Hi Brian, Ok here's the sip trace captured at the softswitch. BTW, I noticed that during startup, I see FS printing out this message: 2010-01-29 01:30:05.634220 [NOTICE] sofia_reg.c:2267 Added gateway 'Test-Inbound' to profile 'external' 2010-01-29 01:30:05.634547 [ERR] sofia.c:1663 ERROR: username param is REQUIRED! 2010-01-29 01:30:05.634657 [ERR] sofia.c:1663 ERROR: username param is REQUIRED! Which is weird, because as you can see from the config, the username is infact present. Weird! Anyway, here's the trace REGISTER sip:myswitch.net.au SIP/2.0 Via: SIP/2.0/UDP 173.xxx.xxx.xxx:5080;rport;branch=z9hG4bK1U32gpr9vj5eF Max-Forwards: 70 From: <sip:user1@myswitch.net.au;transport=udp>;tag=11Qey4tcrUH9g To: <sip:user1@myswitch.net.au;transport=udp> Call-ID: cd589b73-031e-445f-a4d8-2fe334d81bbc CSeq: 126255215 REGISTER Contact: <sip:gw+Test-Inbound@173.xxx.xxx.xxx:5080;transport=udp;gw=Test-Inbound> Expires: 60 User-Agent: FreeSWITCH-mod_sofia/1.0.trunk-15980 Allow: INVITE, ACK, BYE, CANCEL, OPTIONS, MESSAGE, UPDATE, INFO, REGISTER, REFER, NOTIFY Supported: timer, precondition, path, replaces Content-Length: 0 SIP/2.0 409 Conflict Via: SIP/2.0/UDP 173.xxx.xxx.xxx:5080;rport;branch=z9hG4bK1U32gpr9vj5eF From: <sip:user1@10.1.3.20;transport=udp>;tag=11Qey4tcrUH9g To: <sip:user1@10.1.3.20;transport=udp> Call-ID: cd589b73-031e-445f-a4d8-2fe334d81bbc CSeq: 126255215 REGISTER Content-Length: 0 .and then this message just repeats again and again with every REGISTER request.
