Avoid background noise. Whether you have music playing in your office, or you’re sitting in a coffee shop, background noise can make it difficult for your customers to understand your greeting. Limit the noise around you when you leave your voicemail greeting.
One of the things to remember before recording your business voicemail greetings is to identify your pain points. This will help you to state more clearly for your clients in leaving enough context when leaving a voicemail.

I have a confession to make: I haven’t recorded a new voicemail greeting since 2014. In the past four years, I (hopefully) have become more articulate, poised, and self-assured. But hear my voicemail recording, and you’d think I was still new to the work world, a little unsure of myself — and probably not an authority. Obviously I need toupdate it. And if you haven’t changed your voicemail greeting in over a year, you’re likely in the same boat. After all, a professional voicemail recording boosts your credibility, makes you seem more competent, and encourages whoever’s listening to it to continue the relationship. A relatively unprofessional one — like mine, for instance — does the opposite: It encourages prospects, recruiters, and potential connections to run in the other direction. With that in mind, I’ve written 18 unique voicemail greetings for every situation. Pick your favorite, practice a few times, then record your new voicemail.
Company-level calls are usually directed to your general business number. There are occasions when everyone in the office is tied up and unable to pick up calls. It’s important to gather information about the reason for the call so that the right person or team can call them back. These greetings ensure that customers do not feel neglected while also providing assurance that their call will be attended to as soon as possible.
