Build Your Own Voicemail With Node-RED and the Nexmo Voice API

You've built a simple voicemail service using Node-RED and Nexmo APIs that allows callers to leave messages, which are then sent to your email address as an attachment. The system uses a webhook endpoint to receive incoming calls, records the message, and sends it to you via email with a subject line including the caller's number. You can also log call events in the debug area for further analysis. This setup provides a convenient solution for personal or business use cases where voicemail services are not readily available or desired.
