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.
