Discovering Unified CM servers
1. On Expressway-C, go to
Configuration > Unified Communications > Unified CM servers
.
The page lists any Unified CM nodes that have already been discovered.
2. Add the details of a Unified CM publisher node:
a. Click New.
b. Enter the Unified CM publisher address.
b. Enter the Unified CM publisher address.
You can enter an FQDN or an IP address, but we recommend using the FQDN when TLS verify
mode is On.
mode is On.
c. Enter the Username and Password of an account that can access this server.
Note: These credentials are stored permanently in the Expressway database. The corresponding
Unified CM user must have the Standard AXL API Access role.
Unified CM user must have the Standard AXL API Access role.
d. [Recommended] Leave TLS verify mode switched On to ensure Expressway verifies the node's
certificates.
The Unified CM node presents its tomcat certificate for AXL and UDS queries, and its CallManager
certificate for subsequent SIP traffic. If the Unified CM server is using self-signed certificates, the
Expressway-C's trusted CA list must include a copy of the tomcat certificate and the CallManager
certificate from every Unified CM server.
