Give The Caller Instructions: Instruct the callers what topics you want them to leave voicemails for, and what topics you want them to call back for during office hours.
To turn the message notification on and off, from the main menu, select 4 (Mailbox Options) and then press 1 (Notification Options). Now follow prompts to turn the notifications on or off. If the new message indicator remains on after you've listened to your new messages, try turning the notification off and on several times and end with it set to on. Check your messages and access your mailbox

Another great information you can put in your voicemail messages is to inform your prospects when you can reach out to them say the next morning or mid-afternoon and more so that they can be aware of when they can expect a call from you.
