Teljs

Teljs is an open-source JavaScript library designed to simplify the integration of telephony features into web applications. It provides a lightweight and modular approach to handling voice calls, SMS messaging, and other communication functionalities directly within a browser environment. By leveraging the WebRTC (Web Real-Time Communication) standard, Teljs enables developers to implement real-time voice and video communication without requiring complex backend infrastructure.

The library is particularly useful for applications that require basic telephony capabilities, such as customer support systems, VoIP (Voice over IP) services, or interactive voice response (IVR) tools. Teljs abstracts many of the complexities associated with WebRTC, including signaling, media stream management, and peer connection handling. This allows developers to focus on building user interfaces and application logic rather than low-level networking details.

Key features of Teljs include support for initiating and receiving calls, handling call states (e.g., ringing, connected, disconnected), and managing audio and video streams. The library also integrates with popular telephony APIs, such as Twilio, making it easier to connect web applications to cloud-based telephony services. Additionally, Teljs offers event-driven programming, allowing developers to respond dynamically to changes in call status or media quality.

Teljs is released under an open-source license, encouraging community contributions and customization. It is designed to be extensible, enabling developers to add or modify functionality as needed. While primarily focused on web applications, its compatibility with WebRTC ensures cross-platform support across modern browsers.

For developers looking to incorporate telephony into their web projects, Teljs provides a practical and efficient solution, reducing the time and effort required to implement advanced communication features. Documentation and examples are typically available through its official repository or community resources, making it accessible for both beginners and experienced developers.
