You misunderstand completely.
The "dial plan" in a phone defines what pattern of numbers should
automatically send a phone number to the PBX/phone system.
Most phones use some subset of regular expressions to define the number
pattern. Here is an example from a spa841:
*xx|[3469]11|0|00|[2-9]xxxxxx|1xxx[2-9]xxxxxxS0|xxxxxxxxxxxx.
The first will match an asterisk followed by two numbers and dial. The
second will match, 411, 611, 911 and 311. For more I suggest you read
about regular expressions and your phone documentation for what subset
of regular expressions it supports if any.
