1.4.2. Name

The name of the Dialplan is displayed here.

1.4.3. Destination number

This is a regular expression for the dialed phone number.

Consider an example:

^\+?3?8?(0[679]3\d{7})$

This regular expression describes the codes of the Ukrainian mobile operator lifecell.

This operator has three codes: 63, 73, and 93. Users can dial telephone numbers both in the international format +38063ххххххх, in the national format 063ххххххх, and the outdated format: 8063ххххххх.

With the above expression, we close all dialing possibilities.

Let's consider in more detail:

• ^ - the beginning of the regular expression. This is a required character!
• \+ - further check for the presence of +, since this is a service character, we escape it with \
• ? - the question mark means optional. That is, the presence of + in the number is not obligatory;
• 3? - number 3, the presence is optional;
• 8? - number 8, the presence is optional;
• ( - the beginning of the match block. Everything that will be in parentheses goes into service variables and can be used in call routing;
• 0 - the obligatory presence of the number 0;
• [679] - one digit from those entered in [ ]. That is either 6, 7, or 9;
• 3 - the obligatory presence of the number 3;
• \d - this sign indicates the presence of any digit. The same if it were written in the following way: [0-9] - any one digit from the range from 0 to 9;
• {7} - the number in { } indicates the number of repetitions of the previous expression. This means that there should be 7 of any digits in total;
• ) - the ending of the match block;
• $ - the end of the regular expression. This is a required character!

The expression may also contain the following symbols:

• | - Or operator. For example, 7|8 - can be 8 or 7 - one digit out of two;
• {10,12} - the number of repetitions of the previous expression. But, in this case, our range is at least 10 and not more than 12.
