Explain Your Return Call Policy: In your after hours message for the medical office, be sure to state your return call policy for voicemail response. By giving callers an estimate of when they can expect a return call from someone in your office, you can eliminate multiple phone calls from the caller, as well as reduce work for your staff members.
When your business is closed for vacation or holidays, it’s imperative that you set appropriate expectations for a callback and to provide an alternative coverage option, if available. The following greeting accomplishes this succinctly.

Here are some proven techniques for how to leave a voicemail message that gives you the best chance of getting a call back: Say the person's first name ONLY. Say your first name only followed by your company name. Keep your voicemail brief and urgent. Leave a reference name of a person and company you've worked with. How do you answer the phone professionally? Promptly answer calls. The average ring takes 6 seconds. Be warm and welcoming. Introduce yourself and your business. Speak clearly. Do not use slang or buzz words. Ask before you put people on hold. Don't just put calls through. Be prepared for your calls. How do you greet a client over the phone? Answer your phone with a "Hello" if you don't know who it is. Greet the caller by name if you know them. Use informal language with family and close friends. Introduce yourself by name when you call someone else.
Having a dedicated emergency contact will help make sure anything important that comes up is taken care of. Another option is directing callers to a separate answering service.
