WebRTC (Web Real-Time Communication) is a technology that allows real-time voice, video, and data communication directly between browsers and devices. Most modern web browsers support WebRTC, enabling users to make voice and video calls, as well as transfer data without the need for additional plugins or software. Here’s a list of popular browsers that support WebRTC:
-
TURN and STUN servers are the two types of WebRTC servers. Each acronym refers to the transmission method the server uses to share data. And both of them are necessary for successful peer-to-peer connections. STUN stands for Session Traversal Utilities for NAT. STUN (Session Traversal Utilities for NAT) and TURN (Traversal Using Relays around NAT) are two protocols used in WebRTC and other real-time communication systems to facilitate connectivity through Network Address Translators (NATs) and firewalls. They serve different purposes and are often used together to ensure reliable communication. Here’s a breakdown of their differences:

- Understand Rocket.Chat’s VOIP Capabilities
Rocket.Chat supports VOIP through WebRTC, a technology that enables real-time voice and video communication in web browsers. The integration with WebRTC allows users to make voice and video calls directly within Rocket.Chat.
- Prerequisites
Rocket.Chat Installation: Ensure that Rocket.Chat is properly installed and configured. You can use Docker, a virtual machine, or a cloud service. WebRTC Support: WebRTC should be supported by the browser used by your clients.
Turn/ STUN Servers: For WebRTC to work reliably, especially in NAT and firewall environments, you’ll need TURN/STUN servers. 3. Setting Up TURN/STUN Servers TURN (Traversal Using Relays around NAT) and STUN (Session Traversal Utilities for NAT) servers are crucial for WebRTC to function properly. They help in establishing a connection between clients behind NATs and firewalls.
Use Public TURN/STUN Servers: You can use public TURN/STUN servers for testing, but for production, it’s recommended to set up your own. Example TURN/STUN Servers: STUN: stun.l.google.com:19302 TURN: You can use services like Coturn for setting up your TURN server. 4. Configuring Rocket.Chat for VOIP 4.1. Enable WebRTC in Rocket.Chat Log in to Rocket.Chat as an Administrator. Go to Admin Settings: Click on the gear icon in the top right corner and select "Administration." Navigate to WebRTC Settings: Go to Settings > VoIP (or WebRTC in some versions). Configure TURN/STUN Servers: Enter the URL for your TURN server and STUN server. Example configuration: STUN Server: stun:stun.l.google.com:19302 TURN Server: turn:your.turn.server:3478 TURN Username and Password: Provide the credentials if your TURN server requires authentication. Save Changes. 4.2. Check VOIP Settings Verify WebRTC Settings: Ensure that WebRTC is enabled and configured correctly in your Rocket.Chat instance. Test VOIP Functionality: Create a test channel and try initiating a call to ensure everything is working as expected. 5. Integrating with External VOIP Systems If you need to integrate Rocket.Chat with external VOIP systems (like SIP or other VOIP services), you might need additional tools or services. Some solutions include:
Using SIP Gateways: Tools like Asterisk or FreeSWITCH can bridge between SIP-based systems and WebRTC. Custom Integrations: Develop custom integrations using Rocket.Chat’s API and the VOIP provider’s API to facilitate communication. 6. Testing and Troubleshooting Test Different Browsers: Ensure WebRTC functionality across different browsers (Chrome, Firefox, Edge). Monitor Logs: Check Rocket.Chat logs for any errors related to VOIP and WebRTC. Network Configuration: Verify network configurations to ensure that WebRTC traffic can pass through. 7. Additional Considerations Security: Ensure that your TURN server is properly secured, and use HTTPS for WebRTC connections. Scalability: For large-scale deployments, consider load balancing and scaling solutions for TURN servers. By following these steps, you should be able to implement and configure VOIP in Rocket.Chat, enabling real-time voice and video communication for your users.
