Abstract
A system is provided for securing voice mail messages. The system includes a packet network and a telephony device that is coupled to the packet network. The system also includes a voice mail system that is coupled to the packet network and that receives a voice mail message from a caller attempting to communicate with a user of the telephony device. The voice mail system encrypts the voice mail message using a public key associated with the telephony device and stores the encrypted voice mail message in an open file system coupled to the packet network.
