ARS is turned on by selecting under which circumstances it operates – either when an extension user
makes a call using the Idle Line Access method, or when any CO Line Access method is used. (

Leading Number Exception Table
Once ARS is activated, store the telephone numbers that will bypass ARS in the Leading Number
Exception Table.
Note that the first few digits (leading number) of a telephone number, such as an area code or local
exchange, can also be stored, so that all calls to those areas or exchanges are exempted from ARS.
Also note that the CO Line Access number is always ignored by ARS and does not need to be
programmed here.
