Simple express server to mock the UDM unifi talk config files sent to freeswitch

README.md

Run this script on another machine, and switch in /etc/freeswitch/autoload_configs/xml_curl.conf.xml the URL for binding=configuration. Then relanch unifi-talk, and the new configuration should be fetched by freeswitch.

const express = require('express');
const bodyParser = require('body-parser');

const app = express();

app.use(bodyParser.urlencoded({extended: true}));

app.use((req, res, next) => {

  next();

// For debug purpose

  req.method = 'POST';
  req.body = {
    key_value: req.params.confName
  };
  next('route');

// To get the original files to replace here : you can run on your UDM terminal : 
// curl -X POST -d "key_value=sofia.conf" http://127.0.0.1:3423
// curl -X POST -d "key_value=post_load_switch.conf" http://127.0.0.1:3423
// curl -X POST -d "key_value=acl.conf" http://127.0.0.1:3423
