Parameter Description
Digit Map
[voip/signalling/sip/digit_map]
Enables the administrator to predefine possible formats (or
patterns) for the dialed number. A match to one of the
defined patterns terminates the dialed number.
The valid value can be up to 256 characters.
There are two main formats for the digit map configuration.
The formats are distinguished by the separator ‘;’ or ’|’.
Using ‘|’ separator: The following constructs can be
used in each numbering scheme:
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 matches any digit
("0" to "9").
* Range: One or more DTMF symbols enclosed
between square brackets ("[" and "]").
Sub range: Two digits separated by hyphen ("-")
which matches any digit between and including the
two. The subrange construct 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
This example includes the following rules:
[2-9]11: 911 rule: 211, 311, 411, 511, 611, 711,
811, 911 are dialed immediately
0: Local operator rule: After dialing "0" the phone
waits T seconds and then completes the call
automatically
100: Auto-attendant default extension
101: Voicemail default extension
011xxx.: International rule without prefix
