I guess it would be possible, but it is not implemented (not needed here 
in my setup). Maybe you cann add support for this.

Enable Q931 debugging. AOC-D is transmitted using FACILITY messages. 
ACO-E is transmitted as facility IE (information element) in DISCONNECT, 
RELEASE or RELEASE_COMPLETE message.

You may request AOC data during call setup, but usually, if the ISDN 
line is configured to send AOC, this is not needed.
