Cisco Unified Presence 9.x

[phonedude2]

We are in the process of designing a CUCM 9.x cluster with HA. All components and application must have the highest availability. CUCM and Unity Connections has failover and replications, however I haven't been able to find information on whether Unified Presence have this capability. Can Presence be designed to support a primary and secondary server, and when the primary goes off/line or is down the secondary takes over. This is not a supercluster, will only have 1 pub and 5 subs.

Presence supports HA and it is defined step by step in the installation and administration guide for how to set up properly. It requires specific srv records on your DNS which is also in the guide.

Currently all cisco UC apps support HA with no exception.
