To solve this problem you need to check the phone number filter.

  • Phone number filter - enter the phone numbers that will be allowed for use. Leaving the field blank will not set the filter.

You may use the following characters:

  • Figure - enter the figure that you want to allow;
  •  ? - enter any figure;
  • * - enter a set of figures;
  • [x1-x2] or [x1,x2,x3] - - enter a range of allowed figures in direct order.

Example:

  • If you set "7*", those phone numbers starting with 7 will be allowed.
  • If you set "?950*", the phone numbers starting with any digit followed by 950 and any digits will be allowed.
  • If you set "7[2-5]*", the numbers starting with 7 followed by a digit from 2 to 5 and a set of any digit will be allowed.
  • If you set "[2,5,8]*", the phone numbers starting with 2,5 or 8 followed by any digits will be allowed.
