Chapter 12 IP Video Telephony Configuration

Cisco Unified CallManager Configuration for IP Video Telephony

In addition to Cisco RSVP Agent, you can use Cisco Unified CallManager region and location settings to establish video bandwidth for a call. However, with the introduction of RSVP agent in video call, the following rule is required to establish the bandwidth for a video call:

end-to-end video region = minimum of (region (A,agentA), region(agentA,agentB), region(agentB,B) and region(A,B) )

The following configuration was used for the Cisco RSVP Agent. The codec pass-through allows the audio transcoding of a video call:

dspfarm profile 2 transcode codec pass-through

codec gsmfr codec g729ar8 codec g729abr8 codec g711ulaw codec g711alaw rsvp

maximum sessions 8 associate application SCCP
