Hi all, I setup two * boxes with two sip phones (one to each * box). I can make calls from one sip phone to the other via IAX both ways. However, the dtmf tones are just oneway. I use rfc2833 for dtmfmode in the sip.conf on both * boxes, and gsm for IAX. What do I need to achieve twoway dtmf tone pass through? Thnx for your comments.
