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
callid:: 1356619-3569384775-474862(a)GBSBC-1.mydomain.com
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

I'm trying to limit all subscriber's
active call according to setting
their
simultaneous use setting defined in database.
But having problem when one subscriber's INVITE message goes to
retransmission. When retranmission occures INVITE messages don't
complete
with BYE and subscriber simultaneus use amount
will hung.
My example code block is below.
Does anyone advice me for overcome INVITE retransmissions?
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.
