Local development

This project is built using the ASP.NET MVC web framework.

1. First clone this repository and cd into its directory:

   git clone git@github.com:TwilioDevEd/ivr-phone-tree-csharp.git
   cd ivr-phone-tree-csharp
   

2. Build the solution.

3. Expose your application to the wider internet using ngrok. This step is important because the application won't work as expected if you run it through localhost.

To start using ngrok in our project you'll have execute to the following line in the command prompt.

ngrok http 1112 -host-header="localhost:1112"

Keep in mind that our endpoint is:

http://<your-ngrok-subdomain>.ngrok.io/ivr/welcome

Remember to update the Local.config file with the generated ngrok subdomain.

1. Configure Twilio to call your webhooks.

You will also need to configure Twilio to call your application when calls are received in your Twilio Number. The voice url should look something like this:

http://<your-ngrok-subdomain>.ngrok.io/ivr/welcome

Learn how to configure your Twilio phone number for Programmable Voice.
