[Asterisk-Users] DTMF tones not recognized...

[Carlos Crembil]

Thank you Michael. I've turned inbandDTMF to "no" and now is working.

Regards,
Carlos.

CISCO probably sends DTMF inband. If this is the case then
the inband DTMF detection is done inside ASTERISK (dsp.c)
and not in the H.323 channel driver. I have a rather old
snapshot of ASTERISK source (~2 weeks old) and inband DTMF
detection works fine.

If the CISCO doesn't send DTMF inband then this is a
problem of the H.323 channel driver and I 'll have to
check it.

So, check to see how does you CISCO send DTMF.

Michael.
