High Availability (HA) / Duplex Deployment
Issues/Limitations:
- Consult case popup on agent's number instead of the customer. For B always, it could also happen for A if we receive consult event first.
- The above issue affects activity for a record associated with the activity.
- Call Type internal for conference case as not able to track the origin of the call.
- Direct Transfer issue, null in connected number and no popup. As we get number from the call variable in this case.
- Call variables become null.
All issues are related to Call Data not being available after failover.
Cisco Documentation Link:Â Cisco Unified Contact Center Express Administration and Operations Guide, Release 11.6(1) - Unified CCX Introduction [Cisco Unified Contact Center Express] - Cisco
"If the active server fails, the Unified CCX provides automatic failover to the standby server. If the active server fails (for example, in the event a hardware failure occurs or the Unified CCX Engine process terminates), some calls being handled by the server are lost. The lost calls are restricted to those being handled by the system (those in the IVR stage or in the queue). Calls answered by agents continue to remain live even though related data on the agent desktop is lost. "
Note
The above issues/limitations are only for the current ongoing call on which failover occurs. For the next call, all the operations should be performed smoothly.Â
