Practice makes perfect, and the same applies to reading and making your business voicemail calls. Before making those calls, give the call agents or representatives of your company time to rehearse. Let them go through the script a lot, so they’re familiar with the words. With enough time to practice, your call representatives can also make their own notes on the scripts to be guided and to avoid any monotony.

When you’re using the traditional voicemail system, your carrier dictates some messages you’re going to store in your voicemail box. But with a virtual system, you can store and retrieve messages whenever you want. The cloud also allows you to convert the voicemail audio files and texts and send them via email to relevant departments for further screening.
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.
