Making Outside (External) Calls
Calling Outside Lines—an Overview
Outside calls are made via central office (C.O.) lines. To call an outside number
you first need to press a programmed line button or line group button or dial the
C.O. line access code (‘9’ for example). If you have an LCR button (for least cost
routing) you should press that. Ask your system administrator what is set up for
your phone.
You may also be asked to enter an account and/or authorisation code in order to be
able to make a call (or you may choose to enter a code voluntarily). These are
described next.
If you try to make a call if there are no available Call buttons, you will hear No
More Calls tone instead of ringing tone and you cannot complete the call.
Authorisation Codes
and Account Codes
Account codes ensure your call is charged to the proper account or department.
Authorisation
codes
ensure
you are authorised to make outside calls. You may be
required to enter a code before a call can be made (these are referred to as “forced”
codes), or you may voluntarily enter a code before or during a call.
Entering
Account
Codes
If you are asked to enter an account code when you select an outside line, press the
programmed [ACC] button or the soft button for the ACCT option on the LCD
panel. Enter the code using the dial keys. To voluntarily enter a code before making
a call or during a call, press the [ACC] button or dial [4] [7] and enter a valid code,
press the [ACCT] button again.
