The setup goes modem to router then to the phone. The phone registers fine. The works fine but only when called. When you place a call on the remote extension it rings the phone, but when you answer there is no audio either way. I have tried setting the phone into the DMZ and I have also tried forwarding the ports and I still get the same thing happening. I do not know what can cause the remote extension to work fine when called but fail when it makes the call. Anyone out there have a new idea for me to try?
