          Specifies the telephone number for the server to call back
          on. Syntax
          [form.]object.CallbackNumber [ =
          number ] Remarks
          Setting the CallbackNumber property specifies that the
          server should call the user back at the given telephone number. This
          property is ignored unless the user has "Set By Caller"
          callback permission on the server. Assigning an asterisk to this
          property causes the number stored in the phone book entry to be used
          for callback. Data Type
