While it’s not necessary to memorize the script, it’s an added advantage when your call representatives have practiced reading it over and over again. By doing so, the flow of the script is clear to them. This familiarity can avoid confusion or dead airs during the call when your callers may be confused as to what the next word may be, for instance.
A secretary in a doctor’s office creates a voicemail greeting that says, “If you have a scheduled meeting with us, we could use copies of all your medical documents from last year, so come prepared.” Using the word “could” gives patients the impression that they don’t necessarily “need” last year’s documents. See the difference between “could” and “need”? Your word choice can impact a future meeting significantly. If you want a customer to perform a specific action, you need to pay close attention to how you express your calls-to-action.

When it comes to doing business efficiently, I say it's time to hang up on voicemail.
Business voicemail greetings are rarely thought of as a prime way to connect with customers. But just because you're not available doesn't mean you can't make a positive impression on your customers when they reach your voicemail box.
