When ARS is selected, the user dials the number (including the area code, if needed), and the
system does the following:
1.
Checks the dialed number and matches the dialing pattern to a route group: The
system checks the route groups in numerical order and selects the first group that
applies to the dialing pattern of the number that was dialed.
NOTE:
If the Emergency Call feature is programmed to use ARS, the emergency calls
will always go through Route Group 1, regardless of route group programming.
2.
Selects a facility group: If all of the trunks are busy, and the station is enabled for ARS
camp on, the call will camp on to the facility group until a trunk is available.
3.
Checks for toll restrictions and outgoing access: Before the number is modified by
the facility group’s dial rules, the system checks the station toll restrictions and outgo-
ing access to determine whether the call is allowed. (All calls placed using ARS are toll
restricted, regardless of whether the selected trunk is subject to toll restriction. How-
ever, Emergency Call feature calls are never toll restricted.) If allowed, the system con-
tinues to the next step. If not allowed, the system sends reorder tones, and the call is not
placed.
4.
Adds or deletes digits according to the facility group chosen: Each facility group has
a programmed set of dial rules that tells the system what to dial. For example, if the
selected route group requires that the number contain “1” but no area code, the dial
rules include the 1 and drop the area code.
5.
Dials the modified telephone number: If the number is allowed, the system seizes an
idle trunk in one of the selected trunk groups, waits for the Dialing Wait After Connect
timer to expire, and then dials the number.
