Alex

Initially I did not put dlg_manage(), after reading your post I added the dlg_manage(). Now in route section my code in kamailio.config looks as below.

 

 

        dlg_manage();
        if (is_method("INVITE"))
        {
             if (!has_totag())

             {
                if($DLG_count > 1)
                {
                        sl_send_reply("503","RESOURCE UNAVAILABLE");
                        exit;
                }
                else
                {

                        setflag(FLD_DLG);

                        xlog("Dialog count = $DLG_count\n");
                }
             }

The end result still remains same. The DLG_count still shows as 0 irrespective of number of calls present in system.

 

Can somebody points whats wrong I am doing here.

 

Regards,

Austin

Are you calling dlg_manage() when processing the initial INVITE request?
