Any method of storing and forwarding messages in computer telephony. Fax mail, voice mail, and broadcast messaging are all examples of this.

A recorded voice message, for example, can be stored for later playback either locally or remotely, and a fax can be received and stored before being re-transmitted to the intended recipient. Messages can vary in content and media type, with the difference being that they are recorded or saved for later retrieval.
