Hi Based on bis09, a server (line3644) " ....If the host portion of the "sent-by" differs from the packet source address, the server MUST add a "received" parameter to that Via header field.(the received source ip)...."
Question: under what circumstances will a server received a SIP message having "sent-by" not the sender ip (besides domain name) ? Also, (line 3679) states that a server shall sent a response for UDP to the "received" parameter, and the port of the "sent-by" parameter. Question: Are we assuming that the intermediate host will open a receiving port as the host stated in the "sent-by" parameter ? Who enforce the rule ?
