I am having CCM 4.2. I have created MRG list and associated the same with the device pool. DSP resources are from my Voice Gateway. I can see the transcoding profile get associated with the Call Manager.
I am using AutoAtendant with the help of the 5 seat IVR license coming along with CCM. I have created CTI Routepoint in the CCM for these applications.
Now calls to the these AutoAttendant are functioning properly from Phones which are in local LAN. But when I am calling from another site which is using G.729 codec , I am not able to call this number.
What could be problem ? I understand this could be a transcoding issue, but I have MRG list associated to my device pool, the DSP resources are also seen associated.
What Device Pool are the CTI ports using? make sure that they refeence the DP wich includes MRG with the transcoders. Try running "debug sccp" on the GW with the transcoding profie configured to look for more details.
Transcoders just work (99% of the time) when invoked. What would be helpful is to see the detailed CCM trace (with h245 and all gateway) for a call. You can then see if the transcoder is being invoked by CallManager or not.
You need to go to your CallManager's serviceability webpage then enable a CallManager detailed trace. This will be done via the web interface. Once you have a trace of a call that fails, paste the CCM000000xxx.txt file that has the call in it. Don't forget to turn on h245 and all gateway.
