Look Who's Talking
- 1. Look Who’s Talking Pablo Cantero @pablocantero http://pablocantero.com 28° GURU-SP - 09/03/2013
- 2. Why I started with it?
- 3. We had a problem We needed a phone support 24x7 in case the website becomes unavailable and other possible urgent issues.
- 6. Solution We decided to use a Communication as a Service (CaaS) to register a fixed phone number in Brazil, which receives a call and redirects it to the developer on duty cellphone.
- 8. Why Twilio? • No Contracts • Pay as you go • Simple and well documented API
- 9. Brazilian pricing • To receive a call = 1¢/minute • To make a call = 33¢/minute • To send a text: starts at =1.2¢/message • Fixed brazilian number = 3$/month • Fixed american number = 1$/month
- 12. Plantão Elo7
- 13. Call me maybe WebRTC
- 15. account_sid = ENV["TWILIO_ACCOUNT_SID"] auth_token = ENV["TWILIO_AUTH_TOKEN"] twiml_app_sid = ENV["TWILIO_TWIML_APP"] capability = Twilio::Util::Capability.new account_sid, auth_token capability.allow_client_outgoing twiml_app_sid token = capability.generate
- 16. <ul id="user-‐list" data-‐token="<%= token %>"> <% @users.each do |user| %> <li> <%= user.name %> -‐ <a href="#" rel="phone-‐number"> <%= user.name %> </a> </li> <% end %> </ul>
- 17. <ul id="user-‐list" data-‐token="eyJ0..."> <li> Pablo Cantero <a href="#" rel="phone-‐number"> +551199... </a> </li> </ul>
- 19. $ -‐> Twilio.Device.setup $("#user-‐list").data "token" $("a[rel=phone-‐number]").on "click", (e) -‐> e.preventDefault() if Twilio.Device.status() != "ready" Twilio.Device.disconnectAll() return $this = $ e.target Twilio.Device.connect $this.text()
- 20. $(function(){ Twilio.Device.setup($("#user-‐list").data("token")); $("a[rel=phone-‐number]").on("click", function(e){ e.preventDefault(); if(Twilio.Device.status() !== "ready"){ Twilio.Device.disconnectAll(); return; } $this = $(e.target); Twilio.Device.connect($this.text()); }); });
- 21. Other examples
- 22. Twilio + Monit = Pingdom Mingdom https://gist.github.com/phstc/5044114
- 23. # /etc/monitrc check host localhost with address 127.0.0.1 if failed port 8080 with timeout 15 seconds then exec "ruby /usr/bin/notify-‐site-‐is-‐down.rb'"
- 24. # /usr/bin/notify-‐site-‐is-‐down.rb require "rubygems" require "twilio-‐ruby" account_sid = ENV["TWILIO_ACCOUNT_SID"] auth_token = ENV["TWILIO_AUTH_TOKEN"] @client = Twilio::REST::Client.new(account_sid, auth_token) @client.account.SMS.messages.create( from: "+5511…", to: "+5511…", body: "Houston we have a problem, the website is down." )
- 25. SMS Forwarding <Response> <Sms from="+5511.." to="+5511..."> Hello World </Sms> </Response>
- 26. Twimlets https://www.twilio.com/labs/twimlets Twimlets are tiny web applications that implement basic voice and text functionality. Think of them as "Widgets" in the web world.
- 27. Apps which talk • Alerts & Notifications • Rewards • Reminders • System administration • Sales Automation • Bike Sampa • Identity Verification • Security token • Support Roulette ;)
