[cisco-voip] MTP - application log error

[Scott Coner (US)]

Also be sure you specified the g.711 codec in your h.323 dial peers.

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?

	Hi 

	I am currently busy with implementation of IPt network. HQ with
ccm 4-1-3sr3a, couple of branches with ISR routers as h323 voice
gateways with local breakout via ISDN - to pstn. All phones register
with central CCM server. In general working fine. I noticed something I
am not sure about,  the application logg on the call manager shows
error; not enogh MTP resources - add more MTP- transcoding resources. 

	  

	At HQ we use G711, branches use g711 and branch to HQ and HQ to
branch calls use G729. As far as I am concerned we are not using any MTP
- the eventviewer in 2K also shows no MTP being used - so not sure why
the application logg errors. 

	  

	  

	No MOH in branches yet only unicast MOH at HQ 

	  

	Has anyone else seen this before. CCM4-1-3sr3a and OS2000-4-2
