Dialplan (Cont’)
Prefix and Strip Digits
When dial command comes with “Prefix” and “Strip Digits”, dial rule can be modified automatically to match
with the command. In this example, we’ll show the command “Dial Extension”.
In this dial rule, [123]XX, it matches any dial digits or digits send with 3 digits starting with “1” or “2” or “3”,
that’s mean any digits within 100 – 399. With “Dial Extension (according to dial rule)”, Prefix set to “5” and no
strip digits. The system will dial the extensions 5100 – 5399, since the “Prefix” setting adds the specified digit
“5” in front of the dialed digits or digits send.
Here is another example, with dial rule
76XX
, prefix “1” and strip digits “2”, the system will convert the dial
string from 76XX to 1XX, since strip digits removes the number of digits specified (in this case is 2) from the
front and add the prefix “1” in front.
