[Users] strict to loose - Route Header not removed

[Bogdan-Andrei Iancu]

HI Walter,

I see here three problems:

1) as I guess your proxy IP is 111.222.333.132, I find rather strange 
why the ACK RURI does not contain the "lr" parameter - OpenSER does only 
loose routing and inserts the RR hdr with "lr" and "ftag" params all the 
time. Can you check this in the INVITE and 200 OK? It might be a bug in 
the phone also.

2) even if the proxy does recognize the 111.222.333.132 IP as its own 
(as it follows the "after_strict" processing), not sure why you get this 
"check_self: host != me". Is the output log continuous?

3) indeed there was a bug in RR "after_strict" processing. I fixed it, 
but I cannot commit it since thanks no SF none of the repository is 
online (CVS or SVN) :(.

If yo need it fast, I can generate a patch for you to be able to test.

Thanks and regards,
Bogdan
