– Thanks for calling. This is (name). Today is a Friday and I am working from our corporate office. If you need to reach me immediately, please call (number). Otherwise, please leave me a message and I’ll return your call as soon as possible.
I can't come to the phone now, so if, well, actually, I can come to the phone now, I mean, like, I'm at the phone now, recording this message, but I'm doing this now, while you're listening to it later, except for you I guess it's now, like, when you're listening to it ... now I'm confused ... leave a message and I'll explain later.

You might not be the kind of person who wants customers to go through long voicemails. If that sounds like you, here are a couple of short and sweet voicemail greetings that you can use to get your message across!
My 12 y/o niece put on her cell phone message, "Leave your name and number. If I love you, I'll call you back." Although not earth-shatteringly funny, it was cute the way she said it. In college my roomate was a cop, he told me that the worst things you can say on an answering machine were 1) telling them your name, 2) telling the caller your number, 3) and that you aren't at home. Well, here's what I did... Thats probably good advice for a home phone, but at the same time, I don't think it applies to a cell phone really. I used to have a longer message aimed at keeping people from leaving messages ... but I hate getting voicemails for the most part. One summer I had my little cousin start singing take me out to the ball game, I cut him off after a few lines, but it was just my version of satire against parents who have their kids sing, and it was pretty funny.
