13.2 Cisco Unified Communications Manager and Cisco VCS Interconnection

This topic provides an overview on how to interconnect Cisco Unified Communications Manager and Cisco TelePresence Video Communication Server (VCS).

  • Cisco Unified Communications Manager and Cisco VCS Control are interconnected via a SIP trunk
  • Cisco VCS Control requires the following option keys:
    1. Traversal calls
    2. Nontraversal calls

Cisco Unified Communications Manager and Cisco VCS Control are connected by a SIP trunk.

In the example, endpoints in Cisco Unified Communications Manager and in Cisco VCS use the same domain (hq.cisco.com). If the destination of a call that is placed to an endpoint with this suffix is not found locally, the call is routed to the other system over the SIP trunk.
