Set up

Requirements

• .NET Framework
• A Twilio account - sign up
• ngrok

Twilio Account Settings

This application should give you a ready-made starting point for writing your own application. Before we begin, we need to collect all the config values we need to run the application:

Config Value	Description
Account Sid	Your primary Twilio account identifier - find this in the Console.
Auth Token	Used to authenticate - just like the above, you'll find this here.
Phone number	A Twilio phone number in E.164 format - you can get one here

Local development

After the above requirements have been met:

1. Clone this repository and cd into it

git clone https://github.com/TwilioDevEd/clicktocall-csharp.git
cd clicktocall-csharp

2. Set your configuration variables

copy ClickToCall.Web/Local.config.example ClickToCall.Web/Local.config

See Twilio Account Settings to locate the necessary environment variables.

3. Endpoints like https://<your-ngrok-subdomain>.ngrok.io/Call/Connect needs to be publicly accessible. We recommend using ngrok to solve this problem. Set up and run ngrok: ngrok http 1430 host-header="localhost:1430" (or use the ngrok Visual Studio extension)

4. Be sure to update the "PublicUrl" AppSetting in ClickToCall.Web/Local.config to match your ngrok URL (without a trailing slash).

5. Build the solution

6. Run the application

7. Navigate to https://<your-ngrok-subdomain>.ngrok.io

That's it!
