[OpenSIPS-Users] INVITE not forwarded, call fails

[Jeff Pyle]

Yes.  Trying adding this to the reply route:

        if (client_nat_test("1")) {
                fix_contact();
        }

For reasons I can't remember, the only test that works for the reply route
is "1", so you shouldn't change it.

Make sure you arm the reply route with t_on_reply() before t_relay.
