Re: [SR-Users] How to limit number of calls in Kamailio proxy

Hi All Still I am struggling to find a solution how to control the number of calls.

I have few more doubts regarding this.

1. Do I need to enable mysql , so that these counters such as $DLG_count will be updated properly. Now I am getting 0 always irrespective of number of calls in system.

2. For testing purpose, I wanted to set max calls at any point of time should not be more than 1. So I had the check as below

*if($DLG_count > 1) *

I read in some previous posts where someone was mentioning the check as

*if ( avp_check("$DLG_count", "gt/i:10") ) * Please let me know which one is correct.

3. How do I debug whats going wrong. Why $DBG_count is not updated.

Thanks in advance.

Regards, Austin

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.

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

This is continuation with limiting number of calls per Kamailio proxy

server.

...

I modified kamailio.cfg as below.

1. loadmodule "dialog.so"
2. modparam("dialog", "enable_stats", 1)
3. modparam("dialog", "dlg_flag", 4)

Next, as dialog module I can use either active_dialogs() or $DLG_count

to find number of calls present at any given point of time.

...

However if I use active_dialogs() I get parse error when I run kamailio

proxy.

...

Next I used $DLG_count , but always I am getting value of $DLG_count as

...

In route section, I added code as below.

    if (is_method("INVITE"))
    {
            if($DLG_count > 1)
            {
                    sl_send_reply("503","RESOURCE UNAVAILABLE");
                    exit;
            }
            else
            {
                    xlog("Dialog count = $DLG_count\n");
            }
    }

Everytime a new call starts , it prints $DLG_count as 0.

Kindly let me know whats going wrong here.
