How to Use a
Dial Map
Let’s say you are in an office and you want to call a co-worker’s 3-digit
extension. You could build a Dial Map that said “after the user has
entered 3 digits, make the call”. The Dial Map could look as follows:
xxx
This Dial Map specifies that after the user has entered any three digits,
the call is placed. You could refine this Dial Map by including a range
of digits. For example, you know that all extensions in your company
either begin with 2, 3, or 4. The corresponding Dial Map could look as
follows:
[2-4]xx
You have just entered a range of digit. Thus, if the number you dial
begins by anything other than 2, 3, or 4, the call will not be placed and
you will get a busy signal. Another way to achieve the same result
would be:
[234]xx
