Hi, I tried again getting DTMF detection on my ISDN devices with dahdi going again. I used the channel debug to see whether asterisk sees the frames and detects them as DTMF.
Interestingly here's what works: 1. GSM phone -> chan_dahdi g1 -> asterisk -> can_sip -> SIP phone Both the GSM phone and the SIP phone can issue DTMF that will be detected as features (transfer) 2. GSM phone -> chan_dahdi g1 -> asterisk -> chan_dahdi g4 -> ISDN phone The GSM phone can issue DTMF that will be detected. The ISDN phone won't. (That's my issue.) I don't see any messages of asterisk recognizing the DTMF frames when pressing the keys. I do hear the DMTF sound on both phones. 3. ISDN phone -> chan_dahdi g4 -> asterisk -> chan_dahdi g1 -> GSM phone The ISDN phone can issue DTMF that will be recognized and so does the GSM phone. So. When the ISDN phone is receiving a call on g4 its DTMF sounds won't be recognized. OTOH when the GSM phone on g1 is being called it's sounds are recognized. Sounds like a configuration issue to me. Does anybody have an idea what to look out for?
