> Hello,
> 
> Has anyone done a regular Unity integration with a CME before?
> 
> Have Unity 4.0(5) with Unity TSP version 8.2(1)  going to a CME 4.1
> system (12.4(15)T1) and MWI works, but the Unity servrer is getting
> the constant warning in the event logs every few seconds and it
> causing high CPU usage upwards of 40 to 50% all the time on the
> AvCsMgr service.The Unity AvCsMgr diagnostic log file is full of MWI
> attempts, and in the AvNotifer diag log file it has MWI attempts to
> and always saying NO RESOURCE as reason code.
> 
> Server and router have been rebooted (before I got involved in this)
> and did not help. Users are not complaining of MWI issues, and the
> extensions in these warnings exist on the router and the phones work
> fine.

> I got a TAC Case open also ..

> Description:
> 
> Cisco Unity-CM TSP device 15 (Cisco Unity port 11): An attempt to turn
> ON the message waiting indicator (MWI) for extension 4821 failed
> because a collision occurred with an incoming call on the same port.
> 
>  The MWI request will be retried. But to prevent collisions, we
> recommend that ports setting MWIs be isolated from ports handling
> incoming calls. If the MWI status remains unchanged for an extended
> period of time or if there are many of these warnings from Cisco Unity
> in a short period of time, there may be an MWI misconfiguration or
> another problem.
> 
> For more information, refer to the "Message Waiting Indicators"
> chapter in the Cisco Unity Troubleshooting Guide.
