High Availability with IPCC Express Gateway
In high availability, there is a Side A PG installed on each of the two nodes of Unified CCX.
Only one of the servers, the Master, is active at a time. When the active side fails, the standby
side starts up, but all the calls in queue are dropped and the now-active server and PGs go
through a full re-initialization. (For more information on the Unified CCX Master Server, see
the Cisco Unified CCX Administration Guide.)
