(Answer) (Category) SIP FAQ : (Category) SIP Protocol Operation :
Should responses be sent to the host specified in Via? Is From ever used for sending responses?
The rules for forwarding responses are explained in section 6.47.5 of 2543bis.

Note that if you are a UAS, you are the entity responsible for adding "received" parameter to the top Via so you may want to interpret the last two rules in the section as requiring to send the response to the source address of the request.
