When your business is closed for vacation or holidays, it’s imperative that you set appropriate expectations for a callback and to provide an alternative coverage option, if available. The following greeting accomplishes this succinctly.
"Hello, you've reached [name] at [company]. I'm unable to come to the phone right now. Leave your name and number, and I'll return your call as soon as I'm free. Thank you."

And I think if you just want to add like let's say you want three numbers instead of four, because that's the next pricing point is four numbers instead of two. You can add a number at any of these levels for just $4 a month. So if regardless of which level of Vumber you have and you just want an extra number over and above what your account allows for bucks gets you a free number or get you a $4 number, all right, back to the script. So that's the way Vumber works. You can press pound and it skips the rest of the message and goes right to the beep.
As greeting messages should reflect your mood and your personality, they must be recorded with utmost care and with the right choice of words. Here are a few examples which you can make use of while recording your own greeting messages.
