If you have an assistant, include their name and contact information in your greeting. If you have a hard time delegating tasks, this is an excellent way to start building it into your processes.
Most businesses will automatically play a recording if you try to call their office when they are closed. An after hours announcement is a professional way to notify callers of important details, rather than making them wait for the call to failover to a voicemail box or other destination.

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
The above section details types of phrasing to avoid; however, it doesn’t detail what users should NOT say on their greeting. Though this is a bit loaded, as there are hundreds of combinations of things one shouldn’t say, there are some key components users should ALWAYS avoid. a. Forget About Slang: You should strive to be as professional and welcoming as possible in your greeting. While this may steer you towards using slang, in an attempt to make callers comfortable, it’ll most likely work against you. As a professional, your demeanor, tone, and speech should be clear cut and well articulated. Using slang undercuts this and works against you. b. Don’t Even Think About Profanity: This is a no-brainer. Never, under any circumstances, curse in your greeting EVER! c. Keep Your Sentences Clean, Don’t Ramble: Introduce yourself and give your caller specific direction. Avoid long diatribes detailing tangent thoughts. Keep it simple and quick. d. Always Return Your Calls: It’s important for callers to feel they are valued. Nothing dissolves this quicker than a greeting that doesn’t stress this. For example, “I’ll call you when I can,” “If I don’t return your call, please call back”—these phrases are terrible and completely destroy any good will you may have with a caller.
