According https://guillaume.nibert.fr/voip-asterisk-rpi-ipphone-project/ :

to connect a phone to the ip pbx, it must use an SIP Client
https://jssip.net/ : a js sip client

https://jssip.net/documentation/getting_started/
voilà le code pour appeler un téléphone via le IP PBX :

/ Create our JsSIP instance and run it:

var socket = new JsSIP.WebSocketInterface('wss:/sip.myhost.com');
var configuration = {
  sockets  : [ socket ],
  uri      : 'sip:alice@example.com',
  password : 'superpassword'
};

var ua = new JsSIP.UA(configuration); // A user agent reference available in th react context

ua.start(); // this would be in a partytown daemon worker

/**
 * and the code below is to call a 
 * phone via the ip pbx, providing 
 * the destination phone number 
 * - 
 * This code would be outside the 
 * webworker, and will get a ref on 
 * the user agent ( "ua", below ), from 
 * the React context
 **/
/ Register callbacks to desired call events
var eventHandlers = {
  'progress': function(e) {
    console.log('call is in progress');
  },
  'failed': function(e) {
    console.log('call failed with cause: '+ e.data.cause);
  },
  'ended': function(e) {
    console.log('call ended with cause: '+ e.data.cause);
  },
  'confirmed': function(e) {
    console.log('call confirmed');
  }
};

var options = {
  'eventHandlers'    : eventHandlers,
  'mediaConstraints' : { 'audio': true, 'video': true }
};

var session = ua.call('sip:bob@example.com', options);

Below, screenshotof the utube video showing the details of the infos conveyed by SIP protocol:

first notice the invitation field, it mentions a URI of the exact same format as the invitation link we can get from https://tryit.jssip.net/ :

Then notice the format of the second field : <phone number>@<ip address of the destination of the caller, could be wifi assigned ip for a phone, and there we ciould hhave a mobile app>
OK I HAVE ONE : WE IMPLEMENT An EXPO MOBILE APP TO CALL OVER IP

Adding SIP Client Extension in Asterisk installation

Ok, so if I give an SIP client to Asterisk,
then Asterisk can call any other SIP Client, eg a phone with a mobile app, with an SIP client (SIP client in the mobile app)
do that in the docker container, following those instructions: https://ixnfo.com/en/adding-sip-clients-to-asterisk.html

Omy, look at the configuration below :

To add the SIP client ot Asterisk, we have to edit a couple of Asterisk config files
theconfig says : if you ask the IP PBX to call the 6001 phone number, then the IP PBX will use the SIP Client extension, to call the 6001 number
so if like this, i redirectall calls to one same phone number (caller ID), there we would have someone taking all calls in
