Combining Several Expressions in a Dial Map
It is possible to combine two or more expressions in the same Dial Map
by using the “|” operator, which is equivalent to OR.
Let’s say you want to specify a choice: the Dial 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 Dial
Map as follows:
[2-4]xx|9[2-9]xxxxxx
The Dial Map checks if:
the number begins by 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 Dial 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.
Using the Timer
The Timer is set at 4 seconds. It indicates that if users have not dialed
a digit for 4 seconds, it is likely that they have finished dialing and the
gateway can make the call. A Dial Map for this could be:
Note: When making the actual call and dialing the number, the
AT-VP504E FXS automatically removes the “#” or “*” found at the end
of a dialed number, if there is one (after a match). Those characters
are for indication purposes only.
