I have a trixbox(2.8) setup and softphone has not problem to register in and function. However the 7940g that I have just can’t get the registration part through. firmeware is SIP 8.11. It loaded the firmware and configuration into the phone. But it always show a little cross besides the phone which means not registered properly. When I call it will just show INV. and I checked the /var/log/asterisk/full log, “No matching peer” messages shows everytime the phone tries to register.
I have struggled for couple days. Can anybody shine some light on it.
