Cisco Cisco Agent Desktop 8.0 Fehlerbehebungsanleitung

takes about 30 to 45 minutes (per node), and switching the versions takes about 10 to15 minutes. It is also
recommended that you perform these tasks after business hours.

Note: If the IPPA service does not connect after the upgrade to 8.5(1), assign an IP address to the system that
is less than 100 in the last octet (that is, XXX.XXX.XXX.XX) during implementation. This is documented in
Cisco bug ID CSCtn23610 (registered customers only) .

In order to resolve the issue, perform these steps:

Change the AXL provider of the Cisco Unified Contact Center Express using the set uccx provider
ip axl addr <The New IP address> CLI command.

1. 

In UCCX serviceability, go to Tools > Control Center−Network Services and restart the Cisco
Desktop Sync Service.

2. 

After a failover or the Unified Contact Center Express Engine restart, the slave server takes over. All the
services on the secondary server come up as Master. Also, IP Phone Agent (IPPA) clients have issues logging
in after Unified Contact Center Express failover. The agents receive this error message:

Cannot connect to the IP Phone Agent service

This issue is documented by Cisco bug ID CSCtt11421 (registered customers only) . In order to resolve the
issue, restart the Cisco Browser and IP Phone Agent service.

IPPA login takes a longer time, for example, 10−15 minutes. When saving changes for trace configuration via
GUI, this error is received:

Error occurred while saving trace configuration. Unable to save config data to

PropertiesConfig

When trace level is set from CLI, it works without any issue.

This issue is documented by Cisco bug ID CSCtz14497 (registered customers only) . The workaround is to
stop the Cisco Desktop VOIP monitor service on both the nodes.

On the Unified Contact Center Express server, IPPA agents cannot login after the server reboot. However,
restarting the IPPA service allows agents to login. BIPPA service IPPASvr causes a memory leak when CAD
services are running on an IVR/IPCCX server. This also leads to IPPA agents unable to login on the UCCX
server.
