5. Your voicemail will walk you through the setup process, including recording your personal greeting (the message that plays when you receive a call that goes to voicemail) and possibly your voice signature (your name, spoken by you into the recording).
Of the many things your phone can do, automatically recording a phone call is not one of them. Perhaps not including that feature is a security precaution for phone makers; it could be a potential liability issue. Regardless, from time to time, documenting a call is a useful thing to do, whether you’re conducting a phone interview or cataloging a customer service call.

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.
Voicemails don’t necessarily have to be monotonous or extremely jazzy or funky. What you’re looking for is a balance between the two. Whenever I call someone and their voicemail greeting is playing, it tells me a lot about who they are, as a person. Which is why, you’ve got to put a little bit of “you” when it comes to voicemail. And the best part about all of this is, since you couldn’t come to the phone, at least the callers are having a good time listening to the message.
