Web Dialer
HelloAirDial is a web-based dialer built on WebRTC, the open protocol that ships with Chrome, Safari, Firefox, and Edge. It connects you to any landline or mobile in over 200 countries straight from your browser. Whether you're a professional calling clients abroad or reaching family overseas, just enter a number and the call rings through like any normal phone call.
What is a Web Dialer?
A web dialer is a tool that lets you make phone calls directly from your web browser. Sometimes called an online phone dialer or browser dialer, it works like any phone dialer — you enter a number and call — except there is nothing to download or install. Web dialing happens entirely in your browser using WebRTC, the open protocol built into Chrome, Safari, Firefox, and Edge.
You'll see the term spelled a few ways: web dialler in UK English, or as one word, webdialer, in some software documentation. All of them mean the same thing.
- ✓ 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 — they don't need internet, a smartphone, or any app
- ✓ Works for landlines and mobiles in over 200 countries
- ✓ Unlike WhatsApp or FaceTime, the recipient doesn't need to have the same app installed

How Browser Calling Works
Browser calling relies on WebRTC (Web Real-Time Communication), an open protocol built into all modern browsers. Here is what happens when you place a call:
- Voice capture — your microphone converts your voice to digital data
- Encryption — data is encrypted using SRTP before leaving your browser
- Transmission — encrypted packets travel over your internet connection
- PSTN gateway — the service connects your call to traditional phone networks
- Delivery — the recipient's phone rings like any normal incoming call
If your call isn't connecting or you have no audio, most issues come down to microphone permissions. See our microphone troubleshooting guide for fixes.

HelloAirDial Web Dialer Features
Works on Any Browser, Any Device
Chrome, Safari, Firefox, and Edge on Windows, macOS, iOS, and Android are all supported. Use your laptop at home, your work computer, or your phone's browser while traveling. Your account works the same way across all devices.
Use Your Own Caller ID
Verify your own phone number to display it as your caller ID for a one-time $0.50 fee, or purchase a dedicated US or Canada virtual number. Alternatively, use the default public +1 number available to all users with no setup required.
Pay Only for Minutes Used
No monthly fees, subscriptions, or minimum commitments. Add credit when you need it, pay only for minutes used, and your balance never expires. Check rates for any country before calling.
Call Landlines and Mobiles in 200+ Countries
Reach any landline or mobile worldwide. Unlike app-to-app services, HelloAirDial connects to the standard telephone network so you can call banks, government offices, and organisations that don't have messaging apps. Rates start from $0.02 per minute.
Voicemail Forwarded to Email
When someone calls back the number you used as caller ID, they can leave a voicemail that is forwarded to your email so you never miss important responses.
Record Calls for Your Sales Team
Record calls directly from the browser dialer — useful for sales teams doing cold calling who need to review conversations, coach team members, or maintain records of client interactions.
Key Advantages of a Web Dialer
A web-based dialer fits a few common situations particularly well. Here's where the in-browser model pulls ahead of traditional desk phones, calling apps, and SIP softphones.
Online Stores & Support Teams
Take customer calls and follow up on orders straight from your desktop. No headset hardware, no separate phone line, and nothing for IT to set up before you can pick up the next call.
Client-Facing Professionals
Stay reachable for international clients on a reliable, professional line. The same business caller ID works across every device you sign into, whether it's your laptop at the office or a hotel browser while you call abroad.
Remote & Distributed Teams
Run the team's outbound calling from one browser-based platform. New hires get going in minutes with nothing to ship or install. For sales floors with heavier volume, a dedicated outbound dialer covers cold calling and campaigns.
Freelancers & Business Owners
Keep business calls separate from your personal mobile. You pick the caller ID, decide whether to record, and pay only for the minutes you actually use, with no subscription on top.

How to Choose a Web Dialer
Not every web dialer is built for the same job. A small sales team running a hundred outbound calls a day has different needs from someone making the occasional international call to family. Six things are worth checking before you commit.
Browser and device support
Confirm the dialer runs on Chrome, Safari, Firefox, and Edge across desktop and mobile. A web-based dialer that only works in one browser will trip you up the first time you try to call from a phone or a borrowed laptop.
Call quality
Look for WebRTC with the Opus codec. Round-trip latency under 150 ms generally sounds indistinguishable from a regular phone call. A public status page is a good signal that the provider takes uptime seriously.
Country coverage and rates
An online phone dialer is only as useful as the destinations it reaches. Check the per-minute rate to the countries you actually call before you sign up; the headline price is rarely the rate to the country you care about. Our rates page lists every destination.
Pricing model
Pay-as-you-go versus subscription. If you call irregularly, monthly fees waste money. If you're running a small sales team that calls all day, the math flips. Be honest about your usage before picking a plan.
Caller ID flexibility
Can you display a number people will recognise, or are you stuck with whatever the platform assigns? Look for the option to verify a number you already own, or to buy a virtual number in the country you're calling from.
No-download requirement
A real web dialer runs entirely in the browser. If it asks you to install an app or browser extension to make calls, it's a hybrid product, not a true web-based phone dialer. That matters most on locked-down work computers where you can't install software.
Limitations of a Web Dialer (and When to Use a Regular Phone)
Browser calling isn't the right tool for every situation. A few cases where a regular mobile or landline still wins:
You need a stable internet connection
A web dialer needs around 100 kbps up and down per active call. Most home and office connections clear that easily, but flaky hotel WiFi or a crowded conference network can drop call quality. If your connection is unreliable, a regular phone is more dependable.
Emergency services (911, 999, 112)
A web dialer is not a replacement for emergency calling. Without a fixed location tied to the line, dispatch can't route you to the correct local authority. Always use a regular mobile or landline for 911, 999, 112, or any emergency number.
Locked-down work laptops
Some corporate IT policies block microphone access at the browser level, or restrict WebRTC traffic on the network. If your work laptop won't prompt for mic permission, that's usually the cause. Check our microphone troubleshooting guide first; if the policy is the blocker, a personal device is the workaround.
Long calls on a phone's battery
A browser tab with an active call uses noticeably more battery than the native phone app on iOS and Android. For a short call, the difference is negligible. For an hour-long call on a phone that's already at 20 percent, the native dialer is the safer pick.

What is an online dialer?
