[Serusers] Why Was This INVITE Not Loose_Route()ed ??

[Klaus Darilion]

Hi Paul!

That something I also asked several times and no answer yet. In my 
experience, loose_route() is true if the request URI contains the "lr" 
paramter (message comes from a strict router). Nevertheless, the 
loose_route function will remove its own Route: header.

I solve the troubles by allowing t_relay for all messages with to-tag 
(in-dialog).

regards,
klaus
