[Freeswitch-users] Freetdm DTMF

[Shane Harrison]

Thanks.  I am currently using bind_meta_app (set to both legs) already
rather than bind_digits.  I'll give bind_digits a shot and see if it
behaves differently.

Note that I do detect the initial *3 digits and because bind_meta_app is
both legs, this is successful no matter which direction the call is setup
from.  However once the dialplan moves to the extension the *3 is bound to,
digits are no longer received.

The worrying thing for me is that ftdm_io.c doesn't even write to the log
that it has received them (nor freetdm above that of course which is
understandable) and I am surprised that the read() influences that since it
works prior on the *3 digits.

Cheers
Shane
