It may be a version thing; they've been patching the stuffing out of DTMF on the GSX.

Anyone out there know the magic incantation on SONUS boxes to make
RFC2833 DTMF signaling work consistently? We've got one vendor using
SONUS with this turned on that works flawlessly. For the rest we've had
to fall back to in-band DTMF. Far as I can tell, they're all GSX;es.

Thanks in advance,
