I don't think you will get anywhere with that unless you edit the source code. There is no provision for it in ACID anyway that I have ever seen. But I think for the nature of the problem, it is easier solved by fixing problems with audio. Distortions can occur when 'flat topping' so to speak.(to hot) This often causes the double digits because the distortions make enough valid 'break length timing' of a digit. From where is something you need to look into With both your rx audio as seen in dsp and the radio's 'dtmf tx audio level' that is normally adjustable internally. (or both) but if you should change the source code, adjust the time of 'break length'. The time required of silence between the digits before the next digit. The reason adjusting that can problematic for some is the auto-send dtmf strings many use in their radios are pretty quick. My advise is play with the audio first. The dtmf timing has been well thought out. Adjusting it will have implications you did not account for. ...mike/kb8jnm ----- Original Message ----- From: "Users of Asterisk app_rpt" <app_rpt-users@lists.allstarlink.org> To:<app_rpt-users@lists.allstarlink.org> Cc: Sent:Sat, 11 Mar 2017 14:34:17 -0800 Subject:[App_rpt-users] DTMF timing Hi all, I’m having an issue with certain portable radios where the DTMF tones seem to be ‘bouncing’, i.e. a single tone is decoded multiple times for one press. The simple answer is “Buy a better radio!”, but that’s way too easy. The question is: Is there a way to tell the DTMF decoder to require a digit to be held longer before decoding? Thanks!
