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) )
Figure 12-3 shows a basic video deployment using Cisco RSVP Agent.
