Hey Errol,
What I get from Daniel's email is that you only need to add this route in
your script and it will trigger itself automatically when "uac_req_send()"
function is executed.
event_route [tm:local-request] { # Handle locally generated requests
xlog("L_INFO", "Routing locally generated $rm to <$ru> + Modify the
User-Agent Header \n");
user_agent_header="User-Agent: My Super SIP Server" ;
}
Reference:

BR,
Sammy
