Hi, I'm having a theorical question/problem about the correct sip behavior in some scenario and i can't find anyone who tell me what is the right thing to do (Honestly I read the RFC, but it doesn't help or i don;t have the complete picture on my head). I found some sip clients do one thing and other work different, so i don't known what to do...
the scenario is basically like this: UAC <-----> SIP PROXY <-------> UAS - uac send an invite to proxy (the invite is for some client of the remote UAS) - it forwards it to UAS (based on static routing definition or domain info or SRV) - later uas sends a 407 response (proxy auth or www auth), with UAS ip in the Contact header field - the proxy receives this and forward it to UAC (without changeing the Contact field) - here are two behaviors depending the client: a) the UAC send a new invite , with the digest auth, to the proxy b) the UAC send a new invite , with the digest auth, direct to the UAS. the question is which is the correct behavior? a or b? thanks in advance Mauro _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
