[Serusers] Handling 302 responses

[Roger Lewau]

Hello Juha and Andrey

302 "Moved temporarily" is definately about forwarding/redirecting calls. 
This is how the vast majority of all IP phones and ATAs handle call 
forwarding. It might not be the intended use of 302 according to RFCs, even 
if I see nothing that says otherwise, but this is how it is used in end 
devices today. This brings us back to my original question. How do you guys 
handle 302 redirection so that costs are charged to the callee.

Kind regards
Roger

You can also use 302 responses to gather some information about the
remote party. Contacts returned in the response are not necessarily
the SIP URI's. I've tried using mail addresses, SIP tel: URI's and
HTTP URLs too.

So, if the remote party is Busy at the moment, but has other ways to
let u contact them, 302 is one of the answers to this.
