Server certificate requirements for Unified Communications
Cisco Unified Communications Manager certificates
The two Cisco Unified Communications Manager certificates that are significant for Mobile and Remote
Access are the CallManager certificate and the tomcat certificate. These are automatically installed on the
Cisco Unified Communications Manager and by default they are self-signed and have the same common
name (CN).
Access are the CallManager certificate and the tomcat certificate. These are automatically installed on the
Cisco Unified Communications Manager and by default they are self-signed and have the same common
name (CN).
We recommend using externally-signed certificates for best end-to-end security between external endpoints
and internal endpoints. However, if you do use self-signed certificates, the two certificates must have
different common names. This is because the VCS does not allow two self-signed certificates with the same
CN. If the CallManager and tomcat self-signed certs have the same CN in the VCS's trusted CA list, then it
can only trust one of them. This means that either secure HTTP or secure SIP, between VCS Control and
Cisco Unified Communications Manager, will fail.

VCS certificates
The VCS certificate signing request (CSR) tool prompts for and incorporates the relevant subject alternate
name (SAN) entries as appropriate for the Unified Communications features that are supported on that VCS.
