| When used with Windows XP, Windows Messenger provides state-of-the-art computer communications features. With Windows Messenger, you can talk to others over the Internet as you do on a regular phone, and you can use video to see others and let others see you, as you converse . Once you set up your computer hardware and software, you're ready to communicate over the Internet. You have two communication choices: audio only, and audio and video. With audio only, you speak into a microphone and hear the other person's response over your computer's speakers . With audio and video, you send video to others so they receive live images as well as sound. If the contacts you call don't have a video camera, they will see you on their monitor, but you won't see them. Have a Voice or Video Conversation -
