Using the Voice-over-Internet Protocol technology, users with a VoIP program can now make phone calls or video calls over the Internet through any broadband or DSL Internet service provider. VoIP replaces traditional phone lines with faster voice signals and clearer digital quality. If your built-in computer speakers or microphone does not provide enough intensity, you can use external computer speakers to amplify the recipient's voice and a microphone attachment to boost your voice.
Connect your external speakers by plugging the speakers' 3.5 mm audio cable into the headphone jack of your desktop or laptop computer.
Plug the microphone's 3.5 mm audio cable into your computer's microphone jack.
Click on the "Start" menu in the bottom-left corner of the desktop screen and select the "All Programs" option. From the program list, select your VoIP program to load the application.
Access the virtual dial pad on your VoIP program and dial the number you want to call. Press the "Call" button to start the connection.
Speak into computer microphone to communicate with the person on the other line. You will be able to hear the audio from the recipient through the computer speakers you have attached. Once the conversation is over, press the "End" button to end the call.
