• No candidate sequences matched, the number will be rejected and display “call ended” on the
screen. For instance, the default dial plan only supports digits. And ‘*’ character or letters will be
rejected when input them.
More than one candidate sequences matched, Rainbow2 will wait for more digits input.
When input timeout occurs, Rainbow2 will dial the input digits.
When input ‘#’ character, Rainbow2 will dial the input digits.
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.
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
