Some of the Quickstart code wasn’t necessary for our IoT Podcast voicemail. The first section of code highlighted in the above image, for example, is used to identify callers for a customized greeting, but only if you know the caller’s number in advance. So I removed that. Additionally, there’s a section of code that reads aloud text for the voicemail greeting. We decided to record our own MP3 file for the greeting, so I modified that line as well. You can tweak the sample code however you’d like if you decide to create a similar project.

A professional voicemail greeting is a recorded message that welcomes callers to your business when no one is available to pick up the call. For a polished call experience, the greeting should reflect who the client is calling – whether a general business number, department, team, or individual – and when the customer can expect the call to be returned.
“Hey, there! This is [your name]. Please leave me a message with your name, number, and the reason you’re calling. If you also tell me [insert random fact] I’ll be sure to move you to the top of my call list. Have a great day!”
