Try turning off video on the jabber device in CUCM. See if it works. If s, You can also use a SIP Normalization script on the trunk, or a sip profile tied to the dial-peer to remove video

Calls from any of our Cisco deskphones, and a small volume of users we have on MS Teams Voice, who also route out via Gamma using Direct Routing, can connect with no problems, as do calls from our mobiles.

I’ve set my Jabber client to not “Always start my calls with video”, but this didn’t change anything, and it’s notable that I’m successfully placing calls to the problem number from a Cisco 8865 handset that is also video enabled and sends similar video SDP information.
