Gigaset A510IP with CUCM v7

[ScottEmick]

I have sucessfully set up sip connections using my android phone and my obi-100 ata with the CUCM v 7 at my work, but now that I have set up my Gigaset system, I can get incoming calls ok, but I cannot make any calls. After dialing the 4 digit number, the dial tone stays on and after a long time I get a busy signal. It is like it is missing some kind of termination signal or something.

I tried to create a custom diak plan that matches the exact extension, I created 4907 to call extension 4907. This didn't help at all. (I have callcentric on SIP profiles 1 and 2, my work sip is on IP3.) When I place the call it does show going on IP3. I tried to change the DTMF signalling to every option because CUCM is using G.711 ulaw which is in-band DTMF signalling, but that doesn't seem to help either.

If anyone else has gotten this to work, I'd love to hear how you did it. The dial plans are so limited on this as well I cannot enter any wildcards it seems, so I don't know how I'm going to tell it that 4XXX and 8XXX calls need to go to SIP3.

Thanks
Scott

The dial plan of just entering the 4 digit extension works now. The problem is, the CUCM is not getting the DTMF. I've tried Media Termination Point Required, Require DTMF reception, and also I've tried to force various different codecs, but the CUCM never seems to get the touch tones.
