Entering leading digits and assigning actions
What are leading digits?
• Leading digits are the first digit or first several digits of an international
access code, country code, area code or phone number.
• Leading digits can be anywhere from 1–11 characters.
• Leading digits can include numeric characters 0–9 and
The leading digit for long-distance calls within North America is 1. As soon
as you dial 1xxx xxx-xxxx, the system recognizes that you are making a
long-distance call within North America.
To place an overseas call from North America, you would dial 011, followed
by the country code, the area code and the phone number (i.e. 011 xx xx
xxx-xxxx). Once you dial 011, the system recognizes that the caller is
placing an overseas call (011 are the leading digits).
ARS will route or block calls according to the leading digits you define and
the actions you chose in the TalkSwitch Configuration under System
Information -> Auto Route Selection.
