A sip phone using the SIP protocol never sends actual DTMF when
dialing, instead it uses an invite message to asterisk, which has the
digits dialed in it. The tones you hear -when pushing the buttons on
your phone- are actualy not sent to asterisk until you either press
dial or #, or if your dialplan setup in diaplan.xml sends it. The
inband and outband settings are only used when already talking on the
phone (I might be wrong on this one, anybody out there if I am, please
let me know).

 What does the phones display tell you when you dial?
