I have been using Teliax for a while with one iax2 trunk. We call out using a call file to remind people of appointments. They can push button 3 to recognize the appointment and then hangup.
For the past few days, dtmf has not been recognized by callers navigating through our custom contexts. Outbound dtmf works fine when calling a credit card company. I can hear the tones being generated if I simply make a call with a softphone.
Set up sipdiscount and vitelity trunks and the inbound dtmf works fine. Changed Teliax to sip trunk and still did not work.
I think I have proven that at least for me, Teliax is not allowing inbound dtmf recognition. Tried ulaw and gsm. Here is the sip config. Used nat=yes and had it deleted the line at one time as well.
