Hi,
I have recently deployed CUCM 11.5 with Expressway-C & E with CMS and have a couple Telepresnence Video systems registered to CUCM. Directory numbers have been associated to the units and units are registered. when attempting to dial the DN i recieve the below when looking at the call logs:
This occurs on all endpoints that are registered. I have searched CUCM top to bottom trying to find a reason for this as well at the endpoint as it seems the CUCM is acknowledging the call but the receiving party may be rejecting it.
Any Ideas?
Thanks.

Did you happen to get a resolution to this issue? I'm having the same issue.
Thanks,

I got it figured out with TAC's assitance. As stated with this link, it had to do with the Subject name in my SIP Trunk security profile: https://supportforums.cisco.com/t5/telepresence/cms-video-conferencing-error/td-p/3092752
The issue I was seeing is that I'm using a wildcard certificate so I had to have *.domain.name in my Subject line on the SIP Trunk Security Profile
Thanks,
Tim

Should be noted that wildcard certificates aren't supported with the VCS/Expressway products, from the certificate creation guides:
Wildcard certificates manage multiple subdomains and the services names they support, they can be less secure than SAN (Subject Alternate Name) certificates. Expressway does not support wildcard certificates.

I couldn't agree more. This isn't expressways though, just CMS. Wildcards are supported on that platform.
Thanks,
Tim
