[Users] Question about dispatcher module - sr-users

12 Dec 2006


      Hi, I try to configure openser with the dispatcher module like only ponit of contact and load balancer, it is:
        Register
  UAC ---Register--> LB ---Register--> proxy
  UAC <--200 ok----- LB <--200 ok----- proxy
INVITE
  UAC1 ---Invite--> LB ---Invite--> proxy
  UAC2 <--Invite--- LB <--Invite--- proxy
My load balancer works ok, my question is: May I have a problem with the transactions in the load balacer?
In my proxy i use openser, then in my openser.cfg I make  t_relay("IPLoadBalancer:5060")
and the openser.cfg in LB:
if ( !is_method("REGISTER") ){
        record_route();
};
  if (loose_route()) {        
        if (search("Path")) {
                route(1);               
        };
          if (!add_path_received()) {
                sl_send_reply("503", "Internal Path Error");
                exit;
        };
          route(1);
};
  if (!uri==myself) {
        route(1);
}
  if ( !is_method("REGISTER") ){
        if (search("Path")) {
                route(1);
        };
 if (!add_path_received()) {
                sl_send_reply("503", "Internal Path Error");
        };
};
ds_select_domain("2", "0");
t_on_failure("1");
route(1);
  }
route[1] {
        # send it out now; use stateful forwarding as it works reliably
        # even for UDP2TCP
        if (!t_relay()) {
                sl_reply_error();
        };
        exit;
}
Thanks in advance.
