    Build Round Robin Call Forwarding Using Twilio Studio & Functions Round Robin Routing Studio Functions

    One of the most common application workflows – regardless of the context – is round robin routing.

    You can build round robin routing in a straightforward way with programming logic. However, to run this logic, you need a web server which must be managed – introducing a whole new realm of responsibility. While for larger operations this isn’t a problem, mom and pop shops don’t want to take this on and it often puts this functionality out of reach.

    Now with the help of Twilio’s Runtime suite, including Twilio Studio and Functions, you can build your own round robin call forwarding application without worrying about your own web server. In this post, I’ll show you how to set up a serverless round robin call forwarding solution.


    In order to follow this tutorial, you will need:

    • A Twilio account and active number. If you don’t have an account, …

    How we built a COVID-19 volunteer support line for our local community using Twilio Studio How we built a COVID-19 volunteer support line for our local community using Twilio Studio

    Update 3/20/20: If you are building something like this to help out your community, please check whether the Twilio.org Impact Access Program can help you. We have expanded eligibility to include volunteer groups and companies working on communications for public benefit to support COVID-19 response.


    I am sure many of you saw posts from people setting up groups of Covid-19 volunteers on social media over the weekend. We did, and joined a group of volunteers coordinating how to support the vulnerable in our villages in Somerset, UK.

    Screenshot of a facebook message suggesting a volunteer network to support vulnerable people in a small village in Somerset, UK

    The volunteer group's first idea was to post leaflets through peoples doors with our own phone numbers as a point of contact, following the advice of Covid-19 Mutual Aid UK.

    “Bear in mind that whilst Facebook or WhatsApp are good organising platforms, they might not be the easiest way for vulnerable people in your area to find and contact your group. Those …

    Master Your Calendar with Twilio Studio and a Little Bit of Mathe-Magic Master your calendar with Twilio Studio and a little bit of Mathe-Magic

    We spend a lot of time sorting out future plans, and there are some people who seem to have their whole calendar in mind at a moment’s notice.

    Keep Your Christmas Party Organized with Some Twilio Magic christmas-party-organize.png

    If you have ever tried to keep over a hundred people organized for a Christmas party, you will already know how much of a nightmare it can be!

    Tarik Zawia and Adam King from Twilio’s London office decided to add a little Twilio Magic to make this year's event a success.

    Defining Christmas Party Organizational Challenges

    Tarik Zawia - Account Executive - EMEA

    Working for Twilio, I knew that communications could be used to help keep things on track. This winter, I decided to have some fun with Twilio to make our US Alumni Club annual London pub-crawl (co-hosted by Cornell, GW, and UChicago) a little more hi-tech than in previous years.

    So, as with most (highly important and serious) engineering projects, we started with a problem to solve...

    Advanced Schedules for Twilio Studio Schedule.png

    Recently, one of my customers asked me to design a scheduling function for them. Here were their requirements:

    • Both Studio Flows and Web Chat had to use the same function
    • The Function needed to handle holidays, as well as days with irregular hours of operation
    • The customer wanted to play a special message in the IVR during the holiday season. The scheduling function has to be versatile enough to know if it's holiday season or not
    • The customer will eventually operate in 12 different time zones, the function had to be market and time-zone aware
    • Functions v2 must be used, so they can include it in their CI/CD pipeline

    JSON file for the schedule

    Here is a JSON file that I came up with that will meet my customer's requirements:

      "holidays": {
        "12/25/2019": {
          "description": "Christmas"
      "partialDays": {
        "12/26/2019": {
          "begin": "10:00:00",
          "end": "14:00:00",
