Hello list, Hope you are all doing fine! I have stumbled over some piece of dialplan code in which apparently they were trying to avoid recording the DTMF tones in the wav file. It is really messy and I am not sure if this really works. So after a bit of research I found this comment ( https://community.asterisk.org/t/asterisk-dtmf-record/65040) in which it is said:
*"Asterisk strips the DTMF from the audio stream when configured for inband, so internal stuff can react to the DTMF and so the other side does not hear the tone unless they are using inband (in which case it is regenerated)"* So my questions are, what are the cases in which Asterisk regenerates the DTMFs? Does it cause the recording to have the tone as well, or is it only transmitted to the other leg without being generated to the recording file? Also, what if one or both legs are RFC2833? From my tests the RFC2833 events never show up in the recording, but I just want to confirm that this is always true.
