Adding real-time voice calling to your app has never been easier thanks to the powerful voice sdk from CometChat. Whether you’re building a social network, customer support portal, or multiplayer game, CometChat’s Voice SDK gives you everything you need to launch high-quality, low-latency voice calls in minutes—completely free during development.

With CometChat’s Voice SDK, you get:

• Ultra-low latency audio streams optimized for mobile and web
• Built-in network optimization that adapts to fluctuating bandwidth
• Group call support for up to 50 participants
• Cross-platform compatibility across iOS, Android, and JavaScript
• Optional call recording and screen sharing

Getting started is straightforward. First, install the Voice SDK npm package or native library in your project. Then configure your CometChat credentials and initialize the SDK in just a few lines of code:

import { CometChat } from "@cometchat-pro/voice-sdk";
CometChat.init(APP_ID, { region: "YOUR_REGION" });
CometChat.login(USER_ID, AUTH_KEY);

Once initialized, you can start a one-to-one or group voice call with a single function call. The SDK handles audio routing, echo cancellation, and dynamic quality adjustments automatically:

CometChat.startCall(
  CALL_RECEIVER_ID,
  CometChat.CALL_TYPE.VOICE
).then(call => {
  console.log("Voice call started:", call);
}).catch(error => {
  console.error("Call failed:", error);
});

And because the Voice SDK is built on top of CometChat’s global edge network, you’ll enjoy rock-solid uptime and enterprise-grade security out of the box. No servers to manage, no scaling headaches—just crystal-clear voice calls that delight your users.
