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.
