Phone Dialer overview
Phone Dialer allows you to make voice calls, video calls, and conference video calls from your personal computer.
To make a voice call, all you need is the recipient's phone number, IP address, or DNS (Domain Name System) name. Phone Dialer lets you make calls with a telephone connected to your computer, through a modem, over a network, through a telephone switch connected to your local area network (LAN), or an Internet address.
In order to communicate using Phone Dialer, you will need a sound card and microphone. A camera for video calls is optional.
You can still participate in a video conference without a camera. In this case, you can view the participants that have cameras, but you will only be heard. If you have speakers but do not have a microphone, you can view and hear a conference, but you cannot participate.
With Phone Dialer, you can also test the setup of your computer-telephony hardware, such as a voice modem or a phone switch connected to your LAN, by dialing the number and seeing if the number lets you connect.
To receive calls, you must have Phone Dialer running. When you make or receive a call, a dialog box appears in the upper-left corner of your screen. If the person you are talking to has a video camera installed, the dialog box shows a video image of the person.
The active call window also contains a button that lets you access a keypad to manually dial numbers.
