Iñaki, Alex,
thanks. But I'm still confused about this.
The above is what I believe I'm doing in my tests: I am setting the
RURI to the real location of the registered user and I'm passing the
URI of opensips in the sole Route header.

How my cfg should accomplish this then? If loose_route returned TRUE,
I would simply relay the request to the address in the RURI.
Do you mean I should not be using loose_route() for this? Should I
perform the checking in another way?
Well, of course I could come up with something else, but it seems to
me loose_route() would be the simplest way to do it if there was not
that exception clause that I really don't understand why is there.
