I have been experiencing issues regarding ‘talk-off’ & dtmf signal detection.
Is there a way in the dialplan to temporarily turn off all dtmf signal detection (& likewise dtmf signal re-generation) for a channel?
For instance, I have recorded music that plays back via IVR. The music has a ‘telephone-themed’ composition, which includes some processed DTMF tones (actually recorded into the sound files). So when Asterisk plays through the music and hits those tones, it tries to re-generate them as new DTMF tones that scramble the music.
I have tried setting my dtmfmode to both rfc2833, and in-band, with the same result. In both cases, I had enabled only ulaw & alaw.
Thank you in advance for any suggestions.
