[Serusers] ACK relaying?

[Igor Diakonov]

I'm new to ser. I'm trying to setup ser to handle registrations, local call's and forward all other call's to PSTN gateway.


I cant get SER to send ACK's recieved from local client to PSTN gate...
What am I doing wrong?

Here's my config file:

loadmodule "/usr/local/lib/ser/modules/mysql.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/textops.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("auth_db", "calculate_ha1", yes)
modparam("auth_db", "password_column", "password")
modparam("rr", "enable_full_lr", 1)

                break;
        };
       if (msg:len >=  max_len ) {
                sl_send_reply("513", "Message too big");
                break;
        };
        if (!method=="REGISTER") record_route();

        # path determined by record-routing
