Hi team.
We have installed a couple of Thirdlane across a couple of sites now. We have good experience with Elasitx and are looking for a different platform. The only issue we have is registration of remote handsets.
We manage routers at both ends.
We have opened the usually ports 5060, 5369 and UDP 10000 to 20000.
We have even allow completed access for a short period of time.
We can get the handset / extension to register but we are not getting voice.
We have also tried both SIP and IAX
Any advice would be great.
Thank you in advance for your time.
Regards.
AC.

possible nat issue, or stateful inspection from the firewall.. using a sip proxy or edgemarc at the customer site is the most sure-fire method of success.
