How to Use a Digit Map Reference Manual (SIP Version)
Mediatrix 1204 245
Combining Several Expressions
You can combine two or more expressions in the same digit map by using the “|” operator, which is equal to
OR.
Let’s say you want to specify a choice: the digit map is to check if the number is internal (extension), or external
(a local call). Assuming that you must first dial “9” to make an external call, you could define a digit map as
follows:
([2-4]xx|9[2-9]xxxxxx)
The digit map checks if:
the number begins with 2, 3, or 4 and
the number has 3 digits
If not, it checks if:
the number begins with 9 and
the second digit is any digit between 2 and 9 and
the number has 7 digits
Using the # and * Characters
It may sometimes be required that users dial the “#” or “*” to make calls. This can be easily incorporated in a
digit map:
xxxxxxx#
xxxxxxx*
The “#” or “*” character could indicate users must dial the “#” or “*” character at the end of their number to
indicate it is complete. You can specify to remove the “#” or “*” found at the end of a dialed number. See
“Setting up Digit Maps” on page 246 .
Using the Timer
You can configure the Timer. See “Digit Maps Timeouts” on page 247 for more details. It indicates that if users
have not dialed a digit for the time defined, it is likely that they have finished dialing and the Mediatrix 1204
can make the call. A digit map for this could be:
[2-9]xxxxxxT
Calls Outside the Country
If your users are making calls outside their country, it may sometimes be hard to determine exactly the number
of digits they must enter. You could devise a digit map that takes this problem into account:
001x.T
In this example, the digit map looks for a number that begins with 001, and then any number of digits after that
(x.).
Example
Table 156 on page 243 outlined various call types one could make. All these possibilities could be covered in
one digit map:
(0T|00T|[1-7]xxx|8xxxxxxx|#xxxxxxx|91xxxxxxxxxx|9011x.T)
Note:
Enclose the digit map in parenthesis when using the “|” option.
Note:
When making the actual call and dialing the number, the Mediatrix 1204 automatically removes the
“T” found at the end of a dialed number, if there is one (after a match). This character is for indication
purposes only.
