I use Cisco Unity Connection version: 188.8.131.5200-56.
When i Sign into Cisco unity connection i see this message :
The Cisco Unity Connection cluster subscriber server has changed to Primary Status (failover has occurred). To review server status for the cluster, go to the Tools > Cluster Management page of Cisco Unity Connection Serviceability.
Now the subscriber server is Primary server.
In this case is not possible for the caller to leave a message for more than 40 Sec.
I changed Publicher Server to Primary Server.
In this case is not possible for the caller to leave a message for more than 10 Sec.
Class of Service -> message length = 300
Solved! Go to Solution.
Time to grab some logs my friend.
Enable the Macro Traces and then replicate the issue.
You'll probably need Call Control (Miu) Traces (expand the macro trace to select SIP or SCCP) and Call Flow Diagnostics
Collect logs from RTMT (Collect Traces) - Connection Conversation Manager.
