    • Prefix rules are recommended to be below your main rules in the rule.

    Call to Numbers with a length of: "13" for 10 Digit and "14" for 11 Digit

    Strip digits: 3

    • This strips off the 100 so it does not get sent in your call to Voxtelesys.

    Prepend: "+1" for 10 Digit and "+" for 11 Digit
