[cisco-voip] UCCX 11.5 Upgrade Disaster

[Anthony Holloway]

It was version 11.5 which brought Tomcat to ECDSA certs and is causing
those new challenges, so you wouldn't have seen the same issues as Greg.

"Note: When you use UCCX 11.5 and later, there is a new certificate for
tomcat-ECDSA. When you use CA signed certificates, ensure that the CSR is
downloaded for this certificate as shown previously and the application
certificate for tomcat-ECDSA is uploaded into the tomcat-ECDSA as explained
in the previous procedure. This is required for the Live Data functionality
which uses Socket IO from UCCX 11.5"
