title: UI Phone number accepting - international format
body: <p>Are there any standards for phone number across the world.
  I would like to create one UI to accept the phone number
  Depending on country the phone number accepting dialog should be changed like in US it should be +1-408-567-9822
  There are different such types of conventions getting followed across the world.
  Are there any location to get all standards or code to format the phone numbers.</p>
