[OpenSIPS-Users] LOOSE Route and NAT not being fixed

[Mike O'Connor]

Hi All

I seem to have broken my loose routing for NAT'd users, but I can not
see what I have wrong.

Any ideas what I might have wrong ?

Thanks as always.
Mike

    # take the path determined by record-routing

        # re-INVITEs alos, as some buggy clients do change route set
