.Oh - if anyone is still curious: I recorded the greeting via the phones custom greeting function, then called to listen to it from another phone, then turned off the phone and called again. Same message. I had wondered if just maybe the phone played the message when on, and the carrier played the message when the phone was unreachable.

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.
