DTMF Tx Method               Select the method to transmit DTMF
signals to the far end:
                                           InBand, AVT, INFO, Auto,
InBand+INFO, or AVT+INFO.
                                           InBand sends DTMF using the
audio path. AVT sends
                                           DTMF as eypents. INFO uses
the SIP INFO method. Auto
                                           uses InBand or AVT based on
the outcome of codec negotiation.
                                           The default is Auto.

I was reading this manual when I saw your post. You should check it
out if you haven't already.
