CUCM 15.0.1 with UCCX 12.5SU3 ES04 - Post Install Issue

[Eduardo Leon Dominguez]

Dear Collab Team,

Recently we deployed CUCM 15.0.1. After that I installed the last UCCX 12.5SU3 (12.5.1.11003-511) with the patches: ES04 and ES04_special. However I stucked with the post-install CUCM-UCCX integration step (Cisco Unified CM Configuration - Service Provider Configuration) When I introduce the CUCM HostName / IP Address and the AXL Admin CUCM UserName&Pass appear a AXL error message: "Cisco Unified CM Authentication Failed because of CCMAXL Exception. Please check the logs for details."

I've imported the CUCM Tomcat Certificates into the UCCX and all seems fine related the certificates. I see in Reddit exactly the same issue but installing the ES patch not work for me:

I have doubts about the UCCX 12.5 compatibility with CUCM 15. Can you help me with that issue? What's the workaround?

Thanks.

If I understand the documentation for ES04 special correctly you cannot have that installed if you intend to use CM 15.

Based on this I think you'd need to install ES04 again.
