Frequently asked questions

1

What are the prerequisites to use this server?

Node.js >= 18.0.0, a Twilio account with Account SID, API Key/Secret, and a Twilio phone number, plus an ngrok account with an auth token.

What environment variables are required?

`NGROK_AUTH_TOKEN` is required for callback handling; `NGROK_CUSTOM_DOMAIN` is optional.

Stop the existing endpoint first, use a different domain name, or start both endpoints with `--pooling-enabled` to load balance.
