[Serusers] BD accountingok, but no connection

Hello to all I already have SER going to the DB to check if the endpoints are registered, but when I enabled the DB accountig I couldnt do calls between the endpoints. Can someone check my routing policy and tell me why does SER always returns "Not Found"? Thanks Joao theres my ser.conf: debug=5 #fork=no log_stderror=yes check_via=no # (cmd. line: -v) dns=no # (cmd. line: -r) rev_dns=no # (cmd. line: -R) fifo="/tmp/ser_fifo" # ------------------ module loading ---------------------------------- loadmodule "/usr/local/lib/ser/modules/postgres.so" loadmodule "/usr/local/lib/ser/modules/sl.so" loadmodule "/usr/local/lib/ser/modules/tm.so" loadmodule "/usr/local/lib/ser/modules/rr.so" loadmodule "/usr/local/lib/ser/modules/maxfwd.so" loadmodule "/usr/local/lib/ser/modules/usrloc.so" loadmodule "/usr/local/lib/ser/modules/registrar.so" loadmodule "/usr/local/lib/ser/modules/auth.so" loadmodule "/usr/local/lib/ser/modules/auth_db.so" # ----------------- setting module-specific parameters --------------- modparam("usrloc", "db_mode", 1) modparam("usrloc", "user_column", "username") modparam("usrloc", "contact_column", "contacto") modparam("usrloc", "expires_column", "expires") modparam("usrloc", "db_url", "DB_STUFF") modparam("usrloc", "timer_interval", 120) modparam("auth_db", "calculate_ha1", yes) modparam("auth_db", "user_column", "username") modparam("auth_db", "domain_column", "dominio") modparam("auth_db", "calculate_ha1", 1) modparam("auth_db", "password_column", "password") modparam("auth_db", "use_rpid", 0) modparam("auth_db","db_url","DB_STUFF") modparam("rr", "enable_full_lr", 1) # ------------------------- request routing logic ------------------- route{ if (!mf_process_maxfwd_header("10")) { sl_send_reply("483","Too Many Hops"); break; }; if ( msg:len > max_len ) { sl_send_reply("513", "Message too big"); break; }; if (loose_route()) { t_relay(); break; }; if (uri==myself) { if (method=="REGISTER") { if (!www_authorize("DB_IP", "utilizador")) { www_challenge("DB_IP", "0"); break; }; save("registo_sip"); break; }; if (!lookup("utilizador")) { sl_send_reply("404", "Not Found"); break; }; }; if (!t_relay()) { sl_reply_error(); }; }
