How to Make Phone Calls From a Computer?

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 whom 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 whom 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.

To make a phone call from your computer, you need a stable internet connection, a microphone, and a calling app. A strong internet connection ensures clear, uninterrupted conversations, while a built-in or external microphone lets you speak comfortably. Many users also prefer using headphones for better audio quality during longer or professional calls.

Once you’ve got those basics, download a reliable free calling app like Skype, Messenger, or WhatsApp. These platforms let you make free calls from a computer to other users on the same app, and some even offer free internet calling to numbers in select countries. Just install your chosen app, sign in, and start calling directly from your desktop or laptop.

Find and open the “Phone Link” app from the search bar on your Windows taskbar. Download it from the Microsoft Store if you do not have it installed.

Log in to your computer and phone using the same Microsoft account. Pair your devices with Bluetooth. A QR code will appear on your PC screen; scan with your phone.

Grant permission to allow your PC to handle calls. In the Phone Link app, navigate to the ‘Calls’ section.

From the ‘Calls’ section, dial a number or select a contact and initiate the call. Your PC’s built-in or external microphone and speakers are utilized for audio.

A notification will pop up on your PC when you receive calls. You can answer directly using your computer as a phone.

You can make phone calls from a macOS or an Apple computer using the iOS FaceTime app. However, you first need to integrate your iPhone and computer through iCloud.

2. Enable Calls on Other Devices: On your iPhone, navigate to Settings > Phone and select “Calls on Other Devices.” Activate the option to “Allow Calls on Other Devices.”

3. Launch FaceTime: Open the FaceTime app on your computer.

4. Make a Call: Call any contact by typing their name, email, or phone number in the search field. To call someone not in your contacts, add them to your contact list or place the initial call from your iPhone.
