"Voice mail has lost its appeal primarily because it's very much tied to the notion of the phone and your communication being tethered to a physical thing or a physical location," he says.
The above greeting is a professional voicemail script used by many growing and established businesses. It delivers the message quickly and efficiently, without wasting the caller’s time.

a standard greeting (as recorded by the administrator or other person), followed by the mailbox owner's name (as recorded by the owner), and then the fixed system prompt, "Begin speaking after the tone, then hang-up when you are finished or press any key for further options."
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.
