Creating a Dialling Rule

To set up a rule a pattern that the dialled number must match needs to be defined followed by an action to be taken on the dialled number once a match is detected. An action can be removing a prefix, removing a prefix or removing a prefix followed by adding a prefix.

The following characters can be used to generate a match pattern.

0,1,2,3,4,5,6,7,8,9 any digit

* # + any of these three symbols

[-] matches a range of symbols eg [45-9] matches any of these digits 4,5,6,7,8,9

x matches any of the above digits or symbols

? specifies that the previous character can be repeated 0 or more times

Example 1

Match Number +44x?

Remove Prefix +44

Add Prefix 9

Any number starting with +44 will have the +44 replaced with 9 so the number +44773764181 will be dialled as 9773764181

Example 2

Match Number xxxxxx780[1-9]

Add Prefix 7

Any 10 digit number with the last 4 digits being 7801- 7809 will have a prefix of 7. So 5003007804 is dialled as 75003007804

Example 3

Match Number 0xxxxxxxxxx

Remove Prefix 0

Add Prefix +44

Any eleven digit number starting with 0 will have the zero removed and replaced with +44
