Windows Live Messenger(MSN)

"Windows Live Messenger is a famous chat client."
By SoftCns Editor: Ta da! It's the next-generation MSN Messenger. Along with everything you already love about Messenger-your contact list, emoticons, instant access to your friends-there are brilliant new ways to connect and share your photos (and other stuff). As always, Windows Live Messenger is free to download Messenger and use most of its features.

Call their phones. Call their PCs.
Call your friends' mobile or landline phones. It's affordable, both within the US and internationally. And calling someone's PC is always free.
