When this user property is set to Y, the employee's home phone number is hidden in the Contact List and Employee List views.
Employees and Administrators can check the Share Home Phone Flag field to show their home numbers and uncheck to hide.
The functionality only hides the value of the Home Phone # field if the Share Home Phone Flag field is set to N and the Employee Flag field is Y.
You can inactivate and modify the values for this user property. You can also create new instances of this user property as needed.
