[OpenSER-Users] Dialog module

[David Villasmil]

Hello List,

     I have a simple load balancer with dispatcher. I'm using the DIALOG
module, it is supposed to store in db all info about ongoing dialogs. But my
setup must be wrong, because a lot of dialogs are not removed when the call
is hung up.

Here's my cfg:

#
# simple quick-start config script
# Please refer to the Core CookBook at
http://www.openser.org/dokuwiki/doku.php
# for a explanation of possible statements, functions and parameters.

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");
        exit;
    };

    if (msg:len >=  2048 ) {
        sl_send_reply("513", "Message too big");
        exit;
    };

     if (!method=="REGISTER")
          record_route();

     if (method=="INVITE") { setflag(4); }

    if ( method=="INVITE" || method=="ACK" || method=="BYE" ||
method=="OPTIONS" || method=="CANCEL" ) {
          ds_select_dst("1","2");
          t_on_failure("1");
          t_relay();
          exit;
     };

}

failure_route[1] {

         if (t_check_status("408")) {
                 xlog("L_INFO","Marking GW as failed...\n");
                 ds_mark_dst("p");
                 ds_next_dst();
                 t_on_failure("1");
                 t_relay();
         } else{
                 t_reply("501","Not Implemented");
         }
}


As far as I know, using the record_route assures that all messages are
passed through the proxy so that dialogs must be removed... but they'r not



Any ideas?


Thanks a lot.
