I have a customer who is running Callmanager 7.0(2) and would like to have the CCMUser web page use a certificate from thier internal CA.
Is this possible?
Yes. It's supported. You need to log into CUCM OS Administration web page > Security > Certificate Management > generate a CSR for Tomcat. Get the CSR to the CA and issue a cert.
See http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/security/7_0_1/secugd/sechttps.html for details.
