Hello, I am using linphone 3.6.1 to register and receive calls behind a NAT. I configured a stun server, and the registration works with a correctly translated contact address. I can also receive calls, but in the OK that the linphone sends as reply to the INVITE there is an incorrect contact header (I removed the server address):
Via: SIP/2.0/UDP xxx.xxx.xxx.xxx;rport=5060;branch=z9hG4bKgS6vZQ3yQrN8N From: "100" <sip:100@xxxxxxxxxx>;tag=yU6UUQ5acee4r To: <sip:[email protected]:5061;line=06cd7f4971c2485>;tag=1462337420 Call-ID: ce71d6fb-8068-1232-25b2-001122639401 CSeq: 62029362 INVITE Contact: <sip:[email protected]:5061> Content-Type: application/sdp User-Agent: Linphone/3.6.1 (eXosip2/4.1.0) Content-Length: 245 The Contact should have been 86.103.233.126:5061, not the address behind the NAT (192.168.178.20). The [email protected] is the default identity. I don't understand why this is used in this context. This OK message is transmitted several times because the ACK is not received and after a while the call is terminated. This is the INVITE: Via: SIP/2.0/UDP xxxxxxxxx;rport;branch=z9hG4bKgS6vZQ3yQrN8N Max-Forwards: 69 From: "100" <sip:100@xxxxxxxxxxxxxx <sip%[email protected]> >;tag=yU6UUQ5acee4r To: <sip:[email protected]:5061;line=06cd7f4971c2485> Call-ID: ce71d6fb-8068-1232-25b2-001122639401 CSeq: 62029362 INVITE Contact: <sip:mod_sofia@xxxxxxxxxxx:5060> User-Agent: FreeSWITCH-mod_sofia/1.4.6-1~64bit Allow: INVITE, ACK, BYE, CANCEL, OPTIONS, MESSAGE, INFO, UPDATE, REGISTER, REFER, NOTIFY, PUBLISH, SUBSCRIBE Supported: timer, path, replaces Allow-Events: talk, hold, conference, presence, as-feature-event, dialog, line-seize, call-info, sla, include-session-description, presence.winfo, message-summary, refer Content-Type: application/sdp Content-Disposition: session Content-Length: 294 X-FS-Support: update_display,send_info Remote-Party-ID: "100" <sip:100@xxxxxxxxxxxx >;party=calling;screen=yes;privacy=off Is this fixed in a newer release or is there a workaround?
