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.

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.
