Recording your professional voicemail greeting can sometimes cause apprehension, especially if you have never done so before. You may find it helpful to go to a very private location when you are ready to record, and this can help ensure there is no background noise when you are finished. Take a few minutes to review the list you made earlier, and rehearse the greeting a few times if you are extremely nervous. While you are rehearsing, make sure your speech flows smoothly and you do not use filler words like "uh" or "um". Is Amazon actually giving you the best price? This little known plugin reveals the answer. Professional voicemail greetings should be pleasant in tone to encourage customers to call back later.
With Web- and mobile-based communications taking over as the dominant means of contact for many customers, voicemail is on its way out. Quite simply, consumers have found better ways to stay in touch.

Identify Yourself—I believe identifying yourself through your voicemail greeting shows respect to everyone who calls you. It allows your callers to confirm they have dialed the right number. When people don’t include their name in their greeting, it leaves me wondering if they have something to hide. I have seen this to be true far too often.
Rehearse your greeting a few times before you press record. Plan your pauses and select natural places to take a breath. If you are recording directly into your phone don't hold it to your ear like you are talking on the phone. This can produce a muffled tone. Hold the phone out in front of you a few inches from your mouth for the clearest recording. This may require some trial and error. So playback your greeting and make necessary adjustments on your re-record.
