The professional voicemail greetings is the cornerstone of any good business. Not every voicemail recording is relevant to every situation. This guide is going to demonstrate some of the specific custom voicemail greeting examples for doctors, dentist, real estate agent, lawyers and other professionals. A doctor’s practice typically either has a secretary or the doctor themselves to take calls. It’s vital that you have a different voicemail based on the area of the practice the patient is calling. The information differs, but the tone of voice remains the same. It should be warm yet professional because many patients will be distressed or worried about potential symptoms and conditions.

Traditional voicemail services once offered this feature, but visual voicemail (with a visual interface that lets you access messages directly) has mostly eliminated that possibility. If your phone does not have visual voicemail, and you have to call an inbox to hear your messages, you may still be able to use this feature.
You might also consider giving them the option to skip your voicemail message completely by pressing another key (again, check with IT). You also want to make callers aware what you will return their call, instead of telling them that you will try to return their call--and let them know when you are likely to do it, if possible. If necessary, provide additional or emergency information in your voicemail greetings. My dentist, for example, lists his cell phone number for emergencies.
