We have a strange problem occurring within our enviornment.
We currently have one cluster with two CallManagers along with two Unity Servers in fail over scenario.
The fail over server was recently installed, along with the install we upgraded the primary Unity box from 3.1.4 to 3.1.5, the fail over server is at 3.1.5. CalManager 3.1.3
The problem is; Both Unity Systems are trying to take control of the Ports, creating a ping pong effect. This can be seen in the logs. Has anyone seen this problem?

Any chance you give each TSP the same port names? They should get separate, unique port names.

Yeah, they should be different. There's an obscure reference to this in the integration guide here...
It says, "In the Cisco CallManager Administration, a second voice mail server is required to serve the secondary server. This voice mail server must have a different name from the voice mail server that serves the primary server"
I think that the "server" it is referencing here is what is entered during the voice mail port wizard. Like Keith mentioned, they have to be unique.

Okay.. Just to make sure that I am on the same page with you..
Within CallManager; 'Cisco Voice Mail Port Configuration' The CIsco Voice Mail Ports should have different names from CallManager1 - CallManager2?
Thanks...

Not really. Within a CallManager cluster the port will be replicated to all nodes. You don't need to manually add them to each node.
Each Unity needs it own ports in CallManager. They don't share the same ports. So if I had 2 4 port Unity servers I would need something like this for the ports.
Unity1-VI1 DN:1000
Unity1-VI2 DN:1001
Unity1-VI3 DN:1002
Unity1-VI4 DN:1003
Unity2-VI1 DN:1004
Unity2-VI2 DN:1005
Unity2-VI3 DN:1006
Unity2-VI4 DN:1007
Is that what you have already?

Keith,
Our configuration is set as follows..
Unity1
CiscoUM1-VI1:1340
CiscoUM1-VI2:1341
CiscoUM1-VI3:1342
CiscoUM1-VI4:1343
Unity2
CiscoUM1-VI1:1340
CiscoUM1-VI2:1341
CiscoUM1-VI3:1342
CiscoUM1-VI4:1343
The DN's are the same, should they be different?
Thanks for your help!

Well the entire ports are the same. You need to make a second set of ports for the failover Unity server. They both can't use the same ones. This is why you are seeing these problems.
CiscoUM1-VI4should be setup to do only a Call Forward No Answer (CFNA) to the first port of your new group.

Keith,
Thanks for your help. I configured as you said, and Fail Back works fine.
