Before we get into business voicemail greetings, here are some interesting facts about voicemail messages to think about. 75% of all business calls are not completed on the first attempt. 60% of all incoming calls are less important than the work they interrupt. 90% of all written messages contain incomplete information.
I have a confession to make: I haven't recorded a new voicemail greeting in nearly a decade. Since then, I've (hopefully) become more articulate, poised, and self-assured. But hear my voicemail recording, and you'd think I was still new to the work world, a little unsure of myself — and probably not an authority.

3. Push the asterisk (*) or pound (#) key and then press the call button to call your voicemail. In some cases, you might not need to press the call button but you usually will have to listen to an automated greeting before you can hear your voicemail. Check to make sure that the asterisk or the pound keys are the correct buttons to press. Which key to press and when to push can depend on your cell phone provider. For most cell phone companies, it's often one of these buttons. Try both, and if neither of them work than visit the website of your phone company or call customer service.
