Select a friend in your contact list and click the Call button to get started. You and the friend you call both need Yahoo! Messenger, plus a microphone and speakers (or headset). If you own a laptop, you probably have these tools already built-in. If not, head over to Yahoo! Shopping to check out some headsets.
Free PC-to-PC calls are unlimited and the quality is so good that you won't believe it's free! PC-to-PC calling is currently available in the following versions of Yahoo! Messenger: Windows, Mac.
If your friend is not available, you can leave them a free voicemail. You can also receive voicemails from friends who miss you when they try to call. Voicemail messages are delivered as attachments in email to the address you choose.
Call regular and mobile phones too
Sign up for a Yahoo! Voice Phone Out account to make calls from Yahoo! Messenger to your friends' regular or mobile phones worldwide for as low as 1¢ a minute. Find out more.
If you don't want to miss calls, even when you're signed out, use the call forwarding feature to send incoming PC-to-PC calls to another phone number like your mobile phone (Yahoo! Voice Phone Out account required). The call is still free for your caller, and you only pay the Yahoo! Voice per minute rate for the forwarded call (as low as 1¢ a minute).

Messenger. Even if you're away from your PC, they can leave a voicemail for you, or you can forward your incoming calls to another number, like your mobile phone. Find out more.
