Explanation

When Cisco UCM is the primary call controller and Cisco VCS Control needs to communicate with it (for example, to route video calls to endpoints registered on UCM), a Neighbor zone (C) is created in VCS Control pointing to UCM. A Neighbor zone is used between two trusted systems on the same network that communicate directly. A Traversal Client zone (A) is used when VCS must traverse a firewall outward to reach a traversal server. A Traversal Server zone (B) is used when an external device initiates firewall traversal inbound to VCS. A DNS zone (D) routes calls by looking up DNS SRV/A records and does not represent a direct UCM integration point.
