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 localnet=192.168.1.0/255.255.255.0 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...) <--- Transmitting (NAT) to 12.215.99.135:55048 ---> SIP/2.0 401 Unauthorized Via: SIP/2.0/UDP 12.215.99.135:55048 ;branch=z9hG4bK9420189357AB69A0;received=12.215.99.135;rport=55048 From: "524" <sip:524 at 38.99.6.67>;tag=AC9CBCE4-E9789765 To: <sip:524 at 38.99.6.67>;tag=as37a7918c Call-ID: 2413b651-ccd41ff6-6af5c1f at 12.215.99.135 CSeq: 1 REGISTER Server: Asterisk PBX 11.19.0 Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY, INFO, PUBLISH, MESSAGE Supported: replaces, timer WWW-Authenticate: Digest algorithm=MD5, realm="asterisk", nonce="43fd2381" Content-Length: 0 Thanks, Jerry -------------- next part -------------- An HTML attachment was scrubbed...
