Important note: In some states, such as California, it’s illegal to record calls or conversations without permission from all parties involved. If that’s the case, ask your call participants if it’s OK if you record the conversation before you start recording. Then, ask again once you do start recording—so you have their permission on record. Alternatively, if you state “I’m recording this call for [whatever purpose]” and your contact stays on the line, that’s OK as well.
The above eight rules of engagement for voicemail greetings may sound easy enough, but they’ll require some practice to get just right. Let’s look at some examples to provide some context in how to apply the rules to various types of greetings and situations.

Voicemail greetings are simple things, and in a business, they can seem unimportant. However, a voice mail greeting gets a lot of play with customers and associates—think of how often you are unable to take a phone call because you're on another line, away from your desk or out of the office.
If you create a call answering rule but don't specify an action, your caller will hear the following prompt: "You have reached the mailbox of . Please call back later. Goodbye." and the call will end.
