The string of numbers that make up a phone number is automatically validated and formatted for a specific territory by applying a series of regular expressions.

Before you begin

Role required: admin

About this task

The number is first validated against the phone validations that have been defined for the territory, and in the order specified by the Order field. To be valid, the number must match the regular expression defined in the Condition field for at least one phone validation.

After a number has been validated, the Condition expression for each format defined for the territory is applied to the number in the order determined by the Order fields. The Pattern and Format regular expressions are applied to produce a phone number that is formatted correctly for the territory.

The Sys Phone Territory screen allows administrators to edit the display rules for a given territory. Administrators may want to modify the Active, Display, or Order fields. To edit the display rules for a territory:

Procedure

  1. Navigate to All > System Policy > Rules > Telephone Display Rules.
  2. Click a territory Name.
  3. Edit the fields, as appropriate (see table).
  4. Click Update.

    FieldDescription
    Name The unique name of the territory.
    Country calling code The country code for dialing numbers from outside the territory.
    International direct dial The prefix for calling internationally from the territory, such as 00 or 001.
    STD The subscriber trunk dialing code, also know as the direct distance dialing code, which is a sequence of numbers before the telephone number that indicate whether the call is to be routed outside of the local calling area.
    International prefix The prefix required to dial an international call, such as a plus sign (+).
    National prefix The prefix required to dial a local call.
    Active An indicator for whether the territory phone definition is active. If deactivated, this territory unavailable to users.
    Trunk dialing code optional An indicator for whether the STD code is optional.
    STD follows country An indicator for whether the STD code should be displayed to the right of the country calling code.
    Display An indicator for whether to display the territory in the choice list. Clearing this check box removes the territory from the choice list. If an international number is entered for a territory that is not displayed in the territory selector choice list, that territory is temporarily added to the selector choice list for that field only. For example, If the United Kingdom Display field is not selected, the United Kingdom does not appear in the territory selector choice list. However, if the user enters an international number beginning with +44, the United Kingdom is added to the list and the number is formatted and validated accordingly.
    Order The order in which a territory appears in a choice list. Territories are sorted numerically by the number assigned here. If more than one territory is assigned the same number, they are subsorted alphabetically. All territories are assigned a default value of 100. To display a territory at the top of the list, assign a value that is less than 100. To display a territory at the end of the list, assign a value that is greater than 100. For example, if a territory is assigned an order of 500, it is displayed at the end of the list, and if more than one territory is assigned an order of 500, they are listed alphabetically at the end of the list.
