Are you sure the RTP isn't going through the Asterisk box?  The reason I
ask is because this sounds suspiciously like the lack of variable-length
DTMF in pre-1.4 Asterisk (did you say what version of Asterisk you are
using and I missed it?).  Of course, depending on the phone, perhaps it
has a similar problem.
