Cisco Cisco TelePresence Video Communication Server Expressway
When nnnn@vcs.domain is dialed by an endpoint registered to Unified CM, Unified CM will route the call to
the VCS as nnnn@<FQDN of VCS>:5060 (TCP) or nnnn@<FQDN of VCS>:5061 (TLS). (The domain may
alternatively be the IP address of VCS, depending on what is configured as the SIP Trunk Destination
Address.)
the VCS as nnnn@<FQDN of VCS>:5060 (TCP) or nnnn@<FQDN of VCS>:5061 (TLS). (The domain may
alternatively be the IP address of VCS, depending on what is configured as the SIP Trunk Destination
Address.)
Calls can now be made from Unified CM to endpoints on VCS registered as 4xxx@vcs.domain.
