Proxy Voice Calls Anonymously with Express

We're going to use a virtual number that connects two parties but is only usable for the duration of the current transaction, to avoid giving out our personal phone numbers to strangers. We'll rent a virtual number through Vonage CLI and associate it with an application to link multiple numbers to a single backend. Our Express server will have a single endpoint that returns an NCCO file containing instructions for the Vonage API when someone answers or makes a call, using the rented virtual number as the caller's identity. To use our proxy server, we'll create a Vonage Voice Application and link it to our virtual number, configuring our Glitch .env file with the required numbers in E.164 format.
