Ok...maybe is better derive this kind of information from the CDR origineted from SIP/DSS-1|ISUP gateways (for the inbound to outbound calls)....IMHO, B2BUA have too issues with scalability, robustness and transparency....do you agree??

if I not yet received the BYE related with the INVITE (same sip_callid), I can suppose with some margin error that this call is still alive....or i really wrong/forgot something?? what I mean, if I polling in real-time the DB, I can fetch the real time stats on ended calls, refused calls, missed-calls and live calls even if I know that SER don't 'retain' the call state but maybe I can 'derive' this call state from accounting/polling from/to DB.....or maybe the risk to not account the BYE message is too high???
No, that does not make sense to me, there would be too many race conditions. The only viable solution, IMHO, is using B2BUA.
