I think you're partially right, at least for the AOC-E Message. This
message will come as facility message in the Release or Release_complete
probably. I'll try to figure that out.
Still if the Disconnect message results in a hangup, the AOC Info which
is in the Release_complete will be lost.. so what should we do then? my
proposed idea a way of out-of-band data transmission, which could fix
that problem and probably others as well.

Anyway there are ISDN Specs defining Broadcast Facility Messages which
might happen outside of a call time-scale.
