Search for All Users Who Have a Voice Over IP Phone

Sample script that searches Active Directory for all the users who have an IP phone number. The ipPhone attribute is replicated to the Global Catalog. This means you can connect to a Global Catalog server and search across the forest for all users who have a VoIP phone. Note that this attribute is not automatically populated any time you create a user account.
