Click to Call is built on standards-based real-time voice technology and runs in modern web browsers on phones, tablets, and computers. Visitors do not need to install anything.

​

Supported browsers

The widget is officially supported on the latest stable release of:

• Google Chrome
• Microsoft Edge
• Mozilla Firefox
• Safari

Both desktop and mobile versions of these browsers are covered. Older releases may work but are not officially tested.

​

Supported operating systems

• Mobile — iOS and iPadOS on iPhone and iPad, Android on phones and tablets
• Desktop — macOS, Windows, and Linux

On iOS and iPadOS, every browser is built on Safari’s engine and therefore behaves identically for voice calls.

​

Requirements for your website

If you embed the widget on your own site, the page must be served over a secure connection. This is a rule enforced by every modern browser for any feature that accesses a microphone — not something specific to Click to Call. If you share the widget as a direct link instead of embedding it, no setup on your side is required.

​

Microphone access

When a visitor starts their first call, their browser asks permission to use the microphone. Granting it is a one-time action per browser and site. If the visitor declines, the widget clearly explains how to re-enable access from their browser settings. Some devices also restrict microphone access at the operating system level — managed phones, corporate laptops — in which case the visitor must adjust their system privacy settings to allow the browser to use the microphone.
