[Frank Sautter]

hello christian,

many thanks for your excellent description of the problem and your 
design proposal!

looks good for me, even though it would me more elegant to have this 
done by the normal bridge, but as a change in the bridge would have an 
much bigger impact on all channel drivers, i think your proposed 
solution solves the AOC problem with less hassle.

as far as i know AOC is sent with the disconnect or the release message.

i would separate PCT from AOC processing (config files and source code) 
to be more flexible with the AOC part, as there are many possible ways 
AOC could work:
* simple generation of CDR, no forwarding
* pass through of AOC to the other leg
* computations on the incoming AOC (y = a*x + b)
* own AOC computations based on time and destination
* source based AOC computations

these are just some thoughts on what should be possible with AOC in 
asterisk. i know this can not be implemented in the first shot, just to 
keep this in mind when designing the software.
