[cisco-voip] Event Viewer Application Log Errors

[Kevin Thorngren]

There are no simple answers to either of these messages.

The MtpNoMoreResourcesAvailable message means that CCM tried to invoke 
a Transcoder or MTP device during a call and there wasn't one 
available.  This could be due to a Transcoder or MTP device 
unregistering, the device has used all its resources which means you 
will want to consider adding another or it could be that one of the 
devices involved in the call doesn't have the resources assigned.  
Typically this will result in the call being dropped, depending on what 
is requesting the resources.  For example, I have seen before where MoH 
is being invoked to a device across a WAN and the MoH steam needs to be 
G.729.  If G.729 has not been enabled for the MoH server and there is 
no Transcoder available then the MtpNoMoreResourcesAvailable message 
will appear but the call won't drop (you just won't hear MoH).  CCM 
traces are the best thing to look at when this occurs.

Devices will abnormally unregister to CCM due to network related issues 
or CPU issues on the Primary CCM causing missing SCCP KeepAlives.  
Again CCM traces are a good place to start.   This recent thread 
discusses initial troubleshooting steps for unregistering devices by 
looking at the "Last=" information from the phone when it registers to 
its secondary CCM.

Make sure to enable Detailed CCM traces on all nodes in the cluster.  
Then when one of these errors occurs gather the traces from that time 
frame.  If you are not familiar with the traces then maybe someone on 
this list will have time to help or you can open a TAC case to review 
the traces.
