Before you even begin to draft and implement business voicemail greetings, your pain points need to be identified. For example, if you’re upset that clients aren’t leaving enough context on a voicemail, make sure you’re clearly stating what needs to be in the voicemail. If your clients are unfamiliar with how your business operates and keeps calling during off-hours, identify what time is best to call and say you’ll respond to messages first thing in the morning.
People may not want to give information about who lives in their home to unknown callers for a variety of reasons. This information may be used by telemarketers who could then ask for you by name when they call again, scammers who might do the same, or people who are not interested in your welfare. Women living alone for instance may use the “we” instead of “I” to suggest more people living in a house, and can even opt for using the machine generated message or computer generated “male voice” instead of their own voice to increase their security at home. For personal security reasons, you might want to avoid indication of children in the home, too, and you certainly shouldn’t mention that you’re on vacation.

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.
Typically, web-based services let you enter a special section in their online dashboards. From there, you find the file and tell the system to apply it to your voicemail box.
