[Freeswitch-users] Freetdm DTMF

[curriegrad2004]

and crap, since I wasn't even reading anything here, on the subsequent
transfers from your FXO card, enable the in-band DTMF detector that FS
has. The details on the in-band DTMF detector is here:

But use this with caution, if there is a DTMF detector on the FXO card
itself, make sure you disable it before using it.
