Calling a phone number

To place a call to a phone number in Gmail after installing the voice and video chat plug-in just follow the steps below. If you'd like to make a voice or video call from one computer to another, follow these instructions.
To place a call to a landline or wireless phone number:

1. In your chat list, click the Call phone link
2. In the resulting Call window, dial the number you wish to call (you can use your mouse or your keyboard's number pad)
3. Click the Call button

If you would like to make an international call, you can do so using the current Google Voice calling rates. Just add credit and dial the number. You can select the applicable country code by clicking the the flag drop down or by typing it directly into the window (i.e. +55 for Brazil).
If there is already a phone number assigned to a contact, it will auto-fill in the Call window if you begin to type in that contacts name. Alternatively, you can initiate a phone call from a text chat window by clicking the phone icon.
When you're done with your call, just click the End button. If you wish to call the same number back immediately, you can click the Redial button after the call has ended.
