The simplest way to call from your computer

You can make phone calls from your computer using software or a web browser, and you do not need a phone line or special equipment beyond what you already have. Your computer's built-in microphone and speakers (or a headset) handle the audio. The most common routes are VoIP services like Skype, Google Meet, or Zoom, which let you call other people on the same service for free, or call regular phone numbers for a small fee.

If you want to call someone's regular phone number, you will need either a paid VoIP subscription, a service that charges per minute, or a free option like Google Voice (which works in the United States). If you only need to call other people who also have the same app or service installed, most of these are free.

Key Takeaways

  • Skype, Google Meet, Zoom, and similar apps let you call other users of the same service free, using only your computer's microphone and speakers.
  • To call a regular phone number from your computer, you need a paid VoIP service, a pay-per-minute service, or Google Voice (United States only).
  • A headset with a microphone gives you better sound quality than your computer's built-in microphone, especially if you make calls often.
  • Your internet connection speed matters more than your computer's power — a stable broadband connection is what you need.

Free calling apps that work between users

Skype is one of the oldest and most widely used. read it from skype.com, create a free account, and you can call anyone else on Skype at no cost. The other person needs Skype installed too. You can also use Skype's web version in your browser without downloading anything.

Google Meet (meet.google.com) lets you start a video or audio call and send a link to the other person. They do not need a Google account — they can join through the link. Zoom (zoom.us) works the same way: you start a meeting and share the link. Both are free for one-on-one calls with no time limit.

Discord (discord.com) is designed for group chat but works well for one-on-one calls too. It is free and requires only a free account. WhatsApp has a web version (web.whatsapp.com) that lets you make calls through your browser if you have WhatsApp on your phone linked to it.

All of these require the other person to have the same app or service. If you need to call someone's regular phone number, you will need a different approach.

Calling regular phone numbers from your computer

Google Voice is free in the United States and gives you a phone number that rings on your computer. Go to voice.google.com, sign in with a Google account, and follow the setup steps. You can call any U.S. or Canadian number free, and receive calls on that number. International calls cost money, but the rates are posted before you dial.

Skype also lets you buy credit and call regular phone numbers. The cost varies by country and whether you are calling a mobile or landline. You can see the rates before you buy credit.

Vonage, MagicJack, and Ooma are paid VoIP services that give you a phone number and let you call anyone. They charge a monthly fee (usually $5 to $15) and include unlimited calling to the U.S. and Canada. These are better if you make calls regularly, because the monthly cost is lower than paying per minute.

Some services charge per minute instead of a monthly fee. Rebtel and Viber Out work this way — you buy credit and use it to call phone numbers. These are useful if you call only occasionally.

What you need to set up your computer for calling

Your computer needs a working microphone and speakers or headphones. Most laptops have both built in. Desktop computers usually have speakers but may not have a microphone — you can buy a USB microphone for $15 to $40, or use a headset with a built-in microphone.

A headset (headphones plus microphone in one device) is the best choice if you make calls often. It keeps your hands free and blocks background noise better than your computer's microphone. USB headsets plug directly into your computer and cost $20 to $60.

Your internet connection matters more than your computer's power. VoIP calls need a stable broadband connection — cable, fiber, or DSL all work. A connection speed of at least 1 Mbps is enough for one call. If your internet is slow or drops often, calls will sound choppy or cut out.

Test your microphone and speakers before your first call. In most apps, there is a settings menu where you can select which microphone and speaker to use, and a button to test them.

How to make your first call

The steps depend on which service you choose, but the basic flow is the same. First, read or open the app or website. Create a free account if you have not already. Then find the person you want to call — either by their username (if they use the same service) or by their phone number (if you are using a paid service or Google Voice).

Click the call button. The app will use your microphone and speakers. If you are calling someone on the same service, they will see an incoming call notification and can accept or decline. If you are calling a regular phone number, the call will go through to their phone just like a normal call.

Speak normally — you do not need to do anything special. If the sound is too quiet or too loud, most apps have a volume slider during the call. If the other person cannot hear you, check that your microphone is not muted (there is usually a mute button on screen).

Troubleshooting common calling problems

If the other person cannot hear you, first check that your microphone is not muted. Look for a microphone icon with a line through it — click it to unmute. Then go to the app's settings and make sure the correct microphone is selected. If you have multiple microphones (built-in and USB, for example), the app might be using the wrong one.

If you cannot hear the other person, check that your speakers or headphones are not muted and that the volume is turned up. In the app settings, make sure the correct speaker is selected. If you are using headphones, make sure they are plugged in or connected.

If the call keeps dropping or sounds choppy, your internet connection may be too slow or unstable. Close other apps that use the internet (streaming video, large downloads) and try again. If the problem continues, restart your router by unplugging it for 30 seconds and plugging it back in.

If the app crashes or will not open, try restarting your computer. If that does not work, uninstall the app and read it again from the official website — not from a third-party source.

When to call a professional

If your microphone or speakers are not working and you have checked that they are plugged in and turned on, the hardware may be broken. A computer repair shop can test them and replace them if needed. If your internet connection is the problem, contact your internet provider — they can check your connection speed and stability.

If you need a phone number that works like a regular landline (so people can call you back and it shows up on their caller ID), a paid VoIP service like Vonage or Ooma is the right choice. These services can also port an existing phone number if you want to keep the same number you have now.

Frequently Asked Questions

Do I need to pay to call someone on Skype or Google Meet?

No, calling another Skype user or Google Meet user is free. You only pay if you want to call a regular phone number. Both services let you call other users of the same service at no cost.

Can someone call me back on my computer?

Only if they also have the same app and know your username. If you want a phone number that anyone can call, you need Google Voice (United States) or a paid VoIP service like Vonage or Ooma.

What if my internet goes out during a call?

The call will drop. Unlike a regular phone line, VoIP calls need an active internet connection the whole time. If your internet is unreliable, consider a paid VoIP service that includes a backup option, or keep a mobile phone as a backup.

Can I use my computer to call international numbers?

Yes, but it costs money. Google Voice, Skype, and other services charge per minute for international calls. The rates vary by country and are shown before you dial. Some paid VoIP services include international calling in their monthly fee.

Is a computer call as clear as a regular phone call?

Usually yes, if your internet connection is good and you are using a decent microphone. A headset with a microphone gives better sound than your computer's built-in microphone. If your internet is slow or unstable, the call may sound choppy or have delays.
