i have _partially_ implemented AOC into the libpri and chan_zap part of 
asterisk (the IEs for AOC units are decoded and encoded and you will see 
the AOC info on the console if you have increased verbosity to 5).

unfortunately it was beyond my scope to propagate this information to 
the bridged channel, as the info from the telco provider is transmitted 
during the call termination phase and asterisk destroys the bridge to 
early (right after it receives the first notice that the call has to be 
terminated) and so there is no possibility to pass the AOC to the 
bridged channel nor to write anything to the CDR.

what has to be done is to rewrite the call termination process so it 
does not terminate each of it's bridged legs seperately in a state 
machine but together.
