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?

1- open the RTP ports on the remote extension router.
2- check the setting of your audio device for ur softphone (i guess problem lies here).
3- check you headset or whatever hardware you use.

check and inform me i can test it with you if you wish

I would add to mancoeg:

1) those ports are udp 10000-20000

4) edit the file /etc/asterisk/sip_nat.conf as mentio here by Bob:

Also, it is always recomended to go the Elastix download section and grab a copy of Elastix Without Tears.
