The Phone tab contains the user’s phone numbers. To add a phone number, do the following:
Right-click on any area in the phone table, and then click Add in the shortcut menu.
Type the phone number, select the type of phone number that it is (e.g., Home, Work, Fax, etc.), and then click OK.
If you are adding more than one phone number, you can select one of the numbers as primary by selecting the Primary option next to that number. Setting a phone number as primary is only a visual indicator for the person viewing the information.
