Make voice call using node js - node.js

Question

I am using Both Java web server and node js(for chat)
Now I want to make voice call using Twilio`
I wrote code like this
var fs = require('fs');
var sslOptions = {};
var path = require('path');
var express = require('express');
var app = express();
var server = require('https').createServer(sslOptions, app);
const EventEmitter = require('events');
const myEE = new EventEmitter();
server.on("request", function (req, res) {
res.end("this is the response");
});
server.listen('8090', function(){
console.log("Secure Express server listening on port 8090");
});
var accountSid = 'AC***************************';
var authToken = "******************************";
var client = require('twilio')(accountSid, authToken);
var morgan = require('morgan');
var bodyParser = require('body-parser');
var twilio = require('twilio');
var VoiceResponse = twilio.twiml.VoiceResponse;
module.exports = server;
app.use(express.static(path.join(process.cwd(), 'public')));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({
extended: true,
}));
app.use(morgan('combined'));
app.get('/', function(request, response) {
response.render('index');
});
app.post('/call', function(request, response) {
var salesNumber = request.body.salesNumber;
var url = 'http://' + request.headers.host + '/outbound/' + encodeURIComponent(salesNumber);
var options = {
to: '+91*******',
from: '+17******',
url: url,
};
client.calls.create(options)
.then((message) => {
response.send({
message: 'Thank you! We will be calling you shortly.',
});
})
.catch((error) => {
console.log('errot');
// console.log(error);
response.status(500).send('error');
});
});
app.post('/outbound/:salesNumber', function(request, response) {
var salesNumber = request.params.salesNumber;
var twimlResponse = new VoiceResponse();
twimlResponse.say('Thanks for contacting our sales department. Our ' +
'next available representative will take your call. ',
{ voice: 'alice' });
twimlResponse.dial(salesNumber);
response.send(twimlResponse.toString());
});
I am trying to make an ajax call from one of my javascript files to an express route
$.ajax({ url: '/call',
method: 'POST',
dataType: 'application/json',
processData: false,
data: {
phoneNumber: '+91*******',
salesNumber:'+17******** '
}
}).done(function(data) {
// The JSON sent back from the server will contain a success message
alert(data.message);
}).fail(function(error) {
//alert('errot');
alert(JSON.stringify(error));
});
when I execute this ajax call
it's looking for Java server and return 404 error
How can I solve this issue
