The PC-to-phone feature makes local and international calls through a Verizon Internet telephony service that has been expanded to include Austria, Belgium, Finland, Ireland, Italy and the Netherlands. Called Verizon Web Calling, the service previously covered only the United States, the United Kingdom, Germany, France and Spain.
Windows Live Messenger also builds a unified contact list that draws on information from other applications.

MSN Messenger, the parent application of Windows Live Messenger, offers PC-to-PC calling with video capability and PC-to-mobile instant messaging, but no landline-calling capabilities.

Included in these new applications are Windows Live Mail--the next-generation Hotmail--and Windows Live Search.
Windows Live Messenger will compete with instant-messaging services from AOL, Yahoo and Google, which also offer various forms of PC-to-phone capabilities.
Last week, AOL announced that it will launch this month
