Min-SE
Enter the minimum number of seconds the Device lets a SIP session remain idle (without

21.4.2
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 Device makes the call.
The 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 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 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 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.
