问题
Hi I need to implement something like SIP phone but with a 'classic' SIP without WebRTC.
Most JS libs focus on SIP over websockets and WebRTC, but in my infrastructure, I do not have WebSockets. There are libs like JsSIP even with support for WebSockets in Node.js.
Maybe I should solution is to use software like webrtc2sip? But I fill this is little overcomplicated.
Some better solution?
