Cant get DTMF to register from outside callers to the IVR. I have tried all the dtmfmode settings and forced the codec to ulaw & alaw. I also set debug to 99. I see DTMF events when I use an internal phone but not external. I also setup wireshark and it appears that RTP DTMF packets aren’t even coming in. BUT if I am on the phone with an outside caller and they press the buttons I hear them.
Our trunk provider is ringcentral.com. Do you suppose they are stripping out the DTMF? Do I have any options?
using Asterisk Now with Asterisk 1.6 and FreePBX 2.7
Thanks
