“Thank you for calling [company/person’s name]. We are currently unavailable, but if you leave your name, phone number, and message, we will get back to you as soon as possible.”
Don' let background noise do the talking for you. Ambient noise on your recording could be sending the wrong message to your clients. The sound of your kids arguing in the distance could be the sign of a distracting work environment. Clinking glasses and restaurant chatter may leave the impression that you don't take your work seriously. When you record your voicemail greeting choose a quiet spot free from interruption, so your message is the only thing callers hear. It's also good to avoid large, cavernous spaces where sound verberates.

Reiterate the main point of your message and repeat your name and phone number. This will help the receiver remember your name and message and spares him from having to listen from the beginning to write down your contact information.
