Thanks for the replies Dale, Martin and Manish. I have checked your points about the Contact header, and I think it is correct (see below for the message that gets sent). Interestingly, the RFC says that for 3rd-party registrations the From header shouldn't be equal to the To header... however , it doesn't say what it should be set to (especially as, in my case, my server doesn't really have an AoR that it can use - it is a genuinely disinterested 3rd party). Anyway, here is the message I send:
REGISTER sip:proxy.freecall.net.au SIP/2.0 Via: SIP/2.0/UDP 64.34.163.35:2340;branch=z9hG4bK1261109824 From: <sip:[EMAIL PROTECTED]:5060>;tag=1668684051 To: <sip:[EMAIL PROTECTED]:5060> Call-ID: [EMAIL PROTECTED] CSeq: 1 REGISTER Contact: <sip:[EMAIL PROTECTED]> Max-Forwards: 5 User-Agent: VoXaLot Expires: 3600 Content-Length: 0 where [EMAIL PROTECTED] is my AoR, [EMAIL PROTECTED] is my desired contact, and 64.34.163.35 happens to be my server's IP address. I get back a 200, so as far as I can tell, the freecall registrar is happy with everything. However, if I call the AoR, I just get silence... my 999999 contact never gets contacted. Any other pointers would be much appreciated. Thanks a lot. -- Craig _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
