Your voicemail is important. Keep in mind, this is essentially one of the first impressions the hiring manager will have from you. You need to make sure your voicemail is as professional as possible. Whether you are trying to be funny, trying to show off your singing abilities or shouting in the car with the windows down, chances are the hiring manager won’t be impressed. Go into a quiet room and record a simple, “Hi, you’ve reached Kim Costa. I’m sorry I missed your call, but if you please leave your name, number and a brief message I will get back to you as soon as I can. Thanks!” You really can’t go wrong with this. Trust me when I say that hiring managers probably don’t want to hear your high school’s fight song.
39. Thank you for calling. I apologize for missing your call. I’m busy right now, but if you leave your name, number and message, I will return your call as soon as possible.

The above section details types of phrasing to avoid; however, it doesn’t detail what users should NOT say on their greeting. Though this is a bit loaded, as there are hundreds of combinations of things one shouldn’t say, there are some key components users should ALWAYS avoid. a. Forget About Slang: You should strive to be as professional and welcoming as possible in your greeting. While this may steer you towards using slang, in an attempt to make callers comfortable, it’ll most likely work against you. As a professional, your demeanor, tone, and speech should be clear cut and well articulated. Using slang undercuts this and works against you. b. Don’t Even Think About Profanity: This is a no-brainer. Never, under any circumstances, curse in your greeting EVER! c. Keep Your Sentences Clean, Don’t Ramble: Introduce yourself and give your caller specific direction. Avoid long diatribes detailing tangent thoughts. Keep it simple and quick. d. Always Return Your Calls: It’s important for callers to feel they are valued. Nothing dissolves this quicker than a greeting that doesn’t stress this. For example, “I’ll call you when I can,” “If I don’t return your call, please call back”—these phrases are terrible and completely destroy any good will you may have with a caller.
Typically, most of these services are uniform—i.e. include the same tools and features (send a script, they record it in a tone you approve, they send it as a file, you supply any feedback, etc.); however, there are some services that go above and beyond. For example, VoiceOverPro, is a single voice professional who records 30 second voicemail messages based on users’ scripts. This is standard; however, users also have options like adding music, recording up to 60 seconds (or 150 words), rush, 2-day turnaround, and even same day delivery.
