Why do you need B2BUA for billing in the first place? I use SER acc based billing (that is: registering INVITE and first BYE received and then analyzing this with external application). I do it on production system.
I was also concerned about reliability of such solution. But as I'm now sure all my remote gateways will always send BYE at the end of call, no matter what happened, I don't see any problem. Even if somebody cuts power/RTP/whatever at UA.
I used to have 1 or 2 unregistered calls per month, now I have none. Everything is billed...
