Notes:
The implementation of this specific service assumes that
your facility uses the Least Cost Routing (LCR) method for
external calls. It also assumes that, at the very least, these
outgoing calls are subjected to call detailed records that are
managed within an external charging server. Contact your
system administrator for more information. He/she will also
provide you with the accepted account code format.
As indicated, your extension is equipped with a charge
counter that accrues a cumulative total of the charges for
your outgoing calls. Your system administrator or facility's
attendants have the ability to consult any charge counter. If
necessary, contact them for more details
Your extension may also be subject to call detailed records.
This usually involves your outgoing external calls, however
they may also refer to your internal and incoming calls.
These records save the details for each involved call:
number called, date and time, length, etc. These records
are generally used by your system administrator to monitor
your telephone facility's invoicing. If necessary, contact your
system administrator for more details.
