Making a call on your computer uses internet-based calling software instead of a phone line
A computer call works through an app or website that sends your voice over the internet to another person's device. You need three things: a program that handles calls (like Skype, Zoom, Google Meet, or Discord), an internet connection, and a microphone and speakers (most laptops have these built in). The person you're calling needs the same app on their device, or in some cases, they can join through a link you send them.
The basic process takes less than a minute: open the app, find the person's name or number in your contacts, click the call button, and wait for them to answer. If they're not using the same app, some services let you call their regular phone number, though that usually costs money or uses credits from a paid plan.
Key Takeaways
- Computer calls require internet-based software like Skype, Zoom, Google Meet, or Discord, plus a working microphone and speakers.
- Both people need the same app installed, or one person can join through a web link without installing anything.
- Video calls work the same way as voice calls—just make sure your camera is plugged in or enabled before you start.
- Calling someone's regular phone number from your computer usually requires a paid plan or prepaid credits.
- Test your microphone and speakers before your first call to avoid awkward silence or feedback.
Setting up your microphone and speakers
Before you make your first call, check that your computer can hear you and you can hear others. Most laptops have a built-in microphone above the screen and speakers on the sides or bottom. Desktop computers usually need separate speakers plugged into the audio jack (the one that looks like a headphone symbol), and a microphone plugged into the microphone jack (usually labeled with a microphone icon).
Open the calling app you plan to use and look for a Settings or Preferences menu. Find the Audio or Sound section and select your microphone from the list. Speak a few words and watch the volume meter—it should show a green bar that moves when you talk. If nothing moves, your microphone isn't working. Try unplugging and replugging it, or restart the app. For speakers, play a test sound and adjust the volume slider until you can hear it clearly without distortion.
If you use headphones instead of speakers, plug them in before opening the app. Headphones prevent feedback (that squealing sound) and let you hear better in noisy rooms. Most calling apps will automatically detect headphones and switch to them.
Finding and calling a contact
Each calling app stores contacts differently. In Skype, click the Contacts tab on the left side and look for the person's name. In Zoom, you can call someone if they're in your contact list or if you have their meeting ID. Google Meet lets you call anyone with a Google account if you know their email address. Discord works only if you're both in the same server or are direct friends in the app.
Once you find the contact, look for a phone icon or call button next to their name. Click it. The app will dial and show "Calling..." on your screen. The other person will see an incoming call notification and can choose to answer or decline. Wait for them to pick up—this usually takes a few seconds, but can take longer if they're away from their computer.
If the person doesn't answer after 30 seconds to a minute, the call will end automatically. You can try again, or send them a message asking if they're available. Some apps let you leave a voice message if the person doesn't answer, similar to voicemail on a phone.
Making a video call instead of voice-only
A video call works exactly like a voice call, except you're also sending your camera feed. Before you start, make sure your camera is plugged in (for desktop computers) or enabled (for laptops). Most laptops have a camera built into the top of the screen. Check that nothing is blocking the lens and that the lighting in your room is decent—sit facing a window or lamp so the camera can see your face clearly.
When you click the call button, look for a video icon next to it. Click that instead of the phone icon. Your camera will turn on and show a preview of what the other person will see. If you don't see a preview, your camera isn't working—check that it's plugged in and that the app has permission to use it. On Windows, go to Settings > Privacy > Camera and make sure the app is turned on. On Mac, go to System Preferences > Security & Privacy > Camera.
Once the other person answers, you'll see their video on your screen and they'll see yours. You can usually switch between video and voice-only by clicking a camera icon during the call if you want to turn your camera off.
Calling a regular phone number from your computer
Some apps let you call someone's regular cell phone or landline number, not just other computer users. Skype, Google Voice, and Zoom all offer this, but it's not free. You'll need to buy credits or pay a monthly subscription. The cost varies by app and by where you're calling—calling someone in the same country is usually cheaper than international calls.
To set this up, open the app and look for a Calls or Dialer section. You'll see a keypad where you can type a phone number. Enter the number with the country code if you're calling outside your country (for example, +1 for the United States). Click the call button and wait for the person to answer on their phone. From their end, it will look like a regular phone call—they won't need any special app.
Check your app's pricing page before you make the call so you know what it will cost. Some apps charge per minute, others charge a flat monthly rate for unlimited calls to certain countries. If you only call one or two people occasionally, pay-as-you-go credits are usually cheaper than a monthly plan.
Troubleshooting common call problems
If the other person can't hear you, your microphone isn't working or is muted. Look for a microphone icon on your screen during the call—if it has a line through it, click it to unmute. If it's not muted, go back to Settings and check that you selected the right microphone. Restart the app and try again.
If you can't hear the other person, check your speaker volume. Look for a speaker icon on your screen or in the app's settings. If the volume is turned up but you still hear nothing, try unplugging and replugging your speakers, or switch to headphones. If you're using a laptop, make sure the volume isn't muted at the keyboard level—some laptops have a mute button or a volume key you can press.
If the call keeps dropping or freezing, your internet connection is too slow or unstable. Move closer to your Wi-Fi router, or plug your computer into the router with an ethernet cable for a faster, more stable connection. Close other apps and browser tabs that might be using bandwidth. If the problem continues, restart your router by unplugging it for 10 seconds and plugging it back in.
If the other person's video won't load, ask them to turn their camera off and back on. If that doesn't work, they should restart the app. Sometimes a poor internet connection on their end causes video to freeze or not load at all—they may need to move closer to their router or close other apps.
Choosing the right app for your needs
Different apps work better for different situations. Skype is good for one-on-one calls with friends and family because it's straightforward and works on almost any device. Zoom is built for group meetings and video conferences—it handles large groups well and lets people join through a link without installing anything. Google Meet is free for up to 24 hours of group calls and works well if everyone has a Google account. Discord is designed for gaming communities and group chat but also handles calls well.
If you're calling someone who doesn't use computers much, Skype is the safest choice because it's been around the longest and most people have heard of it. If you need to call a regular phone number, Skype or Google Voice are your best options. If you're setting up a meeting with a group, Zoom or Google Meet are easier because people can join through a link without creating an account first.
Most of these apps are free for basic calling. You only pay if you want to call regular phone numbers or if you need features like recording or large group meetings. Start with whichever app your friends and family already use—that's always the easiest choice.
Frequently Asked Questions
Do I need to pay to make a computer call?
No. Calling another person on the same app is always free as long as you both have internet. You only pay if you want to call someone's regular phone number, and even then, only if the app offers that feature. Most apps have free plans for voice and video calls between computer users.
What if the person I want to call doesn't have the same app?
Some apps let you send a link that the other person can click to join without installing anything. Zoom and Google Meet work this way—you can call someone and they join through their web browser. If the app doesn't support that, you'll need to ask the person to install it first, or use a different app that you both have.
Can I call someone on a computer from my phone?
Yes, if you install the same app on your phone. Most calling apps work on phones and computers the same way. read the app to your phone, sign in with the same account, and you can call the same contacts from either device.
Is a computer call as clear as a regular phone call?
Usually yes, but it depends on your internet speed. A fast, stable internet connection gives you call quality as good as or better than a phone call. A slow or unstable connection can cause choppy audio or dropped calls. If you have problems, try moving closer to your Wi-Fi router or plugging in an ethernet cable.
What should I do if my camera won't turn on?
First, check that your camera is plugged in (desktop) or not blocked by anything (laptop). Then restart the app. If it still won't work, go to your computer's privacy settings and make sure the app has permission to use the camera. On Windows, that's Settings > Privacy > Camera. On Mac, it's System Preferences > Security & Privacy > Camera. Restart the app after you change the permission.
