Hi All, I have a customer who’s switching and they have a ton of Flying Voice IP542N’s. However the phone is not sending the register correctly: It’s sending: From: "225"<sip:@mydomain.com:5060>; instead of From: <sip:225@mydomain.com:5060>; U 70.24.19.57:1025 -> 111.222.333.44:5060 REGISTER sip:mydomain.com:5060 SIP/2.0..From: "225"<sip:@mydomain.com:5060>;tag=112f2a2e..To: <sip:@mydomain.com:5060>..Call-ID: 225ba8c0-13c4- 5805830e-2254-5bb7@192.168.1.830..CSeq: 1 REGISTER..Via: SIP/2.0/UDP 192.168.2.10:1025;branch=z9hG4bK5805830e225e7dada50c;rport..Max-Forwards: 70..Supported: replaces..User-Agent: FLYINGVOICE IP542N SV3. 10 201411190025..Contact: <sip:225@192.168.2.10:1025>..Expires: 120..Allow: ACK,BYE,CANCEL,OPTIONS,INVITE,MESSAGE,NOTIFY,SUBSCRIBE,REFER,INFO,UPDATE..Content-Length: 0.... # U 111.222.333.44:5060 -> 70.24.19.57:1025 SIP/2.0 401 Unauthorized..Via: SIP/2.0/UDP 192.168.2.10:1025;branch=z9hG4bK5805830e225e7dada50c;rport=1025;received=70.24.19.57..From: "225" <sip:@mydomain.com:5060>;tag=112f2a2e..To: <sip:@mydomain.com:5060>;tag=2QNU0767ct9Sr..Call-ID: 225ba8c0-13c4-5805830e-2254-5bb7@192.168.1.830..CSeq: 1 REGISTER..User-Agent: FreeSWITCH..Allow: INVITE, ACK, BYE, CANCEL, OPTION S, MESSAGE, INFO, UPDATE, REGISTER, REFER, NOTIFY, PUBLISH, SUBSCRIBE..Supported: timer, path, replaces..WWW-Authenticate: Digest realm="mydomain.com", nonce="7976b329-0037-4b7e-abf7- 8c35278d58be", algorithm=MD5, qop="auth"..Content-Length: 0.... # U 70.24.19.57:1025 -> 111.222.333.44:5060 REGISTER sip:mydomain.com:5060 SIP/2.0..From: "225"<sip:@mydomain.com:5060>;tag=112f2a2e..To: <sip:@mydomain.com:5060>..Call-ID: 225ba8c0-13c4- 5805830e-2254-5bb7@192.168.1.830..CSeq: 2 REGISTER..Via: SIP/2.0/UDP 192.168.2.10:1025;branch=z9hG4bK5805830e22a15ef6006a;rport..Max-Forwards: 70..Supported: replaces..User-Agent: FLYINGVOICE IP542N SV3. 10 201411190025..Contact: <sip:225@192.168.2.10:1025>..Expires: 120..Authorization: Digest username="225", realm="mydomain.com", nonce="7976b329-0037-4b7e-abf7-8c35278d58be", uri="sip :mydomain.com:5060", response="0df59a3a89b327a29648625daffd3d23", algorithm=MD5..Allow: ACK,BYE,CANCEL,OPTIONS,INVITE,MESSAGE,NOTIFY,SUBSCRIBE,REFER,INFO,UPDATE..Content-Length: 0.... # U 111.222.333.44:5060 -> 70.24.19.57:1025 SIP/2.0 403 Forbidden..Via: SIP/2.0/UDP 192.168.2.10:1025;branch=z9hG4bK5805830e22a15ef6006a;rport=1025;received=70.24.19.57..From: "225" <sip:@mydomain.com:5060>;tag=112f2a2e..To: <s ip:@mydomain.com:5060>;tag=30em22QBa3Zcm..Call-ID: 225ba8c0-13c4-5805830e-2254-5bb7@192.168.1.830..CSeq: 2 REGISTER..User-Agent: FreeSWITCH..Allow: INVITE, ACK, BYE, CANCEL, OPTIONS, MESSAGE, INFO, UPDATE, REGISTER, REFER, NOTIFY, PUBLISH, SUBSCRIBE..Supported: timer, path, replaces..Content-Length: 0.... # Anyone know how to configure these to send the register request correctly?
