note that the CO Line Access number is always ignored by ARS and does not need to be programmed
here.
Calls that are exempt from ARS are connected to the user-selected line, via the default carrier for that line.

In this example:
555, 556, and 567 are local exchanges. (555-XXXX, 556-XXXX, 567-XXXX)
These calls can be made using any carrier, and are therefore exempt from ARS.
3. Leading Number Table
Next, store the leading numbers of telephone numbers that should be routed by ARS, and assign a Routing
Plan to each leading number that will control how calls containing these leading numbers are routed.
When an extension user dials a number which contains a leading number stored in the ARS Leading
Number Table, the call will be routed the corresponding Routing Plan assigned here. Note that the CO
Line Access number is always ignored by ARS and does not need to be programmed here.
Before programming the details of each Routing Plan (explained below), you can simply assign here the
same Routing Plan number to all the different leading numbers which will be routed the same way.
If a dialed number matches two or more leading numbers stored in the ARS Leading Number Table, the
lowest numbered location will have priority.

Additional Number of Digits
In order for calls to be made using the desired carrier, telephone numbers dialed by extension users must
be modified to meet the criteria required by the carrier. (Refer to 5. Carrier Table.) This modification usually
involves removing digits and adding access codes to the beginning of the dialed number.
In situations where a preprogrammed number (such as an Itemized Billing Code) must be added
automatically after the telephone number that was dialed by the extension user, set the Additional Number
of Digits to a value greater than 0.
