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::

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?

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.
