Your Panasonic cordless phone might come with a built-in answering machine. You can deactivate the answering machine either from the base unit, from a handset or remotely by dialing in to your phone. Once the answering machine has picked up a call, however, you cannot cancel it until you hang up or you reach the maximum message recording length. If your unit doesn’t have an answering machine, then voice mail is provided by your telephone carrier, not by your Panasonic cordless phone. Warnings Writer Bio
