Changing calling id / name for SIP URI calls to VCS

Hello,

I have CUCM 9.1 clusted with a SIP trunk to a VCS-C.  When making calls, the calls show a caller-id of extenstion@ip address, for exampe 2500@172.16.1.5.  I have a directory URI setup on the phone that is generating the call, but it's now showing the URI.  Inbound SIP URI calls are working fine.

 

Thanks

Sorry I know this is an old

Sorry I know this is an old post, but I think to resolve your issue you want to set the trunk destination to be the fqdn of the vcs-c. Simply changing from IP to FQDN actually makes the difference you're looking for. Just make sure you CUCM can query DNS. That will cover the domain portion of the caller-id being sent from CUCM to VCS.

Also under the outbound calls section of the trunk you then have the option to set the host portion of the caller-id to be DN or URI.
