Currently I am cleaning up Phone Types with No Contact Information within however in Global Change there is no way to delete Phone Types you can only add or replace which will not work in either case. I would imagine there are other cases similar to this in global change which would benefit all 3 options.
Would the delete phone plug in work for you? I found it with a simple search for "delete phone type" on blackbaud.com. https://www.blackbaud.com/kb/index?page=content&id=BB21303&actp=search&viewlocale=en_US&searchid=1426720341744
I've used the delete phone type for this purpose before. You have to be careful though -- best to change all the phones you want to delete to a type like DELETE. YOu don't want to accidentally delete all HOME phones. There are no options to connect to a query or anything like that with this plugin.
