A developer tool for testing SMS and Voice applications.

This is a monorepo that contains two Dev Phone packages:

• the Dev Phone plugin, which uses the Twilio CLI to deploy Twilio account resources and launch a local development server to host the Dev Phone UI
• The Dev Phone UI, the user interface for the Dev Phone. It is a react app that is tightly coupled with the CLI plugin

To use the Dev Phone, you'll need to first have an up-to-date installation of the Twilio CLI, as well as access to a spare Twilio phone number. That means that you'll need an upgraded Twilio account, not a trial account.

Once you've installed the Twilio CLI, you're ready to add the Dev Phone plugin with the following command:

twilio plugins:install @twilio-labs/plugin-dev-phone

Once it's installed, you can run the Dev Phone with the following command:

twilio dev-phone

Check out the Dev Phone documentation to learn more about installing and using the Dev Phone.

Notes for folks working on this plugin are in DEVELOPMENT.md.
