Can I make a video call to the desktop application from the website?

Question

WebRTC

There is a task to make feedback for a custom video conferencing solution.
On page 3 of the video stream (sldp player), people outside the office can see and hear the meeting.
I want to stick a form with a chat and a video call button so that at any time any participant can ask a question or set up a video call in text.
On the side of the office, there is a projector window with a presentation on the entire wall, I want to order a chat program on some .net so that it hangs quietly all the time, and at the time of the chat a window appears on top of the presentation, and when you call, a window with video appears.
Is such an idea feasible? or does webrtc only work browser-to-browser?
Do I need an intermediate server or just forward the port and the stream from the browser will go to the program?
The whole magic is that the window pops up on top of the presentation and the speaker instantly sees the question. He is heard and seen, and if he asks to call, the program automatically receives the call.
I hope I explained clearly.

Answer 1

Yes, it is possible.
You can connect to FreeSwitch from webrtc, and you can also connect FreeSwitch to anything else. From ordinary phones to desktop sip phones. So in theory, you won't even need to write your own application. Take some kind of sip client and you can call up subscribers connected via webrtc from it.

Thank you for your reply!
I have Asterisk and 3cx, will they work or do I need a freeswitch?
