Solved: CME/CUE - sip trunk, no dtmf

dbauman_wan · ‎01-09-2010

Greetings,

When placing calls to a CUE AA over a SIP Trunk (from a Broadworks platform), dtmf doesn't make it through.

I've played around with the dial-peer settings, but have had no luck.

dtmf-relay sip-notify
dtmf-interworking rtp-nte

b2bua

Is there anything else I should be looking at?

Thanks,

David

Try

Gateway# voice service voip

Gateway# allow sip-to-sip

You may need to transcode the stream between sip trunk and CUE
Codece used by CUE is G.711.

sip to sip and all options are there.

I am using g711ulaw on the sip trunk. Can you send information about the transcoding?

When I try to put this config under telephone-service (sdspfarm tag 1 XCODE123456), I get this error:

Can't change name for registered mtp

mightyking · ‎01-10-2010

You need to use the name that you have given to your gateway. XCODE123456 is just an example.

"gateway" being my sip trunk provider in sip-ua?

mightyking · ‎01-10-2010

You need to use the name of the router where the DSP's are located. In your case, it would be the name of the CME.

Thats what I originally thought, but was still giving me the same error.

mightyking · ‎01-10-2010

What error message do you get?

MK

dbauman_wan · ‎01-12-2010

"Can't change name for registered mtp"

mightyking · ‎01-12-2010

Instead of " XCODE123456" in the above example, use the name that you have given to MTP and reset the SCCP by doing the following:

Gateway# no sccp

Gateway# sccp

I never gave it XCODE123456, but will definately try and removing sccp and re-adding it.

Thanks!
