Advanced Call Forwarding with Java, Spark, and Twilio

Learn how to use Twilio to forward a series of phone calls to your state senators.

Local Development

This project is built using the Spark web framework.

To run the app locally, follow these steps:

1. Clone this repository and cd into it.

   git clone git@github.com:TwilioDevEd/call-forwarding-spark.git
   cd call-forwarding-spark

2. Copy the sample configuration file and edit it to match your database configuration.

   cp .env.example .env

3. Create application database: Make sure you have installed PostgreSQL. If on a Mac, I recommend Postgres.app.

   createdb call_forwarding

4. Execute the migrations.

   ./gradlew flywayMigrate

5. Expose your application to the internet using ngrok. In a separate terminal session, start ngrok with:

   ngrok http 9292

   Once you have started ngrok, update your TwiML application's voice URL setting to use your ngrok hostname. It will look something like this in your Twilio console:

   https://d06f533b.ngrok.io/callcongress/welcome
   

6. Start your development server:

   ./gradlew run

   Once ngrok is running, open up your browser and go to your ngrok URL.

Run the Tests

./gradlew test
