What about doing the accounting in a B2BUA (just SIP signalling, no media)?
At least a B2BUA is fully dialog stateful (it really knows about CSeq values
and so).

Annoying?
it is only if you try to do accounting in the proxy. if you do
accounting in the gateway, the call continues, but is not free.
lots of effort has gone to implement reliable accounting of sip calls in
the proxy. i personally don't think that it is a good idea, because it
greatly complicates proxy implementation and may force proxying of media
even if it would not otherwise be needed.
