This Express application uses Twilio to connect incoming phone calls to other phone numbers based on where the caller lives. When a user dials in, the application looks up some information based upon their assumed location and triggers actions inside the application. The application is designed to automatically route customers to a regional office or direct callers to a survey after their interaction with customer service. In this sample application, the users' senators' offices are connected. The application uses Twilio's Node Helper Library to interact with the Twilio API and set up a Twilio account and the Express application itself. A webhook endpoint is created for the application to accept inbound calls, and the `action` attribute is used to redirect the call to another route when the first senator ends the call. The application also includes a thank-you message and an end to the call with `<Hangup>`. To run this sample app, you need to download the code and follow the README instructions on Github.
