How can I use JsSIP with node

[Hamad Mohsen]

I'm trying to make a desktop application that supports SIP over WebSockets/Webrtc calls. However, I tested my code in the browser and it worked well, but when I used node js as a javascript runtime environment the following error occurs:

      if (!window.RTCPeerConnection) {
