Hi Any intermediate proxy other than the outbound proxy can challenge the UA with a 407 Proxy .... Response. The outbound proxy challenges the UA with a 401 message.

Dear folks, I have a question about '407 Proxy Authenticate Response' in RFC3261 below: May a UA(ex.Bob as a receiver) send '407 Proxy Authenticdate' Response as same as a proxy send. Then does the other UA(Alice as a sender) respond reInvite to Bob(as a receiver) as same as the sender send it to the proxy. Moreover, how does Alice judge who sends the response (from whether Proxy or UA )? Does she judge using Route Header? If you know it, please let me know.
