Posted on by

CUCM Failover with Cisco UAC Advanced in HA mode.

Scenario.

Two CUCM Subscribers with two Cisco UAC Servers in HA Mode. Each CUAC Server is required to be configured to connect to a difference CUCM Subscriber.

The Cisco UAC always uses the Primary UAC Server for CTI Registration, Triggers, Operator Logins etc. The Secondary UAC Server is in a Standby state.

To ensure CUAC continues to operate as per normal when a CUCM Server fails or is restarted, the below checkbox needs to be checked for both CUAC Servers. This allows each CUAC server to connect to both CUCM Subscribers.

Summary

1. The primary and secondary CUAC server connect to different CUCM Servers.

2. Ensure the “Add secondary CUCM information from other server” is checked.
