I'm looking for a solution for DX80 stations we have in use. The application/request is being able to trigger DTMF tones during a call without using the on screen pop up menu. Tones will be needed at random intervals and the pop up both get's in the way of viewing the call and times out too often. I'm looking for a simple USB keyboard or keypad solution and someone knowledgeable on writing macro's (not my area of expertise) . We've considered a 3rd party controller but that seems a bit extensive/expensive to do nothing but trigger the '1', '2', and '3' tones for DTMF. If someone could point me in the right direction I'd appreciate it.
