Feature Information for Video Conferencing

Configuring Video Conferences

This chapter describes the video conferencing support on Cisco Unified Communications Manager Express (Cisco Unified CME).

Finding Feature Information

Your Cisco Unified CME version may not support all of the features documented in this module. For a list of the versions in which each feature is supported, see the “Feature Information for Video Conferencing” section.

Prerequisites for Configuring Video Conferences

The following section contains information on the supported platforms and the requirements for configuring video conferences.

Platforms

This feature is supported on the following Cisco Integrated Services Routers:

  • Cisco 2900 Series
  • Cisco 3900 Series

The router with the DSP farm must have a PVDM3 module installed. See Table 19-1 for a list of the supported video service for the different PVDM3 modules.
