Party Line is a Facebook application that lets you voice chat with your Facebook friends. When you add Party Line to your Facebook account you'll be able to create group chats with up to 5 people at one time. Set up a chat with your friends. Then you can all get on Party Line at the same time and chat together.

Create as many party lines as you want. Create one for your close friends, another for your work friends and another for your football buddies. It's completely free. There's no software to download and you don't need to remember any passcodes to get into the Party Line chat of your making.
