Expanding on the simple approach above, let the caller know who they've reached. This will not only eliminate people leaving voicemails by mistake, but it will reassure the caller that they have called the number they intended.
A professional voicemail greeting is slightly different than a business greeting, as certain professionals may require the caller to leave specific information. For instance, a professional therapist voicemail greeting would specifically ask for contact information from the caller, as well as leave their own personal contact information in case the caller is having problems. Hello, thank you for calling the office of Dr. Harold Tweed. I can’t come to the phone right now; please leave your name, number, and message at the tone. If this is an emergency, please contact either my personal assistant at 555-555-2345 or myself at 555-555-3234 and we’ll get back to you as soon as possible. Thank you for your call. Include your name/business Ask for their contact information and message Provide them with alternate phone numbers if this is a crisis Extend gratitude for their call Funny Voicemail Greeting

While it is important to address their concerns head-on, you may not be able to answer each call as it’s received. Make sure you use best practices for dealing with angry customers, and that your voicemail greeting sets the appropriate tone. Avoid defensive language, validate their concerns, and keep them informed as to how you are handling the situation.
