如何从nodejs调用SIP？

Question

I've tried about 20 libraries, but none of them can do the basic thing "make a call".

Hi my SIP operator does not support WebSockets and WebRTC. And all the data that have given me this:

username: +790434344334 pass: dsfsfdsff domain: sbc.megafon.ru two ports: 5060, 8080 Transport: UDP, TCP

is there any nodejs library in the world that is capable of doing this simple thing:

nodejs index.js:

import SipClient from 'super-node-sip-library-without-websockers'

const client = new SipClient({
  domain: "sbc.megafon.ru",
  username: "+790434344334",
  pass: "dsfsfdsff"
})

const callSession = client.call("911")

callSession.inputAudioStream // audio stream
callSession.outputAudioStream // audio stream

// play sound
const localMp3FileStream = require('./localAudioFileStream.js')
localMp3FileStream.pipe(callSession.outputAudioStream) // connect local audio file to output stream
    
// send sms
callSession.sms("Sms text")

In other words, i just need to receive a nodeReadableStream from the SIP network with the sound of the voice that the person speaks to the phone, as well as send a nodeWritableStream to the SIP network with the sounds that I want

Is it really impossible to make SIP calls with node js?

With this registration information, you can use a sip phone; among all possibilities you try linphone and make incoming/outgoing basic calls from/to your smartphone or any other.

It is not so simple, a full stack SIP with node JS is a big thing, I do not think that it is available. However a practical approach is to do a kind of proxying , you may try to find a proxy sip, on github the first one is
