recheck config and saw that I used dlg_manage() most before route(QUOTA)
block. does it sits in the wrong place?you can find my kamailio.cfg file in
attachment also.
# account only INVITEs
* dlg_manage();*
if (is_method("INVITE"))
{
setflag(FLT_ACC); # do accounting
}
###Display Name manipulation###
if (is_method("INVITE") && ($fn != $fU)) {
uac_replace_from("$fU","");
}
### incoming call from SBC###
route(INCOMINGSBC);
###Suspend User###
route(SUSPEND);
### Concurrent Call Limitation Routing Block ###
* route(QUOTA);*

Where do you use dlg_manage()? It is not in the
route you pasted below.
Cheers,

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
