Project description:
"I am building a web-based application whose core purpose is to let users place and receive voice calls directly in the browser. The back-end call engine must run on FreeSWITCH, while the front end can rely on standard WebRTC/JavaScript stacks that play nicely with it.

Here is what I need from you:

• Set up and configure FreeSWITCH (including any required SIP profiles, TLS certificates, and WebSocket modules) so it can handle secure, low-latency voice traffic.
• Develop the web app client: Build a web application framework with calling features
• Implement real-time call status updates—ringing, active, ended—through WebSocket events.
• Provide concise deployment documentation so I can reproduce the environment on a fresh Linux VPS.

I already have the server and DNS ready; you bring the code, configuration, and Freeswitch and Web Appc development expertise to glue it together. If you have previous FreeSWITCH + WebRTC examples, mention them so I can jump straight into testing." (client-provided description)
