Mediant 500 E-SBC

Inter-digit timeout expires (e.g., for open numbering schemes). This is defined using
the TimeBetweenDigits parameter. This is the time that the device waits between each
received digit. When this inter-digit timeout expires, the device uses the collected
digits to dial the called destination number.

Digit string (i.e., dialed number) matches one of the patterns defined in the digit map.
Digit map (pattern) rules are defined using the DigitMapping parameter. The digit map
pattern can contain up to 52 options (rules), each separated by a vertical bar ("|"). The
maximum length of the entire digit pattern is 152 characters. The available notations are
described in the table below:
Table 25-1: Digit Map Pattern Notations
Notation Description
[n-m] Range of numbers (not letters).
. (single dot) Repeat digits until next notation (e.g., T).
x Any single digit.
Note: This notation does not apply to some scenarios when using the star (*)
or hash (#) key. For example, the key sequence of ** must be presented in the
dial plan as *x.s (instead of xx).
T Dial timeout (configured by the TimeBetweenDigits parameter).
S Short timer (configured by the TimeBetweenDigits parameter; default is two
seconds) that can be used when a specific rule is defined after a more general
rule. For example, if the digit map is 99|998, then the digit collection is
terminated after the first two 9 digits are received. Therefore, the second rule
of 998 can never be matched. But when the digit map is 99s|998, then after
dialing the first two 9 digits, the device waits another two seconds within which
the caller can enter the digit 8.
Below is an example of a digit map pattern containing eight rules:
DigitMapping = 11xS|00[1-
7]xxx|8xxxxxxx|#xxxxxxx|*xx|91xxxxxxxxxx|9011x|xx.T
In the example, the rule "00[1-7]xxx" denotes dialed numbers that begin with 00, and then
any digit from 1 through 7, followed by three digits (of any number). Once the device
receives these digits, it does not wait for additional digits, but starts sending the collected
digits (dialed number) immediately.
