Syntax for Digit Maps and Dial Plans

Digit maps and dial plans are defined using special syntax rules, configured in the 'Dialing'
screen (refer to 'Configuring Dialing Parameters' on page 43).
Digit Maps: A phone's digit map allows MP-20x to know when an entered telephone
number is complete and therefore, when it should initiate the call. If the phone digit
map is defined incorrectly, MP-20x might start to dial before the telephone user has
entered all the required digits. A digit map is defined either by a (case insensitive)
"string" or by a list of strings. Each string in the list is an alternative numbering
scheme, specified either as a set of digits or as an expression over which MP-20x
attempts to find a shortest possible match. The syntax that can be used in each
numbering scheme is described in the table below.
Dial Plans: A dial plan translates specific patterns into specific SIP destination
addresses. For example, dial plan rule "4xxx=Line_\\\@10.1.2.3" sends a dialed
number consisting of the digit 4 followed by any three digits to IP address 10.1.2.3.
The syntax of the pattern on the left of the '=' sign is described in the table below.

Type
Digit A digit from "0" to "9".
DTMF A digit, or one of the symbols "A", "B", "C", "D", "#", or "*". Extensions may be
defined.
Wildcard The symbol "x" which denotes any digit ("0" to "9").
One or more DTMF symbols enclosed between square brackets ("[" and "]").
Range
Subrange Two digits separated by a hyphen ("-") which matches any digit between and
including the two. The subrange can only be used inside a range construct, i.e.,
between "[" and "]".
Position A period (".") which matches an arbitrary number, including zero, of occurrences
of the preceding construct.
For example:
[2-9]11|0|100|101|011xxx.|9011xxx.|1[2-9]xxxxxxxxx|91[2-9]xxxxxxxxx|9[2-
9]xxxxxx|*xx|[8]xxxx|[2-7]xxx
[2-9]11: 911 rule: 211, 311, 411, 511, 611, 711, 811, 911 are dialled immediately
0: Local operator rule
100: Auto-attendant default extension
101: Voicemail default extension
011xxx.: International rule without prefix
9011xxx.: International rule with prefix
1[2-9]xxxxxxxxx: LD rule without prefix
91[2-9]xxxxxxxxx: LD rule with prefix
9[2-9]xxxxxx: Local call with prefix
