What is a web dialer?

A browser-based dialer lets you make phone calls directly from a website. Unlike VoIP apps like Skype or Viber that require downloads, web dialing lets you call on the web the moment you open the website.

When you make a call, your voice travels over the internet to a gateway that connects to the traditional phone network (PSTN). The person you call receives a normal phone call on their landline or mobile. They don't need internet, a smartphone, or any app to answer.

This makes web dialers different from app-to-app calling services like WhatsApp or FaceTime, which only work when both people have the same app installed.


How to make a phone call from your browser

Making a call with HelloAirDial takes less than a minute:

  1. Go to helloairdial.com in Chrome, Safari, Firefox, or Edge
  2. Create a free account with just your email address
  3. Enter the phone number including the country code (e.g., +1 for US, +44 for UK)
  4. Click call and allow microphone access when prompted
  5. Start talking - the recipient answers like any normal phone call

The person you're calling doesn't need internet, an app, or any special equipment. Their phone simply rings.

How browser calling works

Browser calling relies on WebRTC (Web Real-Time Communication), an open-source protocol built into all modern browsers. Here's what happens when you place a call:

  1. Voice capture: Your microphone picks up your voice and converts it to digital data
  2. Encryption: The data is encrypted using SRTP (Secure Real-time Transport Protocol)
  3. Transmission: Encrypted packets travel over your internet connection to the calling service
  4. PSTN gateway: The service connects your call to traditional phone networks
  5. Delivery: The recipient's phone rings like any normal incoming call

This entire process happens in milliseconds. Because WebRTC is built into Chrome, Safari, Firefox, and Edge, there's nothing to download or install.

Is browser calling secure?

Yes. WebRTC has security built into the protocol:

  • SRTP encryption protects your voice data before it leaves your browser
  • DTLS key exchange prevents man-in-the-middle attacks
  • Browser permissions require your explicit consent before accessing your microphone

Your personal phone number is never automatically exposed to the person you call, which adds a layer of privacy compared to traditional calls.


When to make calls on the web

✈️ International calls without roaming: Connect to hotel wifi or local internet while traveling and call from any country at regular rates instead of paying roaming fees.

💼 Business outbound calls: Sales reps and support staff can make calls from any computer without setting up phone lines or installing software on each machine.

🏠 Remote work: Make professional calls from home, a coffee shop, or a coworking space without giving out your personal phone number.

🔒 Privacy: Keep your real phone number private when responding to classified ads, making initial business contact, or in any situation where you don't want to share personal details.

📱 No app clutter: Make calls when you need them without permanently installing another app on your phone.

Supported browsers and requirements

Browsers

HelloAirDial works on any modern browser with WebRTC support:

  • Chrome (recommended)
  • Safari
  • Firefox
  • Edge
  • Opera
  • Brave

Devices

  • Windows, macOS, Linux, ChromeOS
  • iOS (Safari)
  • Android (Chrome)

Internet connection

  • Minimum: 1 Mbps (basic calls)
  • Recommended: 3+ Mbps (HD audio)
  • What matters most: Connection stability, not raw speed. Aim for latency under 150ms.

For best quality, use 5GHz wifi instead of 2.4GHz, or a wired ethernet connection for important calls.

Troubleshooting common issues

No audio: Check that microphone permission is granted in your browser settings. Verify the correct input device is selected.

Choppy audio: Move closer to your router, switch to 5GHz wifi, or pause large downloads during your call.

Echo: Use headphones instead of speakers. Lower your speaker volume.

Call won't connect: Verify the number is in correct international format (+country code). Check if a VPN or firewall is blocking WebRTC.

For more help, see our microphone troubleshooting guide.


Limitations to consider

Requires internet

A web dialer only works when connected to the internet. If wifi goes out or you're somewhere without data, you can't make calls. Keep your regular phone service as a backup for emergencies.

No emergency calls

Web dialers cannot call emergency numbers (911, 999, 112). Always use a traditional phone for emergencies.

No native app

HelloAirDial runs in your browser rather than as a standalone app. You won't get push notifications for missed calls, but voicemails are forwarded to your email. You can add the site to your home screen for quick access.
