[OpenSIPS-Users] loose_route()

[Victor Gamov]

Thanks Bogdan!

Now I have one more rr-question.

ACK request received by opensips listen on X.X.X.X at port 5060

ACK sip:74951000000 at X.X.X.X:5060 SIP/2.0.
Max-Forwards: 10.
Record-Route: <sip:Y.Y.Y.Y;lr=on;ftag=2204003977>
Via: SIP/2.0/UDP Y.Y.Y.Y;branch=z9hG4bK9a79.79e07dd4.2
Via: SIP/2.0/UDP 
Z.Z.Z.Z:50072;rport=50072;branch=z9hG4bKc740505a77ff27fd47aeaded4f9c9287e3e68c732824a333ac632064bb1cc6d7
Call-id: 3749305934 at 192_168_100_114
Cseq: 1 ACK
From: <sip:22222 at domain-1.su>;tag=2204003977
To: <sip:74951000000 at domain-2.ru>;tag=bd829e82ae5c473bdc4d5e71154c80a7
Route: <sip:X.X.X.X;lr=on;ftag=2204003977>
Route: <sip:X.X.X.X:50080;lr=on>
Content-length: 0

loose_route() called and return true.
I expect then topmost Route-header
Route: <sip:194.149.90.8;lr=on;ftag=2204003977>

will be removed, then next (last) Route header will be inspected and 
packet will be forwarded to X.X.X.X port 50080.

But R-URI rewrited to
sip:X.X.X.X:50080;lr=on

and request forwarded to X.X.X.X port 5060

log says:

dp=5060;


Where I'm wrong?
