Cisco Cisco TelePresence Video Communication Server Expressway

Enabling endpoints registered on the video network to call MOC clients registered on OCS 

 

1.  On the DNS page (System configuration > DNS) set: 

 

Local host name to a unique hostname for this Cisco VCS 

 

Domain name to the domain name for this Cisco VCS 

2. Click 

Save. 

Note that the Local host name concatenated with DNS Domain name is the routable FQDN of this 
Cisco VCS. 

Note: If these are not configured and the connection between OCS and Cisco VCS is TLS, then 
although the neighbor zone goes active and Cisco VCS can send messaging to OCS, OCS will never 
open a TLS connection back to Cisco VCS, resulting in no calls OCS to Cisco VCS and other strange 
behavior. 

This should be configured whether the Cisco VCS is part of a cluster or not; this value is used with 
FindMe™ as well as clustering. 

For each “OCS gateway” Cisco VCS peer, ensure that Cluster name is the same, and is set up to be 
the FQDN of the cluster. Note that this should have been set up when the cluster was created – see 
“Cisco VCS Deployment Guide - Creating a Cluster of Cisco VCS peers (Cisco VCS X5) - D1436702”. 
If the cluster name needs changing follow the procedure in that document.
