Hello Friends,

We are having issue in call forwarding option in Cucm. when we try to forward any call on external DN, call is being answered but both party can not hear each other.

1. internal forwarding is ok only problem with external forwarding.

2. we are using call manager 7.5 and we have Cube for exit the external calls.

3. it is an intermediate issue as well , some time it work well and some time does not well for each site , which are configured in this cluster.

Call flow ---- PSTN---(sip)-----CUBE-----(sip)----CUCM-----(phone)

This could be caused by a number of things. Most likely causes are:  inability to negotiate a codec and/or inability to route RTP between endpoints.

Can you provide  debug ccsip message output of a failed call to see what is going on.

cheers

Hi,

When you face the problem, please share the following

1. From CUBE, get the command show active call voice brief. Indicate the calling and called numbers

2. From CUBE Try to ping the IP and and ITSP using the right source IPs.

3. From CUBE, share the command show sccp connection

4. From CUBE, debug ccsip mess

5. From CUCM, try to get RTMT Realtime Trace

Please put the debug in separate file to be able to read it properly.
