I have set up Elastix and extensions work great within local LAN.

But as soon I try to connect (With X-Lite) from a remote location, there is no sound. It does login to extension without a problem "Ready". It can also make and accept calls, but no sound.I forwarded ports on my router like Elastics Without Tears says:

IAX Port: 4569 (UDP)
Sip ports: 5004 - 5082 (UDP and TCP)
RTP ports: 10000

For sip ports you only need udp not tcp I think. Sound uses the rtp. Do you have the rtp ports limited in the client?

Thank you for reply Don.

Though I manage to get Zoiper IAX softphone working but still no luck with SIP (X-Lite)

Do you have the rtp ports limited in the client?
No I don't. I'm not home at the moment, but think you nailed it, because TCPDUMP shows activity on other ports than 10000-10500. I have X-lite software phone and I don't see any option to set RTP port limit.

Thank you for your help.

Hi there

If you have no problem or security issues, you should open in your router a range of ports from 4000 to 30000 in UDP forwarded to the local IP of the elastix server. If you use less ports, you will have sound problems in SIP.
Otherwise use IAX (not available for xlite softphone).

Waiting for your comments

You need to setup your /etc/asterisk/sip_nat.conf

Have a bit of a search around the forums here for "sip_nat.conf" for the solution :)
