While deciding on a greeting remember that while it is important to be friendly, do not try to be cute or overtly sweet. It is not necessary to state the obvious details. It may be a good idea to change your voicemail message as often as possible. Also if you are recording a message for a business organization, it is important to let the caller know how to skip the message that is playing. If it is possible then giving an alternate number where the caller can reach you is always a great idea. Given later in this article are some examples.
“Good afternoon. You have reached the office of [your name]. I will be out of the office beginning on [date] and will be returning on [date]. Please leave a brief message with your contact information, and I’ll be sure to get back to you as soon as I return on [date]. If this is an emergency or you need to speak with someone before I return, please contact [name of colleague/supervisor], [their job title], at [their phone number].”

Your business depends on customer engagement, and voicemail messages are a large part of that engagement. A voicemail is nothing more than a digital recording system, where messages are stored for you to retrieve later. Voicemail allows you to be able to connect with customers while you are away or during your off-hours, where they can drop off a message while you are gone. A voicemail greeting, on the other hand, refers to the message that your callers hear upon answering the phone.
