3.5.6 Digitmap
The destination number will be sent all in one time for SIP application, digitmap is used to determine
exactly when there are enough digits entered from the user to place a call. If the number length of suited
route item is fixed, the number will be sent when specified number of digits is received; the call will be
disconnected when inter-digit timeout expires. If the number length of suited route item is indefinite,
there are 3 ways to determine whether the digits is enough, press pound(#) key, timeout expires or
digitmap comparing. If digits dialed partly matching with digitmap patterns, continue waiting of number
receiving. If they match, send the number immediately. If not, send the number immediately too, in order
to play the prompts.

Digitmap Characters
Character Description
0
～
9 Indicates specific digits in a telephone number expression.
X Wildcard, matches any digit, excluding “#” and “*”.
* Digit star
# Digit pound
- Connects the start and the end of a range
[] Indicates the a range of numbers(not letters).
. Matches an arbitrary number of occurrences of the
preceding digit, including 0.
| Indicates a choice of matching expressions (OR).
T
Inter-digit timeout expires
S Short timer expires, usually place at the middle of an
expression
Digitmap Example: 8XXXXXXX|1[0-24]0|2[18].3|3XXSXX|[0-9*#][0-9*#][0-9*#].#|[0-9*#].T
l “8XXXXXXX” denotes numbers start with 8, the length is 8.
l “1[0-24]0” denotes numbers include 100, 110, 120 and 140.
l “2[18].3” denotes numbers that start with 2 and end with 3, there can be arbitrary length of 1 or 8
after the first digit 2. 23, 213, 2183 is matched.
l “3XXSXX” denotes numbers start with 3, the length can be 3 or 5. If the short timer configured
expires between the third digit and the fourth digit, the number will be sent.
l “[0-9*#][0-9*#][0-9*#].#” denotes numbers end with #, and the length is no less than 2.
