twilio How to Build Call Forwarding Apps Using Twilio Studio




Forward Calls with Twilio Studio

Published on 2022-03-19

You can set up call forwarding with just one Studio Widget. Divert calls to your personal or business number and never miss a critical call again.

Before you get started, you'll need:

New to Twilio Studio? Before completing this tutorial, you should familiarize yourself with the mechanics of working with Studio by reviewing the Getting Started guide.
Create your Studio Flow

Youll start with a fresh Twilio Studio Flow. Log into your Twilio account and navigate to the Studio Dashboard, then select Create new Flow or tap the + icon to create a new Flow. You can name your Flow anything you like, for example, "Call Forwarding".
Youll notice that the Canvas comes with a Widget already in place: thats the Trigger Widget, which kicks off your Flow when the Trigger you specify occurs. In this case, the Trigger is going to be an Incoming Call.

Configure and Publish your Flow

This Flow only requires one Widget: the Connect Call To Widget. Drag one onto the Canvas, and connect the dot from the Incoming Call Trigger to the dot in the upper left corner of the new Widget. This creates a Transition from the Incoming Call Trigger to the Connect Call To Widget.
In the right sidebar, you'll see the Connect Call To Widget's Configuration Menu. Select Single Number from the Connect Call To dropdown, and enter the number youd like to forward your calls to. You can also specify a Caller ID, which is the number that will show up when the call gets forwarded to your number. In this example, you can you leave the default.
Your Canvas is now set up! Press Publish to update the Flow, and you're ready to move on.
Connect your Flow to a Twilio Phone Number

Once youre happy with your Flow and you've published all changes, you can connect it to a Twilio Number so people can start interacting with it.
Navigate to the Active Numbers section of the Twilio Console and click on the number youd like to connect to the Flow. (If you do not have any phone numbers, you can purchase one from the Console.)
After clicking on the number, you will see its configuration menu where you can connect the number to your Studio Flow.
To configure this number to trigger your Studio Flow from an Incoming Call, scroll down to the Voice & Fax section of the configuration menu. Under Configure With, select the dropdown option "Webhook, TwiML Bin, Function, Studio Flow, Proxy Service". Then, under A Call Comes In, select the dropdown option "Studio Flow". You'll see another dropdown menu appear where you can select the Studio Flow you'd like to connect to when a call comes in to this number.

Choose the Flow you'd like to connect the number to, and then press Save to save these changes. Your Flow is now connected to your Twilio number!

Now its time to test it out. Dial your Twilio number, and it should immediately connect you to the number you specified. Lean back, relax, and bask in the knowledge that you'll never miss an important phone call.
