Hi all,

I need to receive some DTMF tones by the users dialing in 1 of my DIDs. The
ITSP forwards the line directly to me without tampering it, so I need to
use the "inband" dtmf mode. The issue is that the system seems to catch the
DTMF tones only when there's an audio (IVR) playback on the channel, once
the audio (IVR) stops so does the DTMF flow. What could be the possible
solution?!
