Currently I'm tying in a single VCSc into a Cluster of 3 CUCM servers. I'm using the following guide as a template for the integration Cisco_VCS_and_CUCM_Deployment_Guide_CUCM_6-1_7_8_and_X7-1. In Appendix 5 it talks about how to do this when there are more than 1 CUCM server in your environment. There are 2 methods which really are not to different from one another where you must "Quote"
Set the Cluster Fully Qualified Domain Name to the same domain as the video network, for example vcs.domain. This parameter defines one or more Fully Qualified Domain Names (FQDNs) for this cluster. Multiple FQDNs must be separated by a space. Requests containing URLs (for example, SIP calls) whose host portion matches any of the FQDNs in this parameter will be recognized as a request destined for this cluster and/or devices attached to it.
My question is "What impact will this have on the CUCM Cluster?"
In my situation. CUCM FQDN =
My VCS endpoints are using a domain called
So if I change this parameter to match vc.example.com as it instructs to do so in the guide how will this effect other DNS dependancies for CUCM
CUCM also has other SIP integrations asside from VCS for example Exchange 2010 for Voicemail how will changing this setting affect other services
