While a short recording may not seem like a place to win new business, the professionalism, courtesy, and clearness that you convey in your greeting will leave a favorable impression in a customer's mind.
Hello, you have reached the dental office of Dr. X. We are busy assisting a patient now, but will call you back as soon as possible. Please leave your name, reason for calling, and your number. If this is an urgent enquiry, please call 911. In this case, the dentist is giving a reason for not being available and they’re providing a way to prioritize the patients who need the most help. They’re also leaving an emergency number for the most severe of situations.

As a real estate professional, you're always on the go. Whether showing homes and apartments to a prospective client or staging a home for sale, it's likely that you're out of the office quite often. Anyone in the industry knows that, out of the office is a good place to be. Unfortunately, it makes staying professional just a little bit harder. What happens when you're working with one client and another one calls? Most likely, you send that call to your voicemail box, but what does your voicemail greeting say? What should voicemail messages include? If you're voicemail isn't offering the right information, you might lose a sale.
