[Serusers] routing between ser and asterisk

hi there, i have a question about routing between SER and asterisk: I run SER and * on the same machine, so i configured * to listen on port 5070 (sip.conf: bindport 5070). Now i want to route all numbers that are not found in SER to *, therefore i wrote to ser.cfg in the main route section: if (!lookup("location")) { #sl_send_reply("404", "nicht gefunden"); rewritehostport("192.168.2.183:5070"); route(1); break; }; route(1) is the following: route[1] { # ----------------------------------------------------------------- # Default Message Handler # ----------------------------------------------------------------- if (!t_relay()) { sl_reply_error(); }; } i have two SER-users: 1000 and 1001 i have one * user: 1002 when i dial 1002 i get immediately 'User not found' does anyone have a hint?
