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.

In my mind that statement is completely off the wall, it is not the requesting client that should be responsible for establishing the forwarded call, it never is in the rest of the telecom industry so why should it be the case for SIP?
302 is not about "forwarded call". it just tells the caller that the callee is at some other uri, which the caller may or may not wish to contact. in many pstn networks, you can hear an announcement that the number you tried is not in use and you should try another number instead.
if callee wants to "forward" calls, he has other means for that purpose, for example, his phone can forward the invite to some other uri or he may configure his proxy to do so.
