Inbound dtmf problems

FreePBX Installation / Upgrade
1

Inbound dtmf tones are not recognized by the asterisk system. When I call from my AT&T phone and choose an ivr option nothing happens. Don’t know what I did wrong in setting up the trunk, but my trunk config is listed below. Please critique if needed. This problem is mainly with AT&T iphones. Everything else works fine like ext’s, ring groups, time conditions, etc.
I’ve tried auto, inband and rfc2833 dtmf modes and none work. But if I go back to a flat install of 1.4 it seems to work fine until I update it. The odd thing is that if I take this system back to my office and populate the trunk with my co’s sip info, it works fine?!?! we have the exact same pix f/w with the exact same config and the same sip carrier which is cbeyond.
Has anyone else had this problem? Is there a fix or work around?

thanks in advance and all info is appreciated!

Have you changed the ip in your /etc/asterisk/sip_nat.conf file?

The solution that we used to solve this problem is detailed here:

This should work with any FreePBX based setup. If you are still having this problem, hope it helps.
