled, videoconferencing resources are selected (assuming that they are available). If there are no video-enabled endpoints or videoconferencing resources are not available, an audio conferencing resource is chosen.
