$du is the outbound proxy address, it doesn't change R-URI or some other
value inside the SIP message, is just internal to kamailio.
Most of those functions like t_relay_to_tcp(), ..., were developed
before having the variables, after that a lot of them can be replaced
with setting variables and just relaying.
