Recording professional voicemail greetings is easy but many people find it to be akin to public speaking, and are therefore apprehensive about starting. First of all, lets acknowledge the elephant in the room and just say that nobody in the history of the world enjoys the sound of their voices being played back to them. Once you can accept that, getting a professional voicemail greeting or Auto Attendant menu recorded will be a lot easier. To help you get the right tone and tenor of what you’re trying to communicate over you business voicemail, we’ve put together this handy list of resources for you.
For a medical office, call types may include billing, emergencies, appointments, cancellations, etc. 2. Determine How To Best Route Calls The best method of routing your medical office calls will depend on your office size and budget. If you have a small staff, setting up a standard voicemail greeting system may be a more practical approach. For a larger health organization with multiple departments, it makes more sense to route calls to their intended destinations by using an auto attendant. For example, “If you have a question about billing, press 1. If you’d like to schedule an appointment, press 2. If this is a medical emergency, press 0 for an operator.” If you want every caller or patient to experience a professional and compassionate call, you may consider working with a medical office answering service. You can forward calls to an answering service after business hours, on holidays, during overflow, or any other time you may need help answering calls. 3. Draft A Script

Context does matter here. If the caller would reasonably expect you to answer the phone (such as if they were calling a store or other place of business), an apology for not being able to get to the phone makes the most sense.
