I hope that loose_route() will process Route headers not RURI.
RFC-3261 16.4 says that
"The proxy MUST inspect the Request-URI of the request. If the
Request-URI of the request contains a value this proxy previously
placed into a Record-Route header field (see Section 16.6 item 4),
the proxy MUST replace the Request-URI in the request with the last
value from the Route header field, and remove that value from the
Route header field. The proxy MUST then proceed as if it received
this modified request."
So loose_route() inspect R-URI. But R-URI
sip:74951000...@x.x.x.x:5060
is not the same as inserted into Route
(sip:X.X.X.X;lr=on;ftag=2204003977).
A RR hdr cannot be completely copied to a RR, as syntactically speaking
they are different . RR is a name-addr spec, while RURI is a SIP
URI...what you see there as lr and ftag are RR hdr param, so cannot be
copied into RURI - just the URI part of RR is copied into RURI.
So Route header
Route: <sip:X.X.X.X;lr=on;ftag=2204003977>
removed, R-URI untouched, next Route processed and $du is
sip:X.X.X.X:50080 now.
not really :
1) opensips finds its IP in RURI -> previous hop was a strict router
2) next hop is in the first Route hdr
3) next hop has "lr" param, so next hop is a loose router -> strict
to loose conversion
A) last Route is moved into RURI (end point address)
B) send (via $du) the call to next hop (from top most Route).

As my script does not decide to call lookup() but t_relay(), then
request forwarded to $du.
This was my (incorrect) logic...
