Understanding Online Calling

How VoIP Technology Works

When you make a telephone call online, you are using Voice over Internet Protocol (VoIP). Unlike traditional calls that travel over copper wires, VoIP converts your voice into digital packets and transmits them over the internet. HelloAirDial utilizes advanced WebRTC (Web Real-Time Communication) technology, which allows this process to happen directly inside your web browser without plugins or external apps. This means you can call a regular phone number (landline or mobile) from your computer or tablet, and the person on the other end picks up their phone just like a normal call.

Online International Call: How It Works

An online international call lets you dial any country directly from your browser. Select the destination country (or type its code like +44 or +91), enter the number in international format, and connect. Calls traverse secure WebRTC to HelloAirDial and then to global carriers on the PSTN - so the other party answers like a normal phone call without needing your app or internet.

App-to-App vs. Browser-to-Phone

It's important to distinguish between the two main types of online calls. App-to-App services like WhatsApp or Skype require both you and the recipient to have the same app installed and be online. Browser-to-Phone services like HelloAirDial allow you to call any phone number in the world. The recipient doesn't need internet, a smartphone, or any specific app to answer the call. They will receive a call on their handphone or landline just like any other call. This makes Browser-to-Phone calling ideal for reaching businesses, landlines, or older relatives who may not use messaging apps.

How to Make a Phone Call Online: Getting Started

Quick Start Guide

To make a telephone call online right now:

Open HelloAirDial Web Phone.
Select the country or type the international code (e.g., +1, +44, +91).
Enter the full number in E.164 format and grant microphone access.
Press Call to connect - your recipient answers on their normal phone.

What You Need

To get great results, make sure you have:

A modern browser (Chrome, Edge, Safari, or Firefox) with microphone permissions allowed.
A built‑in mic or USB headset (recommended for echo cancellation and noise suppression).
A stable internet connection with low jitter/packet loss (Wi‑Fi is fine; Ethernet is best).
Close bandwidth‑heavy apps (cloud backups, large downloads, video streaming) during calls.

International Dialing Format (E.164)

Enter numbers in international format so routing is unambiguous: +<country code><area code><number>. Examples:

US: +14155550123
UK: +442071838750
India: +919876543210

Use the country picker or type the country code (e.g., +1, +44, +91) and then the local number (no leading zeros).

Costs, Privacy, and Benefits

Cheap Online International Calls

One of the biggest advantages of making calls online is the cost. Traditional carriers often charge exorbitant roaming fees or per-minute rates for international calls (often $1.00-$3.00/min). Online calling services route traffic over the internet for most of the journey, bypassing expensive international lines. With HelloAirDial, you can make online international calls to popular destinations like India, China, the UK, and Mexico for mere cents per minute, often saving 90% compared to carrier rates.

Privacy and Caller ID

Making a call online adds a layer of privacy. When you use HelloAirDial, your personal phone number is not automatically exposed to the recipient. This is perfect for business inquiries, classified ads, or dating, where you might want to protect your personal contact details. You can preview transparent, per‑minute rates on the rates page before you dial. Where supported, you may verify and display a business caller ID.

Technical Details and Troubleshooting

How Calls Reach Real Phones

HelloAirDial uses WebRTC in your browser to securely send your voice to our infrastructure, which then bridges the call to the public telephone network (PSTN). In short: Your Browser → Secure WebRTC → HelloAirDial → Global Carriers → Recipient's Phone. This design delivers fast call setup, wide reach (landlines and mobiles), and HD audio where supported.

Call Quality Tips

Voice calls typically need ~100 kbps each way, but stability matters more than raw speed. For best results:

Use a wired or strong Wi‑Fi connection (5 GHz over 2.4 GHz when possible).
Keep latency under ~150 ms and jitter under ~30 ms; packet loss should be < 1%.
Plug in a USB headset to reduce echo and background noise.
Disable VPNs that aggressively proxy UDP traffic, or allow UDP for WebRTC.

Troubleshooting Common Issues

No audio both ways: Ensure microphone permission is allowed; select the right input device in your OS/browser.
They can't hear you: Mic muted at OS level, or privacy settings blocking input. Check your input meter.
Robot/laggy audio: Move closer to the router, switch to 5 GHz Wi‑Fi, or use Ethernet; close heavy downloads; if on VPN, allow UDP.
Echo/feedback: Use a headset; reduce your speaker volume.
DTMF (keypad tones) not working: Try in‑call keypad again; some IVRs require in‑band vs. RFC‑2833 - retry after call connects.

Safety and Compliance

Online calling is subject to local laws. Obtain consent before recording calls. Emergency calling (e.g., 911/112) may be limited or unavailable - use your local emergency services instead. Respect do‑not‑call rules and applicable regulations when placing business or marketing calls.

Frequently Asked Questions

Do I need a fast internet connection to make a call online?

A stable connection is more important than raw speed. A standard 4G/5G mobile connection or basic home Wi-Fi is sufficient for high-quality voice calls (requires about 100kbps).

Can I call a landline phone from my computer?

Yes! That is the primary benefit of HelloAirDial. You can use your computer, tablet, or smartphone to call any traditional landline or mobile phone number globally.

What happens if the recipient doesn't have internet?

It works perfectly. Since you are calling their phone number, they do not need internet access. Their phone will ring just like a standard incoming call.

Why does the browser ask for microphone access?

Browsers are designed to protect your privacy. They cannot listen to you without your explicit permission. You must click "Allow" so the website can transmit your voice during the call.

Can I use a VPN?

Yes, but some VPNs degrade real-time audio by blocking or proxying UDP. If you experience lag or choppiness, allow UDP or try without the VPN.

Can I dial IVR menus and extensions?

Yes. Use the in-call keypad to send DTMF tones for menu selections, conference bridges, or voicemail PINs.
