you can't configure call transfer at the proxy! call transfer is a feature of the user agent!

ask google for "SIP REFER call transfer".

hi,

I have downloaded SER from the website Iptel.org. I was able to run the server in authentication mode. I want to call transfer option to be enabled. In order to do that which module has to be added to the configuration file.

The configuration file is as shown.

# # $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=3 # 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=no # (cmd. line: -R) #port=5060 #children=4 fifo="/tmp/ser_fifo" alias=serproxy.com

# ------------------ module loading ----------------------------------

# Uncomment this if you want to use SQL database 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"

# Uncomment this if you want digest authentication # mysql.so must be loaded ! loadmodule "/usr/lib/ser/modules/auth.so" loadmodule "/usr/lib/ser/modules/auth_db.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)

modparam("usrloc", "db_url", "sql://ser:heslo@localhost/ser")

# -- auth params -- # Uncomment if you are using auth module # 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)

# ------------------------- request routing logic -------------------

# main routing logic

route{

   # initial sanity checks -- messages with
   # 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;
   };

   # we record-route all messages -- to make sure that
   # subsequent messages will go through our proxy; that's
   # particularly good if upstream and downstream entities
   # use different transport protocol
   record_route();
   # loose-route processing
   if (loose_route()) {
           t_relay();
           break;
   };

   # if the request is for other domain use UsrLoc
   # (in case, it does not work, use the following command
   # with proper names and addresses in it)
   if (uri==myself) {

           if (method=="REGISTER") {

# Uncomment this if you want to use digest authentication if (!www_authorize("serproxy.com", "subscriber")) { www_challenge("serproxy.com", "0"); break; }; save("location"); break; }; if (!proxy_authorize("serproxy.com", "subscriber")) { proxy_challenge("serproxy.com", "1"); break; };

           # native SIP destinations are handled using our USRLOC DB
           if (!lookup("location")) {
                   sl_send_reply("404", "Not Found");
                   break;
           };
   };
   # forward to current uri now; use stateful forwarding; that
   # works reliably even if we forward from TCP to UDP
   if (!t_relay()) {
           sl_reply_error();
   };

}

Can you please send which module has to be added.

Thanks

Sudheendra
