CUBE: outbound SIP trunk disconnect on call pickup

[Martin Abildgaard]

hi all

have been looking for a resolution for this, but nothing has helped me.

I have a Cisco CUBE(2921) between the SIP provider and our UCM7.1.5.

Callflow: SIP-provider - SIP - CUBE - SIP - UCM

Inbound call works fine. Issue is outbound calls.

When the remote end picks up, the call is disconnected. If moving to H323 between CUBE and UCM the call works, but then there is no DTMF.

have verified that SIP trunk have MRGL and MRGL contains resources.

Attached is running config and debug from ccsip messages and voip ccapi inout

Any ideas?

Thank you.

Hi Martin

In the  dial-peer voice 1002 voip and  dial-peer voice 1001 voip which i think are the dial peers pointed to cucms you have configured  dtmf-relay h245-alphanumeric which is a pure h323 command.Pls remove it and put Dtmf-relay sip-notify or

dtmf-relay rtp-nte

Also for every voip dial peer remember to add no vad .Vad is bad.

Suggestions:

dial-peer voice 1001 voip

incoming called-number .

The above will handle calls coming from cucm to CUBE

Try all the above and return back with a feedback
