You are a doctor's office and you just received the awaited new vaccine in stock. All of your patients need to know.

You ask your office staff to "call" every patient. They set up InphoniteVoice to say, "This is Dr. Smith's office calling to let you know that we have the new flu vaccine available. You may come in anytime during office hours. However, there may be a wait. If you prefer to schedule an appointment, press 2 now to speak to the operator, or call 555-555-9876 between 8am and 5pm."

Your patients start coming in, scheduling and getting vaccinated. You charge a nominal fee. It adds up, and you have healthy patients. As an added bonus, you just contacted those patients that haven't been in for a long time and some of them call in for check-ups and refer family or friends for vaccines or appointments as well.
