Hello, you have reached the dental office of Dr. X. We are busy assisting a patient now, but will call you back as soon as possible. Please leave your name, reason for calling, and your number. If this is an urgent enquiry, please call 911. In this case, the dentist is giving a reason for not being available and they’re providing a way to prioritize the patients who need the most help. They’re also leaving an emergency number for the most severe of situations.
Extension mailboxes enable businesses to share a group of mailboxes, but route incoming calls to one main voicemail number. They include a primary mailbox and up to nine (9) additional boxes. Each has characteristics of standard voice mailboxes and must be activated by an authorized user before they can be used. Once activated, log in to the mailbox, change the PIN, record your greeting and your name.

If, on the other hand, your clients work with a number of team members, you might consider hiring a voiceover professional to record your greeting. While a recording with a voice actor is an extra expense, the result often outweighs the cost.
