Controlling Your External Call Charges
During any type of communication, your extension systematically
displays the elapsed call time for the current call.
If your current call is an external outgoing call over the public ISDN
network, it also usually displays the cost for the current call.
According to your public telecommunications exchange, the display
of charging or Advice Of Charge (AOC) data may be received during
the course of each call – the AOC_D service – or may be received
cumulatively at the end of each call – the AOC_E service.
Whenever available, the cost of a call is displayed in Euros, as
shown on the following screen:
