[cisco-voip] MTP - application log error

[Kevin Thorngren]

Hi Erik,

There are many reason why this could happen.  Someone would need to 
look at the CCM traces to see what is really happening but here are a 
couple of ideas that won't actually cause call failures:

- MoH to a G.729 Region where there is no Transcoder and the G.729 
codec is not selected in the IPVMSA service parameters (you mentioned 
no MoH to the branches so this might not be the case).
- A failure to allocate a transcoder when the annunciator is invoked.  
Do you hear the annunciator when placing calls that fail or do you just 
hear reorder?
