[SR-Users] BYE processing info (was: sip-router listen address)

Hello, How does sip-router process this BYE? BYE sip:321456@<sip-router_ip>:7080 SIP/2.0 Via: SIP/2.0/UDP <remote_uac_ip>:5060;branch=z9hG4bK7fb4c2325A0617FF From: <sip:445566@mydomain.com:5060>;tag=19C8FD8-72B75A25 To: "321456" <sip:321456@<sip-router_ip>:7080>;tag=as28777464 Route: <sip:<sip-router_ip>;lr=on> CSeq: 1 BYE Call-ID: 2b9512ef7ea290f07c54db1808e32211@<asterisk_ip>:7080 Contact: <sip:445566@<remote_uac_ip>:5060> User-Agent: UAc Max-Forwards: 70 Content-Length: 0 Does it routes the BYE, reading first the RURI or the Route header field? What if <sip-router_ip>:7080 is not itself (myself variable), because currently the proxy is listening at different port (5060)? Note: proxy working in stateful mode. Regards, Claudio pd: I've read section "16.4 Route Information Preprocessing" of rfc but it's not clear for me in this case.
