The voicemail greeting should be multiple choice and include things like the name of your company, an automated response that is friendly and informative, and information on how to contact you by phone.
In a concise fashion, you should relate the hours your business functions, and note any potential conflicts such as holidays or business closures. Use an auto attendant if you have more than one menu option for the customer, such as a voicemail box and an emergency support line.

Great question! Although I don’t know if there is a specific function for this on your particular phone, the best way to save the message is the simplest. Turn up the sound as high as you can and record it onto a digital recorder (like you would use for a lecture), a cassette recorder or your cell phone if you have a voice recorder on it. Then save it as an MP3 on to your computer for safe keeping. You can also Google your vtech model number to see if you can find an owner’s manual. They might have a way to save a recording in there. Probably not, but it’s worth a shot.
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.
