The key feature of Flexisip is its scalability. As your communication needs grow, Flexisip expands to handle larger loads. This ensures that your software can keep up with your business needs and you're not left behind with outdated technology. The modular design provides flexibility and adaptability, allowing you to customize it according to your specific requirements.

Another significant advantage of Flexisip is its ability to deliver incoming SIP calls or text messages through its embedded push gateway. This function makes it suitable for mobile device platforms where receiving information requires push notifications, particularly when the app isn't running in the foreground. Thus, ensuring seamless communication without any interruptions.

With 120 GitHub stars and the latest commit on 2023-07-12 the project looks healthy.
