I may be missing something, but it seems to me VoIP uses a 12 button keypad, not 16. Radios use 16, but they are not VoIP. What is it you are trying to do with the extra keys?
Thanks, Bob kk6ecm

If using IaxRpt control panel can anyone explain how to dial DTMF digits A,B,C,D?
I don't mean the propagation issue. I mean the keypad is only a 12 button keypad not a 16 key.
Anyone know a way to add the other 4 buttons (A,B,C,D) or send their tones as if they are being dialed from the keypad?
