Hi, I have a few questions. I found if I make a call and the call connects that DTMF and avmd does not work unless I play an audio file. Here are a few settings I am using. session.Execute("start_dtmf_generate", "true"); session.Execute("set", "sleep_eat_digits=true"); session.Execute("set", "suppress-cng=false"); I also found that sometimes when I play an audio file and if I am not talking that even the audio file will not play. If I talk the audio continues to play. Not sure if this is a bug or a settings. I also see that log AVMD using fs_cli.exe get output to the screen only when audio file is playing or me talking. (odd). What I want to do is make a call and hold for DTMF and or beep (AVMD) without having to play audio.
