Context does matter here. If the caller would reasonably expect you to answer the phone (such as if they were calling a store or other place of business), an apology for not being able to get to the phone makes the most sense.
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.

These are all key areas for clear English Pronunciation. When recordings a voicemail greeting like the one in our sample, it’s essential to “put your best foot forward” (this means to give the best impression possible, or to try your very best). It’s the first impression many people will get of you.
