01Hello this is [your name], I’m either on another call or away from my desk. Please leave your details, along with a short message and I’ll get back to you. This is created by individual staff for their specific number or extensions. It’s a great voicemail greeting for work when you are on another line or away from your desk.
I've assembled this list in mid-nineties from the messages that people were emailing around. As far as I know, the author of this list is unknown.

“Hi, you’ve reached [your name] at [your company]. I’m unavailable right now — probably helping [type of company] get [X results, e.g. ‘double their leads in 60 days,’ ‘hire the best and brightest engineers,’ ‘convert 40% more customers.’] Leave your name and number, and we’ll discuss how your company can see similar results.” “Hello, this is [your name] at [company]. Thanks for calling. Please leave your name, number, and reason you’d like to chat, and I’ll get to back to you ASAP.” “Hi, you’ve reached [name] at [company]. If you need a quick response, please shoot me an email at [insert email address] and I’ll be in touch by EOD tomorrow. If it’s not urgent, leave me a message with your name and number. Have a great day.” “Hey, this is [your name]. If you’re calling for [X reason], please [contact so-and-so] or [go to our website, send me an email]. For all other inquiries, leave your name and a brief message and I’ll call you back within [one, two, three] business day[s].” “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.”
If you’re out of the office, a voicemail greeting will essentially act as the first line of communication between you and clients or potential clients. So of course, this could be a great opportunity to add a hint of personality, while of course still remaining as professional as possible. That doesn’t mean you can’t have some fun with it!
