We all use computers every day for work or fun. Traditionally, computers were not used for placing calls. We relied on a separate phone to ring someone up. However, with technological advancements, the landscape of communication is also changing. Today, you can make a phone call from a computer without switching to your phone. Making phone calls from a computer simplifies your communication process to connect with your colleagues, team, or friends while working.

How Does a Phone Call from a Computer Work?

A phone call from a computer works by using Voice Over Internet Protocol (VoIP). It uses a broadband internet connection instead of traditional phone lines or mobile networks.

When you speak, your voice (analog) is converted into digital data using an analog-to-digital (ADC) converter. The converted digital data is broken into small packets and tagged with information about who the caller and receiver are before being sent over the internet.

When the data reaches the VoIP provider’s server, it directs your call based on the information about who the receiver is. When it reaches the receiver, the end device collects the digital packets, reassembles them, and converts them into analog signals using a digital-to-analog (DAC) converter.

This establishes a connection, and you can hear the other person through your computer. So, a phone call over a computer is just VoIP at work.

What Do I Need to Make a Phone Call from My Computer?

You need a good internet connection, speakers, and microphones to make a phone call from your computer or receive it. The broadband internet is the foundation for all calls made through computers.

Test the call quality in different network conditions to choose an app that consistently delivers a superior audio experience.

Additional Features

Many apps offer more than just voice calls, including video calls, screen sharing, and file sharing. Consider what additional features you might need, such as conference calling, voicemail, or encryption for security. These extras can significantly enhance your communication, especially for business users.
