3.12 Dial Plan
Dial plan defines the rule of dial. The syntax of dial plan for C2W is closely similar as the
corresponding syntax specified by MGCP and MEGACO.
Dial plan is stipulated by the below configurable parameters:
Interdigit Long Timer——refer to Interdigit long timer for more detail description
Interdigit Short Timer——refer to Interdigit short timer for more detail description
Dial Plan
Dial plan contains a series of digit sequences, separated by the ‘|’ character. The collection of
sequences is enclosed in parentheses ‘(‘ and ‘)’.
Default: (*xx.|xxxxxxxxxxxx.)
When user dials a series of digits, C2W will response in below way:
• No candidate sequences matched, the number will be rejected and “call ended” will be displayed
on the screen. For instance, if the default dial plan only supports digits, any ‘*’ character or letters
input will be rejected.
More than one candidate sequences matched, C2W will wait for more digits input.
When input timeout occurs, C2W will dial the digits input already.
When input ‘#’ character, C2W will dial the input digits immediately.
Digit Sequence Syntax:
‘x’: Matches any one numeric digit (‘0’ ... ‘9’)
‘[]’: Numeric ranges are allowed within ‘[]’. For example, [389] means ‘3’ or ‘8’ or ‘9’, [3-6] means
‘3’ or ‘4’ or ‘5’ or ‘6’ , [235-8*] means ‘2’ or ‘3’ or ‘5’ or ‘6’ or ‘7’ or ‘8’ or ‘*’.
‘.’ ：Any element can be repeated zero or more times by appending a ‘.’ character. For example, 01.
matches 01,011,0111,01111,...,011111111...etc.
‘<>’: subsequence substitution. For example, ‘<8:1650>xxxxxxx’ would match ‘85551212’ and the
first digit ‘8’ will be replaced by ‘1650’ and ‘16505551212’ will be dialed.
‘,’: An “outside line” dial tone can be generated within a sequence by appending a ‘,’ character
between digits. Thus, the sequence “9, 1xxxxxxxxxx” sounds an “outside line” dial tone after the
user presses ‘9’, until the ‘1’ is pressed.
‘!’: A sequence can be barred (rejected) by placing a ‘!’ character at the end of the sequence. For
example, “137xxxxxxxx!” will forbid numbers which have 11 digits and start by 137 to be dialed.
Page 17
WiFi SIP Phone
C2W User Manual
23
Example:
(xxxxxxx|[*#]xxxx|9,1xxxxxxxxxx|00xxx!) contains 4 subsequences:
1. Allow to dial numbers with 7 digits
2. Allow to dial numbers with 4 digits and start by ‘*’ or ‘#’
3. Allow to play an “outside line” dial tone after pressing ‘9’ and dial numbers with 11 digits and
start by 1
4. Forbid to dial numbers with 5 digits and start by 00
