Works with CiviCRM 4.4. It might not be supported anymore.
Displays phone numbers that are likely to be invalid (in the UK), or that look to be incorrectly assigned as either a mobile phone number or a landline number.
Allows deletion and changes to any phone number through the interface.
USAGE: in the menu under 'Contacts'.
All feedback and additions welcome.
