Re: [Kamailio-Users] Accounting: How to avoid a fraudulent BYE with lower CSeq?

Yes, but it doesn't explain how to do the accounting when receiving the 200 OK for the BYE.

Uh, well... register a new failure route and don't set the flag for automatic accounting when receiving the BYE, and in your failure route, do something like

if($T_reply_code == 200 || $T_reply_code == 481) # or whatever you want to account { acc_db_request("something", "acc"); }

Or am I missing something?

Well, failure_route will not be called when receiving a 200 OK in this BYE transaction. failure_route is only invoked for [3456]XX responses. 200 can only be handled in on_reply_route, but I don't know if acc flag can be set in on_reply_route.
