We’re all familiar with this type of voicemail greeting. Simply put, a caller reaches you by dialing your number or extension directly. For an optimal personal voicemail greeting, be clear about who you are, the team you’re on, and when the caller can expect a callback. Unlike company and department voicemail greetings, you may not be able to configure a greeting for open and closed business hours. If that’s the case, use a general voicemail greeting that accommodates both scenarios.
Your voicemail greeting is the message your callers hear when they reach your voicemail. There are two types of voicemail greetings - Busy and No Answer. The Busy greeting is played when you are on another call and do not have call waiting, and the No Answer greeting is played when you do not answer the call.

Informal voicemail greetings are those that don’t adhere to the rules of professional and business voicemail greetings. Here, you are free to just leave a simple greeting, or use it to show your more witty side. This style of greetings can be used for both home and business if you like, depending on the type of caller you expect.
The bottom line is that a business’s situation is likely to change often and rapidly, each of which need a unique and applicable voicemail greeting to cover the circumstances and timeline. For example, callers shouldn’t reach a business-as-usual voicemail, and therefore expect a return call within the business day, if the subject they’re calling is out on vacation for two weeks. Such a lack of communication is a recipe to lose that caller’s trust and tarnish the brand’s reputation.
