Hello, I am trying to get a new freeswitch installation working and I have it registering to a sip provider just fine and can receive inbound calls but when I try and place a call out through the gateway the switch is rejecting it due to the domain in the to of the INVITE. Here is the INVITE 15:15:19.467351 IP (tos 0x0, ttl 64, id 40045, offset 0, flags [none], proto: UDP (17), length: 1398) 207.4.223.35.5080 > 207.16.137.36.sip: SIP, length: 1370 INVITE sip:16173800299@207.16.137.36 SIP/2.0 Via: SIP/2.0/UDP 207.4.223.35:5080;rport;branch=z9hG4bKcc3a14Zcg8NZp Max-Forwards: 69 From: "FreeSWITCH" <sip: 6172384723@172.16.12.100;transport=udp>;tag=54FXray2SNaKN To: <sip:18023800299@207.16.137.36> Call-ID: 6956c6eb-b6a7-122c-5fb1-725bd701687a CSeq: 114786724 INVITE Here is the REGISTER for the same gateway 15:24:27.746984 IP (tos 0x0, ttl 64, id 40075, offset 0, flags [none], proto: UDP (17), length: 661) 207.4.223.35.5080 > 207.16.137.36.sip: SIP, length: 633 REGISTER sip:207.16.137.36;transport=udp SIP/2.0 Via: SIP/2.0/UDP 207.4.223.35:5080;rport;branch=z9hG4bK9H0SmN8jvavXp Max-Forwards: 70 From: <sip: 6172384723@172.16.12.100;transport=udp>;tag=3jXBNmvUZ3XDe To: <sip: 6172384723@172.16.12.100;transport=udp> Here is my gateway config <gateway name="voip1"> <param name="username" value="6172384723" /> <param name="password" value="testme" /> <param name="realm" value="172.16.12.100" /> <param name="proxy" value="207.16.137.36"/> <param name="register-proxy" value="207.16.137.36"/> <param name="register" value="true" /> <param name="stun-enabled" value="false"/> <param name="from-domain" value="172.16.12.100"/> <param name="aggressive-nat-detection" value="false"/> </gateway> Here is the bridge from the dialplan <action application="bridge" data="sofia/gateway/voip1/1$1"/> I'm currently running FreeSWITCH Version 1.0.trunk (13226M). I hunted around trying to find another option in for the gateway config that would set the to domain to the realm and still send the packet to proxy but could not find one. Any help/hints are welcome. Thanks, -Dale
