Technical Details and Troubleshooting
How Calls Reach Real Phones
Call Quality Tips
- 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
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.

Frequently Asked Questions
Can I make a phone call online without an app?
Yes. You can make a phone call online without downloading any app. Open HelloAirDial in Chrome, Safari, Firefox, or Edge, enter the number, allow microphone access, and press Call. Everything runs in your browser, no installation required.
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 from my device?
Yes. You can call any landline or mobile number from any device with a browser (computer, tablet, or phone). For a step-by-step guide focused on calling from a computer or laptop, see our guide on how to make a phone call from your computer or laptop.
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.
