Integrated Call Costing
Call costing provides a means of establishing costing that the system can apply to outside calls made from
system telephones. Call costing computes charges for a call after it is completed. It does not restrict
dialing as toll restriction does. The system provides several ways of establishing call costing that are as
follows:
•
exception tables for local and long distance calls,
•
office code band tables for local calls,
•
zone call band tables for long distance calls,
•
area code band tables for long distance calls,
•
call rate tables for local and long distance calls.
With this range of costing methods, it is possible to apply reasonable rates for the entire country. The
system applies call costing to a dialed number as described below. Refer to Section 3.16.1 for an
illustration of the call costing process.
You should make a record in Chapter 4 of all programming decisions that you make—it will help you
keep track of what you have done and will help you troubleshoot any problem that might arise later.
NOTE: A lighted LED next to the programming button for the selection indicates the current
configuration. When a single button provides a toggle (on/off) action, the lighted LED
indicates the active feature.
The first step in any programming sequence is to enter the base level. Once in this mode, you can dial the
feature code for any desired configuration. Enter the base level with the following procedure:
press INTERCOM then dial
✳
# 7 4 6
✳
. When you want to end the programming, press the SPEAKER
button to end the programming procedure and return the system to normal operation.
