[Serusers] local calls + pstn gateway

Hi, I am making some progress. I still can not call "internal" sip-sip numbers, but now, instead of insisting on forwarding to the gateway, SER 404's. Debug says that the called party is not in usrloc, although I can see the entry in the location table in the db. I have attached my ser.cfg, output from debug, and ngrep in the hope that someone can show me the error of my ways. -------------ser.cfg------------------------------------------ # # $Id: ser.cfg,v 1.21.4.1 2003/11/10 15:35:15 andrei Exp $ # # simple quick-start config script # # ----------- global configuration parameters ------------------------ debug=4 # debug level (cmd line: -dddddddddd) fork=yes log_stderror=no # (cmd line: -E) /* Uncomment these lines to enter debugging mode #debug=7 #fork=no #log_stderror=yes */ check_via=no # (cmd. line: -v) dns=no # (cmd. line: -r) rev_dns=yes # (cmd. line: -R) #port=5060 children=4 fifo="/tmp/ser_fifo" # ------------------ module loading ---------------------------------- loadmodule "/usr/lib/ser/modules/mysql.so" loadmodule "/usr/lib/ser/modules/sl.so" loadmodule "/usr/lib/ser/modules/tm.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/domain.so" loadmodule "/usr/lib/ser/modules/auth.so" loadmodule "/usr/lib/ser/modules/auth_db.so" loadmodule "/usr/lib/ser/modules/acc.so" loadmodule "/usr/lib/ser/modules/exec.so" loadmodule "/usr/lib/ser/modules/group.so" #loadmodule "/usr/lib/ser/modules/msilo.so" #loadmodule "/usr/lib/ser/modules/print.so" #loadmodule "/usr/lib/ser/modules/textops.so" #loadmodule "/usr/lib/ser/modules/jabber.so" loadmodule "/usr/lib/ser/modules/uri.so" #loadmodule "/usr/lib/ser/modules/vm.so" # ----------------- setting module-specific parameters --------------- # -- usrloc params -- #modparam("usrloc", "db_mode", 0) # Uncomment this if you want to use SQL database # for persistent storage and comment the previous line modparam("usrloc", "db_mode", 2) # -- auth params -- # Uncomment if you are using auth module # #modparam("usrloc", "db_url", "sql://ser:<password>@localhost/ser") modparam("usrloc", "db_url", "sql://ser:heslo@wlgcd1:3306/ser") modparam("auth_db", "db_url", "sql://ser:heslo@wlgcd1:3306/ser") modparam("group", "db_url", "sql://ser:heslo@wlgcd1:3306/ser") modparam("uri", "db_url", "sql://ser:heslo@wlgcd1:3306/ser") modparam("domain", "db_url", "sql://ser:heslo@wlgcd1:3306/ser") modparam("auth_db", "calculate_ha1", yes) # # If you set "calculate_ha1" parameter to yes (which true in this config), # uncomment also the following parameter) # modparam("auth_db", "password_column", "password") # -- rr params -- # add value to ;lr param to make some broken UAs happy modparam("rr", "enable_full_lr", 1) # -- acc params -- modparam("acc", "log_level", 1) # that is the flag for which we will account -- don't forget to # set the same one :-) modparam("acc", "log_flag", 2 ) # ------------------------- Domains Covered ------------------------ alias="fx.net.nz" alias="vixen" alias="vixen.fx.net.nz" alias="202.53.189.50" alias="special.fx.net.nz" alias="wlgvx1.fx.net.nz" #alias="202.53.189.23" #alias="202.49.159.10" # ------------------------- request routing logic ------------------- # main routing logic route{ /* ********* ROUTINE CHECKS ********************************** */ # filter too old messages if (!mf_process_maxfwd_header("10")) { log("LOG: Too many hops\n");
