If someone is listening to your voicemail greeting it's only because they intend to leave you a message. Don't make them listen to 3 minutes of rambling in order to do so. Plus, you're more likely to deliver a clean, professional read if you stick to shorter greetings. If more specific information is needed, direct callers to where they can find it on your website.
On the Greeting page there are two options. The standard option is to use the default iPhone voicemail message, but you can also record a custom message. If you already have a custom iPhone voicemail message recorded, tap Play to listen to it now. Otherwise tap Custom.

To recover a deleted message, tap Deleted Messages, tap the message, then tap Undelete.
When you receive a voicemail, a notification will alert you on Skype for Business apps, desktop phone, and email app. If the caller hangs-up before leaving a message, you will receive a Missed-Call Notification email with the caller information (if it was not blocked). What's it like for callers to leave messages? Depending on the users settings for Call Answering Rules Callers can hear a greeting, record a message (up to 5 minutes), and/or choose to be transferred to the target defined by the user.
