Since the release of Free PBX 2.5, has anything changed as far as settings for remote SIP extensions ?
I built a new system yesterday using Trixbox and upgraded to the latest FreePBX 2.5… very funky…
All my internal extensions work no problem but I configured an external SIP extension today and just can not get it to register.
I have built somewhere in my 20’s or Trixbox systems majority of which have external SIP extensions. We manage all the firewalls ( WatchGuard ) for customers and create seperate custom rules for both 5060 and 10000 - 20000 ports NATing to the internal IP address of the Trixbox.
I have re-checked the How To @ http://www.freepbx.org/support/documentation/howtos/howto-setup-a-remote-sip-extension to see if anything has changed but it dosn’t look like it has.
Anyone have any idea’s, i am sure my config is correct, i have also tried setting up an X-Lite softphone from another office with a site to site VPN ( i.e. all ports open ) and although that does register I am only getting one way voice ( from the LAN with the trixbox )
I can also confirm that my sip_nat.conf file has also been setup with the correct IP addresses.
