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? Larry - N7FM
