| Placing a PC-to-PC Call | Receiving a PC-to-PC Call | Placing a Call on Hold |
You can place an Internet call from your PC to another Messenger user’s PC anywhere in the world, and at no cost.
Tips:
You can’t place PC-to-PC
calls with Windows Live™ Messenger contacts.
If you haven’t already done so, 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.
You can initiate a PC-to-PC call in several ways:
Begin typing the person’s name in the Contact Search Bar. If the name is in your Messenger List, Messenger displays the full name and communication options. Select Call Computer from the pull-down list.

Tip: If the person you want to call isn’t in your list, type
the person’s Yahoo! ID,
then select Call Computer from the pull-down
list. Some Yahoo! IDs have domains other than @yahoo.com,
such as @sbcglobal.net or @verizon.net.
When typing these IDs, be sure to add the full domain (person1@sbcglobal.net, person2@verizon.net).
You don’t need to type the @yahoo.com domain. The person
must have Messenger 7 or higher installed to receive your call or
for you to leave a message.
Click the Phone icon on a friend’s contact card and select Call computer from the displayed menu.

Tip:
If
you have signed up for Yahoo! Phone Out,
the menu includes additional calling options, like the ability to
call your friend’s mobile phone from your PC. To learn more about
this premium service, go to Yahoo! Voice.
If you’re already having an IM conversation with the contact you want to call, click the Call button in your IM window.

Tip:
If
you have Yahoo! Phone Out, click the arrow to the right of the Call button
to choose other calling options.
All of these actions open the IM window (if it isn’t already open) in calling mode, and the timer begins timing the call.

Your contact can accept or decline the call or accept instant messaging (IM) only.

If your contact clicks:
Accept: The connection is made, and you can begin talking just like you do on the telephone.
Decline: The call isn’t completed.
IM Only: The call ends, and you return to the IM window in conversation mode. You and your contact can type messages as usual.
Tip: If the person you’re calling has Open Talk enabled, and she isn’t connected to another call, you’ll hear one ring and then Messenger will automatically connect you without waiting for the other person to accept. She won’t even see the incoming call popup window. You can begin talking just as if she accepted the call.
If the contact accepts the call, the IM window continues to time the call.
When you’re finished talking, click the End Call button.

The call is disconnected, and the IM window returns to conversation mode, A message informs you of the length of the call along with the time and date.

If you’re interrupted while talking, you can put your contact on hold.
