No.  sip_route_is_strict writes to route->type when it equals route_unknown.

route_loose = 0 because a route is loose when no hops exist, and the field is zero when sip_route's are created (as part of a larger ast_calloc).

route_unknown is used when a hop is inserted to the head of sip_route->list.  Maybe it would be better if I rename route_unknown to route_invalidated, document that strict/loose needs to be rechecked?
