21.2.1 Dial Plan Rules
A dial plan defines the dialing patterns, such as the length and range of the digits for a telephone
number. It also includes country codes, access codes, area codes, local numbers, long distance
numbers or international call prefixes. For example, the dial plan ([2-9]xxxxxx) does not allow a
local number which begins with 1 or 0.
Without a dial plan, users have to manually enter the whole callee’s number and wait for the
specified dialing interval to time out or press a terminator key (usually the pound key on the phone
keypad) before the Router makes the call.
The Router initializes a call when the dialed number matches any one of the rules in the dial plan.
Dial plan rules follow these conventions:
• The collection of rules is in parentheses ().
• Rules are separated by the | (bar) symbol.
• “x” stands for a wildcard and can be any digit from 0 to 9.
• A subset of keys is in a square bracket []. Ranges are allowed.
For example, [359] means a number matching this rule can be 3, 5 or 9. [26-8*] means a number
matching this rule can be 2, 6, 7, 8 or *.
• The dot “.” appended to a digit allows the digit to be ignored or repeated multiple times. Any digit
(0~9, *, #) after the dot will be ignored.
For example, (01.) means a number matching this rule can be 0, 01, 0111, 01111, and so on.

Select this if you want to use the pound key (#) to tell the Router to make the phone
call immediately, instead of waiting the number of seconds you selected in the
Dialing Interval Selection field.
If you select this, dial the phone number, and then press the pound key. The Router
makes the call immediately, instead of waiting. You can still wait, if you want.
