The Cognigy Click To Call SDK requires a browser that supports the WebRTC APIs: RTCPeerConnection, getUserMedia.

​
Web Browsers

WebRTC APIs are only available in secure contexts such as HTTPS or localhost. Ensure your application is served over HTTPS in production.

​
Mobile Browsers

Mobile browsers may have stricter autoplay policies for audio. Ensure that calls are initiated by a user gesture, for example, a button tap, to avoid audio playback issues.

Runtime Detection

Use checkWebRTCSupport() to verify browser compatibility at runtime before creating a client: 
import { checkWebRTCSupport } from '@cognigy/click-to-call-sdk';

const support = checkWebRTCSupport();
if (!support.supported) {
  console.error('Missing WebRTC features:', support.missing);
} else {
  console.log('WebRTC is fully supported');
}
