Workshop - Automating phone-calls and SMS

Many apps such as Twitter, Uber, Facebook, etc. use your phone number as your main/only user ID. Those apps require from you to validate your phone number as part of the registration/login process.

If you do the same or consider doing so, you can't afford downtime of your automated phone calls / SMS service and you must have full, production grade end2end tests constantly monitoring those flows.

This workshop will provide you with the background, the tools and basic hands-on experience to fully automate any kind of registration/login/MFA flow that involves SMS and/or automated phone calls using few simple, ready-to-use, open-source samples.

    Interesting content. Thanks Or for proposing. Just out of curiosity, would like to know if any of the tools used is open-sourced? Twilio etc. are popular paid services in my understanding. Mentioning the open-source brings most attendees more value and inclination to make use of the talk in a practical sense.

    As well as, the sample code used in the demo, do you plan to provide a public link?

    And in my understanding, a 90 minutes workshop would be more awesome on this content, what do you think?

      Hi Pooja!

      • The presentation uses 3 tools:
        • SMS reception API
        • Asterisk for the phone calls (Asterisk is an OSS)
        • Speech Recognition API.
      • The demos this session provides use Twilio as the SMS reception API and Google's Speech API. Both APIs can be replaced with open-source software and hardware for the SMS reception, however - as this is not as scaleable as using a 3rd party API - the examples I show use the paid versions in order to provide CI-grade solutions.
      • I'll be happy to add a couple of 'do it yourself, for free' slides :)
      • Asterisk and Selenium are the largest players in this presentation and they're both open-source.

      All the code samples I use in my demos are always open-sourced and public - it's an ideological thing :D
      The samples will be very similar to those I used in SeConf Berlin: https://github.com/orpolaczek/seconf-2017-demo

      I was wondering wether to suggest a 45 minute talk AND a full-day workshop or just a 90-mins workshop. We could definitely shoot for a 90-min workshop but I think it'll be more difficult to fit an actual 'hands-on' part in the 90-min version. What do you think?

        Thanks Or for the thoughtful and detailed answer. 

        Yes with context to 45 m or 90 min hands-on, we need to grill it a bit more. Suppose you plan to have hands-on, probably the contents could be shrunk and the key subtopics as quick start could be covered?

        One snippet for each sms, voice and speech recognition could be best. And to prevent delay (real workshop factors) we could probably give attendees to download and keep code ready and maybe it could be more of a demonstrating but attendees running them on their machine can do the magic called satisfaction of learning. How do you find it?

          Pooja - thank you for the comments.

          I agree. I've withdrawn the 480-mins proposal and updated this one to a 90-min workshop with a more detailed breakdown.

          Please let me know what you think :)
