4. simple quick-start config script

 

1. ———– global configuration parameters ————————

 

1. debug=3 # debug level (cmd line: -dddddddddd)
2. fork=yes
3. 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=no # (cmd. line: -R)

1. port=5060

1. —————— module loading ———————————-

 

1. Uncomment this if you want to use SQL database

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”

1. Uncomment this if you want digest authentication
2. mysql.so must be loaded !

loadmodule “/usr/local/lib/ser/modules/auth.so”
loadmodule “/usr/local/lib/ser/modules/auth_db.so”

1. —————– setting module-specific parameters —————

 

1. — usrloc params —

#modparam(“usrloc”, “db_mode”, 0)

1. Uncomment this if you want to use SQL database
2. for persistent storage and comment the previous line

modparam(“usrloc”, “db_mode”, 2)

1. — auth params —
2. Uncomment if you are using auth module

modparam(“auth_db”, “calculate_ha1”, yes)

2. If you set “calculate_ha1” parameter to yes (which true in this config),
3. uncomment also the following parameter)

modparam(“auth_db”, “password_column”, “password”)

1. — rr params —
2. add value to ;lr param to make some broken UAs happy

modparam(“rr”, “enable_full_lr”, 1)

See Below.

1. SQL settings

modparam(“usrloc”, “db_url”,”sql://username:[email protected]/ser”)
modparam(“auth_db”, “db_url”,”sql://username:[email protected]/ser”)

1. ————————- request routing logic ——————-

 

1. main routing logic

route{

1. initial sanity checks — messages with
2. max_forwards==0, or excessively long requests

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;
};

1. we record-route all messages — to make sure that
2. subsequent messages will go through our proxy; that’s
3. particularly good if upstream and downstream entities
4. use different transport protocol

record_route();

1. loose-route processing

if (loose_route()) {
t_relay();
break;
};

1. if the request is for other domain use UsrLoc
2. (in case, it does not work, use the following command
3. with proper names and addresses in it)

if (uri==myself) {

if (method==”REGISTER”) {

1. Uncomment this if you want to use digest authentication

if (!www_authorize(“proxy.example.org”, “subscriber”)) {
www_challenge(“proxy.example.org”, “0”);
break;
};

save(“location”);
break;
};

lookup(“aliases”);

1. native SIP destinations are handled using our USRLOC DB

if (!lookup(“location”)) {
sl_send_reply(“404”, “Not Found”);
break;
};
};

1. forward to current uri now; use stateful forwarding; that
2. works reliably even if we forward from TCP to UDP

if (!t_relay()) {
sl_reply_error();
};

}
