I am getting problem to register Voxalot in Sipura 3000 . Seems. NAT/firewall problem from my ISP. I tried to use stun server, but no luck. I was reading on site
http://ag-projects.com, recommend to implement/use ICE in sip device. I do not see any place in Sipura 3000 to mention this value. Any idea how to use ICE.
