[OpenSER-Users] concurrent call limit per user / customer

Hi @ all, I was wondering if anyone of you guys already implemented a system where one could limit the maximum number of concurrent calls? With ISDN-terminaladapters or analog-telefon-adapters it is no problem because the hardware itself is the limiting device, but with the growing amount of IP PBXs the need becomes obvious. I am playing with the thought of writing something myself, but I am more a copy&paste programmer, so it will take quite some time :D Maybe someone here likes the idea? Here are my thoughts of how a module could provide a simple functionality: INVITE: check 200 OK: create Re-INVITE: update BYE: delete must provide: create_call() update_call() delete call() check_limit() create must save uuid,from,to,callid,timestamp in DB, from/to just for human readability ;) update must update timestamp with uuid/callid match ( we enforce 300sec re-invite call refresh ) delete must delete the DB entry with uuid/callid match check must count DB entries with uuid match and return amount of active calls. cheers, Patrick.
