[Serusers] Filtering redirections

Hi, I would like to deny all 3xx messages coming from subscribers. I found following code in seusers mailing list but my ser give me: "unknown command, missing loadmodule? ". What is wrong? failure_route[1] { if (t_check_status("3[0-9][0-9]")) { t_reply("400","No redirect available"); break; } } I have following modules loaded: loadmodule "/usr/lib/ser/modules/textops.so" loadmodule "/usr/lib/ser/modules/sl.so" loadmodule "/usr/lib/ser/modules/tm.so" loadmodule "/usr/lib/ser/modules/acc.so" loadmodule "/usr/lib/ser/modules/rr.so" loadmodule "/usr/lib/ser/modules/maxfwd.so" loadmodule "/usr/lib/ser/modules/usrloc.so" loadmodule "/usr/lib/ser/modules/registrar.so" loadmodule "/usr/lib/ser/modules/auth.so" loadmodule "/usr/lib/ser/modules/auth_radius.so" SER version 0.8.12 Regards, MC
