ip phone ---- CME ------ CME ---- ip phone --> Successful
ip phone ---- CME ------ CME ---- CUE --> Fail
If I change the Codec to G711ulaw, it works fine, successful on both. But if I change it to ILBC, which I want to run on my excessivly low bandwidth WAN link, it fails when the call is forwarded to voice mail. I have seen multiple questions that were answered with, just change to G711, and this fixes everyones issue. I know G711 works, I want ILBC to work.
Solved! Go to Solution.

alright, however your issue seems to be with a transcoder, Check on the SITEB status of the show SCCP
TCP states?
Transcoding Oper State: ACTIVE_IN_PROGRESS - Cause Code: TCP_CONN_ERROR
Active Call Manager: NONE
on both CME run below command
# no sccp
#sccp
and check again the status of the xcoder? if possible i would sugesst try to re-configure xcoder fro scratch.
use this as reference for configuration for transcoder

Do let me know if you if stuck anywhere

Hello Clark,
CUE by default works on G711 codec,that's why it works for you when you change the codec.
Do you have a xcoder configured to stream one audio to another?

I think I configured the xcoder correctly, see below, IP address listed is the IP address of the router local interface, is it supposed to be the IP address of the CUE?

Hello Clark
Here is the issue, Your xcoder is not working due to TCP connection is not established and error, due to which xcoder is not getting invoked and calls are getting failed due to codec mismatch as no one there to stream the audio from one to another.

Each site has its own CUE. They are not sharing.

You were right, improperly configured the transcoder. I checked the web link you provided, but it was a little difficult to understand, so I searched for transcoder configurations and found this one:

Dropped this on the routers and everything popped up working with no issues. Thanks again for your help.
