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.
Some research has shown that each time you leave a message, the chances of a callback go up about ten percent! Here’s how it works out: 1st voicemail = 11% callback rate. 2nd voicemail = 22% callback rate. 3rd voicemail = 33% callback rate. According to Zoominfo, the average callback rate after one call is just 4.8%.

Your voicemail message should ideally answer all of the following requirements: Brief -- nothing bores callers as much (or makes them hang up as often) as long voicemail messages; Informative -- if it's your professional voicemail, say your name, business, and if necessary, department. Let your callers know when to expect a return call
