The core functionality provided by the dispatcher module is simplify to 
modify the request URI ($ru) (ds_select_domain()) or the destination set 
($du) (ds_select_dst()).

Thus, after running the operation, you would append the Contact yourself:

    ds_select_domain("1", "4");
    append_to_reply("Contact: <$ru>\r\n");
    sl_send_reply("300", "Redirect");
