You need to portray a sense of confidence, authority, and respect. If you would like to leave a voicemail message for an inmate, you must first have a Prepaid Account. I was trying to put together the puzzle of my life and realized there's a piece missing - you.
Nobody wants to play phone tag. Skip the back and forth by explicitly telling the caller to leave their name, number, and the best day(s) and time(s) to reach them. Your clients will appreciate you not wanting to waste their time.

No24: You have reached the CPX-2000 Voice Blackmail System. Your voice patterns are now being digitally encoded and stored for later use. Once this is done, our computers will be able to use the sound of YOUR voice for literally thousands of illegal and immoral purposes. There is no charge for this initial consultation. However our staff of professional extortionists will contact you in the near future to further explain the benefits of our service, and to arrange for your schedule of payment. Remember to speak clearly at the sound of the tone. Thank you.
Keep it Brief. Time is money in business, so if your voicemail is long, chances are the caller will simply disengage before the cue to leave a message even sounds. Keep your voicemail short. The most should be around 30 seconds, and even that’s pressing it. We’ve grown into a country where our attention span can last only about 10 seconds in some cases, so keep it short, brief and to the point. Persuade and Engage the Caller. If someone calls your business, they already have an intention. It’s the quality of your voicemail that plays a factor if they consider you a company they’d like to deal with. This is your chance to motivate someone to engage in a meaningful conversation with you. If your voicemail is shoddy, chances are they’ll hang up, or lose motivation to continue the call. In other words, your voice mail must engage and entice someone to the point that they care enough to leave you a message.
