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

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?
01-10-2010 05:31 PM
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.
01-10-2010 06:32 PM
What error message do you get?
MK
01-12-2010 05:57 AM
"Can't change name for registered mtp"
01-12-2010 12:41 PM
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!
