The LocalNumber property sets or returns the local phone
number that is specified in the current phonebook entry. If the
CountryCode property has a value of zero, then the local
number is dialed to connect to the server. If the
CountryCode property is set to a valid country code, then
RAS will also use the country and area code values when dialing the
phone number.
Note that this property only determines the local phone number
for the phonebook entry, and can be overridden by setting the
PhoneNumber property to a specific value.
