Yahoo! Phone In is a premium Yahoo! Messenger feature that allows your friends to call your PC from a regular phone or a mobile phone.
Tips:
Before you answer a call, use the Call Setup Assistant,
as described in the Introducing Yahoo! Messenger’s Call Features tutorial,
to be sure that your microphone and speakers are set up properly.
The Yahoo! Phone In service isn’t available when conversing
with Windows Live™ Messenger contacts.
If you’re signed in to Yahoo! Messenger and a friend calls your computer from his or her phone, you’ll see a pop-up notification of the call on your computer screen.

Respond by clicking one of the buttons:
Accept: the connection is made, and you can begin talking just like you do on the telephone.
Decline: the caller doesn't know you've declined.
If you accept the call, the Call window opens and begins timing the length of the conversation.

To end the call, click the End call button.

Tips: The Call notification window provides some useful information
and features:
Yahoo! Voice supports caller ID, so the notification displays
the phone number of the person calling you. If the person has a Yahoo! ID, the
ID displays as well, even if the person isn’t in your Yahoo! Address Book.
Your phone number—the one attached to your ID—displays
in the title bar. This information is useful if you want to know
which of your many Phone In numbers the person is calling.
Check Mute Ringtones to turn off
the ringing on your computer. This also unchecks the Play
a ringtone when I receive a call option in the Calling
& Audio category of the Preferences window.
Another call coming in? Put your current caller on hold.
