I think it’s a sad reality that most organizations use a telephone system to screen and triage phone calls before transferring the call to the appropriate person – forcing an electronic interaction that isn’t always customer friendly.
If you have an assistant, include their name and contact information in your greeting. If you have a hard time delegating tasks, this is an excellent way to start building it into your processes.

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.
