I have 4 Polycom phones behind a firewall. I cannot get them to dial as is says “URL Disabled” so its not registered to my server.
I have tried nat=no, nat=force_rport,comedia still no go.
I have sip.conf set for bindaddr= my server IP.
I have uncommented the localnet188.8.131.52/255.255.255.0 in sip.conf
How do I tell what its NOT liking and which setting to change. I have restarted asterisk each time and or rebooted the phone.
This seems like it is doing the right thing.
(I changed the IP addresses below…)
