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 ZyXEL Device makes the call.
The ZyXEL Device 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.
• {dialed-number:translated-number} indicates the number after the colon
replaces the number before the colon in an angle bracket {}. For example,
({:1212} xxxxxxx) means the ZyXEL Device automatically prefixes the
translated-number “1212” to the number you dialed before making the call. This
can be used for local calls in the US.
({9:} xxx xxxxxxx) means the ZyXEL Device automatically removes the
specified prefix “9” from the number you dialed before making the call. This is
always used for making outside calls from an office.
(xx{123:456}xxxx) means the ZyXEL Device automatically translates “123” to
“456” in the number you dialed before making the call.
• Calls with a number followed by the exclamation mark “!” will be dropped.
• Calls with a number followed by the termination character “@” will be made
immediately. Any digit (0~9, *, #) after the character will be ignored.
In this example dial plan (0 | [49]11 | 1 [2-9]xx xxxxxxx | 1 947 xxxxxxx !), you
can dial “0” to call the local operator, call 411 or 911, or make a long distance call
with an area code starting from 2 to 9 in the US. The calls with the area code 947
will be dropped.
