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@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 to_tag:: callee_contact:: callee_cseq:: callee_route_set::

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.
