Thanks for quick response Daniel,

My kamailio version is 3.2.3 (x86_64/linux) .
I want to use dlg_manage() before but not sure which side of my call limitation route code block.
can you advise me where to use dlg_manage() in my routing?
here is my route block defined below;


route[QUOTA] {

        if (is_method("INVITE") && $fU == $avp(s:username)) {

        avp_db_query("select quota from subscriber where username='$avp(s:username)'", "$avp(s:quota)");

        $var(SIZE) = 0;
        get_profile_size("callquota", "$avp(s:username)", "$var(SIZE)");
                xlog("L_INFO", "CALL_KAMAILIO:Call originated from = $fd\n");
                xlog("L_INFO", "Active call amount for $fU is $var(SIZE) , call-id=$ci, quota=$avp(s:quota)\n");
        if( $var(SIZE) >= $avp(s:quota) ){
               sl_send_reply("403", "Simultaneous calls limit reached");
               xlog("L_INFO", "QUOTA:Limit of $var(SIZE) active calls has been reached for user=$avp(s:username), call-id=$ci, quota=$avp(s:quota)\n");
               exit;
        }
        set_dlg_profile("callquota","$avp(s:username)");
        }
}

Hello,

what version of kamailio are you using?

State 1 is for dialogs that were not relayed (or they haven't received any reply yet). That means you create the dialog and don't relay the INVITE. Try to us dlg_manage() just before relaying the INVITE.

Cheers,
Daniel

Hi,

is there any advise about my problem?
I'm using kamailio in my production environment and this issue started to reproduce a lot.
is there any way to discard retransmitted INVITE messages from counting dialog?

thanks for the response Daniel,

has_totag not solved my problem.

in a deep search I realized that these retransmission INVITE dialogs are waiting in dialog list as state = 1. one example is below;
is there any way to clear these dialog which state is waiting for state = 1 or any other solution is welcome for me?

dialog::  hash=246:499719317
        state:: 1
        ref_count:: 1
        timestart:: 0
        timeout:: 0
        from_uri:: sip:02165151057@xxx.xxx.xxx.xxx
        from_tag:: 3569384775-474868
        caller_contact:: sip:02165151057@xxx.xxx.xxx.xxx:5060
        caller_cseq:: 2
        caller_route_set:: 
        caller_bind_addr:: udp:xxx.xxx.xxx.xxx:5060
        callee_bind_addr:: 
        to_uri:: sip:4115667@xxx.xxx.xxx.xxx
        to_tag:: 
        callee_contact:: 
        callee_cseq:: 
        callee_route_set::

I haven't implemented it myself yet, but all examples I've seen check for
!has_totag() in the INVITE when doing call limit accounting. So
if (is_method("INVITE") && $fU == $avp(s:username) && !has_totag())
in your case. But that only works if the device received the initial 100
Trying with a tag from Kamailio.

But might it not be better to just do the count in the INVITE and
adding/deleting of dialogs in the dialog event routes?
http://kamailio.org/docs/modules/stable/modules_k/dialog.html#id2556156
Problem here is that if the limit is 5 and and there are more than 5
concurrent INVITES you'd have to drop calls with a 200 OK response.
