I've got an HT486 on my network which was configured to send DTMF over RTP. _Was_ being the operative word because post my recent upgrade to 1.2, RFC2833 for DTMF just stopped working! Works fine on my GXP2000, but no longer on the HT486. Got it going again by configuring "sip info" mode. Anyone else had this issue with 1.2 or is it just me? Mark.
