Building A Salesforce Powered Call Center with Flybase and Twilio

In the world of telephony, an automated call distribution (ACD) system, is a system that distributes incoming calls to a specific group of agents based on the customer’s selection, customer’s telephone number, selected incoming line to the system, or time of day the call was processed. We also call this a call center.

A couple years ago, Twilio’s Charles Oppenheimer built a demo of a Salesforce embeddable ACD using Twilio Client and Ruby.

Many thanks to Charles for sharing that demo. We have simply taken that demo and converted it to Node.js with a Flybase powered backend to handle the distribution of calls, rather than the original Ruby / Mongo system, the result is a cleaner call center that’s easy to modify and integrate into other CRMs.

  • Flybase.io as our backend, handling storing data, passing events and our call queues.
  • Twilio Client is WebRTC interface to Twilio. In our demo we are using the javascript library which gives us an API and connection to Twilio to receive the call within our Salesforce browser delivering the call via WebRTC. Twilio client also gives us the ability to control the call via our soft phone.
  • Heroku will be used as our webhost, but you can host your call center anywhere you’d like.
  • Salesforce Open CTI is an open API to allow third party CTI vendors to connect telephony channels into the Salesforce CRM interface. In our demo we use Open CTI to house our soft phone and drive the click to dial/text functionality. The demo requires no plugins or installed software thanks to the design of Open CTI. For more info see the developer guide.

The actual salesforce integration is optional, and you can easily insert your softphone into another CRM. Part 2 of this tutorial will actually use flybase to build a simple CRM with the softphone included as a widget.

Getting started#

You can find the full source code here.

First, let’s set up our node.js app.

Create package.json:

{ "name": "callcenter", "version": "0.0.1", "description": "Client ACD powered by Flybase, Twilio and Node.js", "main": "app.js", "repository": "https://github.com/flybaseio/callcenter", "scripts": { "test": "echo \"Error: no test specified\" && exit 1" }, "keywords": [ "twilio", "data mcfly", "flybase", "twilio", "sms" ], "author": "Roger Stringer", "license": "MIT", "dependencies": { "body-parser": "~1.4.2", "ejs": "~0.8.5", "express": "~3.4.8", "flybase": "1.7.2", "less-middleware": "~0.2.1-beta", "method-override": "~2.0.2", "moment": "~2.5.1", "node-buzz": "~1.1.0", "twilio": "~1.6.0" }, "engines": { "node": "0.12" } }

This will tell our call center what modules we want to install for our node app.

Now, we want to create our app.js file to handle all our backend work:

var express = require('express'); var bodyParser = require('body-parser'); var methodOverride = require('method-override'); var path = require('path'); var config = require( path.join(__dirname, 'app', 'config') ); var app = express(); app.set('views', path.join(__dirname, 'app', 'views')); app.engine('html', require('ejs').renderFile); app.set('view engine', 'html'); app.use(bodyParser.json()); app.use(bodyParser.urlencoded({ extended: true })); app.use(express.static( path.join(__dirname, 'app', 'public'))); var port = process.env.PORT || 5000; // set our port var twilio = require('twilio'); var client = twilio(config.twilio.sid, config.twilio.token); var flybase = require('flybase'); var callsRef = flybase.init(config.flybase.app_name, "calls", config.flybase.api_key); var agentsRef = flybase.init(config.flybase.app_name, "agents", config.flybase.api_key); var queueid = ''; var good2go = false; // backend routes client.queues.list(function(err, data) { var to_go = data.queues.length; data.queues.forEach(function(queue) { if( queue.friendlyName === config.twilio.queueName ){ queueid = queue.sid; console.log( "Queueid = #" + queueid + " for #" + config.twilio.queueName ); good2go = true; } to_go--; if( to_go == 0 ){ if( queueid === '' ){ client.queues.create({ friendlyName: config.twilio.queueName }, function(err, queue) { queueid = queue.sid; }); } } }); }); // listen for events via Flybase... // if an agent gets disconnected then we log them off... agentsRef.on('agent-removed', function (data) { var data = JSON.parse( data ); console.log( data.username + " has left the building"); update_agent(data.username,{ status: 'LoggedOut' }); }); // return number of agents with status set to Ready agentsRef.on('get-ready-agents', function (data) { var adNag = function() { agentsRef.where({"status": 'Ready'}).on('value',function( rec ){ console.log( rec.count() + ' agents are Ready' ); if( rec.count() ){ agentsRef.trigger('agents-ready', rec.count() ); }else{ agentsRef.trigger('agents-ready', "0" ); } }); }; setTimeout(adNag, 1500); }); // listen for outgoing calls app.post('/dial', function (req, res) { var phonenumber = req.param('PhoneNumber'); var dial_id = config.twilio.fromNumber; if( typeof req.param('CallerID') !== 'undefined' ){ var dial_id = req.param('CallerID'); } var twiml = new twilio.TwimlResponse(); twiml.dial(phonenumber, { callerId:dial_id });

var client_name = bestclient; }else{ console.log( 'no agent was found, adding caller to #', config.twilio.queueName ); var dialqueue = queuename; addtoq = 1; } var twiml = new twilio.TwimlResponse(); if( addtoq ){ twiml.say("Please wait for the next available agent",{ voice:'woman' }).enqueue(config.twilio.queueName); }else{ twiml.dial({ 'timeout':'10', 'action':'/handledialcallstatus', 'callerId':callerid }, function(node) { this.client( client_name ); }); update_call(sid, { 'sid': sid, 'agent': client_name, 'status': 'ringing' }); } console.log("Response text for /voice post = #", twiml.toString()); res.writeHead(200, { 'Content-Type':'text/xml' });

}); }else{ twiml.hangup(); } console.log("Response text for /handledialcallstatus post = #", twiml.toString()); res.writeHead(200, { 'Content-Type':'text/xml' }); res.end( twiml.toString() ); }); // assign a twilio call token to the agent app.get('/token', function(req, res) { var client_name = "anonymous";

}); var server = app.listen(port, function() { console.log('Listening on port %d', server.address().port); }); // various functions ========================================================= // find the caller who's been `Ready` the longest function getlongestidle( callrouting, callback ){ if( callrouting ){ agentsRef.where({"status": "DeQueing"}).orderBy( {"readytime":-1} ).on('value').then(function( data ){ var agent = data.first().value();

}else{ // restart the check checking console.log("No callers found during queue poll #" + qsum); setTimeout(checkQueue, 3000); } }); }; setTimeout(checkQueue, 1500);

There’s a lot happening in this file. First, we require our various libraries and set up express, then we start our actual work.

You’ll notice we set up to Flybase references:

  • callsRef connects to our calls table and handles storing and retrieving information for incoming calls.
  • agentsRef conncts to our agents table and handles storing and retrieving information for agents.

The first backend task we handle is checking our twilio queues to retrieve the queueid or our call queue, or else create it if it doesn’t exist. We use this queue for storing incoming calls if there are no agents available in our call center, and they stay inside the queue until an agent is available.

Then we set up event listeners for two events:

  • agent-removed: when an agent logs out, then we update their user record to set them to not ready
  • get-ready-agents: just returns the number of agents currently set to Ready.

Then we have our actual URI end points:

  • /dial is a POST request which is handled by Twilio to make outgoing calls between the agent’s web browser and a phone number.
  • /voice is a POST request which handle incoming calls from phone numbers. This works by finding the agent that has had their status set to Ready for the longest time and assigning them to the call. If not agent is Ready then we place the caller in a queue and check it later.
  • /handdialcallstatus is a POST request that is called when a call finishes. It checks to see if the call was answered, not answered and depending on the DialCallStatus returned from Twilio, either place the caller back into the queue and take the agent out of Ready status, or hang up the call as it assumes the call is done.
  • /token is a GET request called via an ajax call on the frontend to assign a Twilio Client Capability Token to the agent while they are logged in
  • /getconfig is a GET request called also via ajax call from the client which returns the call center’s Flybase settings for the softphone to use in the frontend.
  • / is a GET request which displays the softphone, and assigns a name to the client based on the ?client query string.

We have three backbone functions that are used by the call center to handle various purposes:

  • getlongestidle is a function which checks for either an agent who’s status is set to Ready or DeQueing and returns that agent’s client name. In case of no agents being found, then we return false and it places the caller in their queue. DeQueing is a special status we’ll be setting at the end of our code as an agent becomes available.
  • update_agent will take the agent’s id and update their account in the Flybase database with new info, such as status updates when on a call, going offline, etc.
  • update_call is used in the same way as update_agent but for tracking calls.

Finally, we have the queue handling, this is a function called checkQueue, which is called 1.5 seconds after the app loads and then every 3 seconds, and performs a simple task:

  1. It enters into a loop to return all callers in the call queue
  2. If there are callers waiting to connect to agents, then it will look for the agent with their status set to Ready and who have been ready the longest by sorting by the readytime field.
  3. If an agent is Ready, then we set that agent’s status to DeQueing and connect the caller at the Front of the queue to that agent by calling our dqueueurl.
  4. If no agents are Ready, or no callers are in the queue, then we set a timeout to call the function again in 3 seconds and return to step 1 of the checkQueue loop.

We next want to create a folder called app and then inside that folder create a file called config.js:

module.exports = { // Twilio API keys twilio: { sid: "ACCOUNT-SID", token: "AUTH-TOKEN", appid: 'APP-ID', fromNumber : "TWILIO-NUMBER", welcome : "Thank you for calling.", hangup : false, queueName: "cnacd", dqueueurl:"http://yourwebsite.com/voice" }, // Flybase settings flybase: { api_key: "YOUR-API-KEY", app_name: "YOUR-FLYBASE-APP" } };

Update this file to contain your Twilio information, and your Flybase information.

For the Twilio information, you’ll need to create an Twiml App inside your Twilio account, create the app and have it POST to your call center website at /dial.

Also, create a new phone number inside Twilio and have that phone number POST to your call center website at /voice.

There is a variable called queueName which is the name of the queue you want your call center to use, and also a variable called dqueueurl, this is the URL to your website with /voice appended to it. You will need this for the dequeuing task as Twilio requires an absolute URL.

The softphone#

Inside the app folder, create two folders:

  1. views
  2. public

Now, inside public, create a file called index.html:

<!DOCTYPE html> <html> <head> <title>Twilio Softphone</title> <script type="text/javascript" src="https://static.twilio.com/libs/twiliojs/1.2/twilio.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.2.0/jquery.min.js"></script> <script src="https://na15.salesforce.com/support/api/31.0/interaction.js"></script> <script src="https://na15.salesforce.com/support/console/31.0/integration.js"></script> <script src="https://cdn.flybase.io/flybase.js"></script> <script type="text/javascript" src="/js/softphone.js"></script> <link rel="stylesheet" type="text/css" href="/css/dialer.css"> </head> <body> <div id="client_name" hidden="true"><%= client_name %></div> <div id="softphone" class="softphone"> <div id="agent-status-controls" class="clearfix"> <button class="agent-status ready">Ready</button> <button class="agent-status not-ready">Not Ready</button> <div class="agent-status active">Call In-Progress</div> </div><!-- /agent-status --> <div id="agent-status"> <p></p> </div> /agent-status --> <div class="divider"></div> <div id="number-entry"> <input placeholder="+1 (555) 555-5555"></input> <div class="incoming-call-status">Incoming Call</div> </div><!-- /number-entry --> <div id="dialer"> <div id="dialer-container"> <div class="numpad-container"> <div class="number" value="1">1</div><div class="number" value="2">2</div><div class="number" value="3">3</div><div class="number" value="4">4</div><div class="number" value="5">5</div><div class="number" value="6">6</div><div class="number" value="7">7</div><div class="number" value="8">8</div><div class="number" value="9">9</div><div class="number ast" value="*">&lowast;</div><div class="number" value="0">0</div><div class="number" value="#">#</div> </div> /numpad-container --> </div><!-- /dialer-container --> </div><!-- /dialer --> <div id="action-button-container"> <div id="action-buttons"> <button class="call">Call</button> <button class="answer">Answer</button> <button class="hangup">Hangup</button> <button class="mute">Mute</button><button class="hold">Hold</button><button class="unhold">UnHold</button> </div><!-- /action-buttons --> </div><!---action-button-containe --> <div id="call-data"> <h3>Caller info</h3> <ul class="name"><strong>Name: </strong><span class="caller-name"></span></ul> <ul class="phone_number"><strong>Number: </strong><span class="caller-number"></span></ul> <ul class="queue"><strong>Queue: </strong><span class="caller-queue"></span></ul> <ul class="message"><strong>Message: </strong><span class="caller-message"></span></ul> </div><!-- /call-data --> <div id="callerid-entry" style="display:<%= anycallerid %>"> <input placeholder="Change your callerid"></input> </div><!-- /number-entry --> <div id="team-status"> <div class="agents-status"><div class="agents-num">-</div>Agents</div> <div class="queues-status"><div class="queues-num">-</div>In-Queue</div> </div><!-- /team-status --> </div><!-- /softphone --> </body> </html>

This is our index file, which handles the output of our softphone for agents to use to accept and make calls.

Inside the public folder, create a folder called css and include the following two files:

dialer.css:

/* reset css */ article,aside,details,figcaption,figure,footer,header,hgroup,hr,menu,nav,section{display:block}a,hr{padding:0}abbr,address,article,aside,audio,b,blockquote,body,canvas,caption,cite,code,dd,del,details,dfn,div,dl,dt,em,fieldset,figcaption,figure,footer,form,h1,h2,h3,h4,h5,h6,header,hgroup,html,i,iframe,img,ins,kbd,label,legend,li,mark,menu,nav,object,ol,p,pre,q,samp,section,small,span,strong,sub,summary,sup,table,tbody,td,tfoot,th,thead,time,tr,ul,var,video{margin:0;padding:0;border:0;outline:0;font-size:100%;vertical-align:baseline;background:0 0}ins,mark{background-color:#ff9;color:#000}body{line-height:1}nav ul{list-style:none}blockquote,q{quotes:none}blockquote:after,blockquote:before,q:after,q:before{content:'';content:none}a{margin:0;font-size:100%;vertical-align:baseline;background:0 0}ins{text-decoration:none}mark{font-style:italic;font-weight:700}del{text-decoration:line-through}abbr[title],dfn[title]{border-bottom:1px dotted;cursor:help}table{border-collapse:collapse;border-spacing:0}hr{height:1px;border:0;border-top:1px solid #ccc;margin:1em 0}input,select{vertical-align:middle} .clearfix:before, .clearfix:after { content: " ";

Finally, we want to set up our softphone frontend code.

Create a folder inside public called js and add softphone.js:

This code is based on the original softphone.js code that Charles wrote, but I’ve added in Flybase queries directly to the frontend, and then set up event listeners.

Once we set up our softphone, we make three ajax calls to our backend:

  1. /getconfig to return our Flybase info and enable our agentsRef and callsRef variables. Once agentsRef returns isReady from Flybase, then we trigger a call to our startWebSocket function. isReady is a function that we can use with the Flybase client when we wait to until our connection has been established before performing other actions.
  2. /token which we pass the agent’s name and return a twilio capability token to let the agent make and receive calls
  3. /getcallerid to return the outgoing phone number for the call to use.

We use the startWebSocket function (which was based on the original) to set up three event listeners and to update the agent’s status as LogginIn, and the time they came online.

Later in the Twilio client code, we set the agent to Ready once their Twilio client connection has been setup:

Twilio.Device.ready(function (device) { sforce.interaction.cti.enableClickToDial(); sforce.interaction.cti.onClickToDial(startCall); var adNag = function() { SP.functions.ready(); }; setTimeout(adNag, 1500); });

We are going to listen for agents-ready and in-queue events from our backend to tell the softphone to update the display to show the number of agents who are set to Ready and waiting for a call and then number of callers who are in the queue waiting for an agent.

Finally, we’re going to use the onDisconnect event to fire off an agent-removed trigger when the agent goes offline for some reason, such as closing the browser, logging off, etc.

You’ll also notice a clone of our update_agent function in this file. One of the nice things about using Flybase is we can handle our database updates from either the frontend or the backend so that lets us do a lot that we couldn’t before.

The rest of the softphone.js file is actually the same as it was before, it talks to talks to the Twilio Client on incoming and outgoing calls and it either gets the client name from the ?client query string or it gets it from Salesforce, if you are displaying your softphone inside Salesforce.

You may also notice we make use of our new Promises functionality:

SP.functions.update_agent = function(client, data){ var d = new Date(); var date = d.toLocaleString(); SP.agentsRef.where({"client": client}).once('value').then(function( rec ){ var agent = rec.first().value(); for( var i in data ){ agent[i] = data[i]; } SP.agent = agent; SP.agentsRef.push(agent, function(resp) { console.log( "agent updated" ); }); }, function(err){ data.client = client; SP.agent = data; SP.agentsRef.push(data, function(resp) { console.log( "agent inserted" ); }); }); } SP.functions.update_agent = function(client, data){ var d = new Date(); var date = d.toLocaleString(); SP.agentsRef.where({"client": client}).once('value').then(function( rec ){ var agent = rec.first().value(); for( var i in data ){ agent[i] = data[i]; } SP.agent = agent; SP.agentsRef.push(agent, function(resp) { console.log( "agent updated" ); }); }, function(err){ data.client = client; SP.agent = data; SP.agentsRef.push(data, function(resp) { console.log( "agent inserted" ); }); }); }

In update_agent, we use promises to either return an existing agent record so we can update or else we create a band new record.

Deploying to Heroku (optional)#

This step is optional, and you can deploy anywhere you like.

You’ll want a Heroku account and also to have the Heroku toolbelt installed.

Create a file called Procfile and include:

web: node app.js

Now, run the following:

  1. git init
  2. heroku login to log into Heroku.
  3. heroku create to create the application within Heroku.
  4. git add --all . to add all of your new files to the repo.
  5. git commit -am 'first commit' to store the files inside the repo.
  6. git push heroku master to push your git repository to Heroku.
  7. heroku open to open your browser at your new, custom URL.

Call center is now working, you can add ?client=ANYNAMEYOUWANT to the end of the URL and it will set you up as the agent.

Configuring Salesforce (optional)#

This step is optional, the call center works without sales force and in part 2, we’ll build a basic CRM that you can integrate this into as well.

This part is actually pretty simple. First, create a file called TwilioAdapter.xml:

<?xml version="1.0" encoding="UTF-8" ?> <callCenter> <section sortOrder="0" name="reqGeneralInfo" label="General Information"> <item sortOrder="0" name="reqInternalName" label="InternalName">DemoAdapter</item> <item sortOrder="1" name="reqDisplayName" label="Display Name">Demo Call Center Adapter</item> <item sortOrder="2" name="reqAdapterUrl" label="CTI Adapter URL">http://YOURWEBSITE.com</item> <item sortOrder="3" name="reqUseApi" label="Use CTI API">true</item> <item sortOrder="4" name="reqSoftphoneHeight" label="Softphone Height">400</item> <item sortOrder="5" name="reqSoftphoneWidth" label="Softphone Width">300</item> </section> <section sortOrder="1" name="reqDialingOptions" label="Dialing Options"> <item sortOrder="0" name="reqOutsidePrefix" label="Outside Prefix">9</item> <item sortOrder="1" name="reqLongDistPrefix" label="Long Distance Prefix">1</item> <item sortOrder="2" name="reqInternationalPrefix" label="International Prefix">01</item> </section> </callCenter>

Change the appropriate info to point to your website, then follow these steps:

  1. Go to Call Centers > Create
    • Import a call center config included, TwilioAdapter.xml – after import, change the parameter CTI Adapter URL to the Heroku URL created in the first steps https:/<insert yourherokuappurl
    • add yourself to the call center under “Manage Call Center users” > Add more users > (find)
  2. You should now see a CTI adapter under the Contact tabs. However, you want to use the Service Cloud Console for all cti calls (which prevens browser refreshes that would hang up calls)
  3. To create a service cloud console
    • Setup > Create > Apps > New
    • Choose “Console” for type of app
    • give it a name, such as “Twilio ACD”
    • Accept default for logo
    • For tabs, add some tabs to your Service Cloud Console, such as Contacts, Cases
    • accept default for step5 “choose how records display”
    • Set visibility to all (for dev orgs)
    • You’ve now created an app! You will see you’r console in the App dropdown, for example “Twilio ACD”
  4. Configuring screenpops
    • you can configure screenpop response, such as to pop the search screen, in Setup > Call Centers > (your call center) -> Softphone Layout.

These steps were borrowed from Charles’ original post as they haven’t changed.

Finishing up#

Now you’ve got a working real-time call center ACD system that can be used stand alone (as a lone softphone), in a CRM such as Salesforce, or a CRM built entirely around it which we’ll do in the next post.

If you’re familiar at all with the original client-acd then not much has changed, other than being rewritten in node and using Flybase as the backend / signal system, and that was the plan with this post as I wanted to demonstrate how Flybase can be used within a call center and this one has always been a go to for various projects.

Just a reminder, you can find the full source code here.
