Be honest...you've been fooled by this one before, haven't you? It goes like this: riiiing, riiing, riiiing "Hey." "Hi, it's Juli what's up?" "Oh. I'm not here right now, leave me a message after the beep". There is actually very little I find more irritating than this voicemail, especially for business. Why do you want to fake out a business opportunity? This voicemail leaves callers feeling embarrassed and you looking foolish.
It is really important to strike a balance between coming off as too cold, conservative and impersonal with making your message too out there, long or eccentric. If you can create something memorable, it will help engage a caller, or potential client. Go too far off the deep end, and you’ll scare them away

@umbra21 - It's not jokes that annoys me so much as someone who leaves a message ten minutes long, particularly when you have to wait out the whole thing before you can leave your voicemail.
Most people screen their phone calls and often avoid answering unknown numbers. If you’re applying for new positions, you should try to view each unexpected call as an exciting opportunity! In the event that you simply can’t pick up the phone, you’ll want a polished voicemail greeting to let the caller know they’ve reached the right person.
