On Android, a variety of apps can record a call directly, unless the phone manufacturer blocks it. On iPhone, recording phone calls is blocked, period. The apps that do exist to record a call—and there are quite a few—have a workaround, but it will usually cost you.
We have collected 10 of the best voicemail greetings for business applications that we could find. Our goal is to demystify this tricky form of communication, which we detail at the end of this post. But first, it will be useful to go over some general suggestions to keep in mind if you plan to write a voicemail greeting for your business.

Your phone system greeting is the first thing callers hear. Set the right tone from the very start with professional greetings.
Open the Phone app. Tap the Voicemail tab in the lower right-hand corner of the screen. If Visual Voicemail is not set up on your iPhone, you'll see a button that says, Set Up Now. Tap that button. Enter, then confirm a custom voicemail password. Tap Custom if you want to create your own custom greeting when someone reaches your voicemail box.
