I use different clients with MythPhone. If I configure them to use the
RFC2833 DTMF there is this line :
a=rtpmap:101 telephone-event/8000
during the INVITE.

Anyway, when I'm using a UserAgent who generate this line (example
KPhone without the video stuffs, or a BudgeTone hardphone), MythPhone is
able to receive the DTMF signal, but always impossible to send it even
if MythPhone is the receiver or the caller...

Thanks in advance
