Abstract
Abstract A voice message storage device receives, stores and plays back voice messages transmitted on a telephone line. The device includes a first analog recording tape unit associated with a first identification signal and a first password, and a second analog recording tape unit associated with a second identification and a second password. An identification signal detecting unit is provided for detecting dial pulses or DTMF signals, denoting the identification signal and password for accessing the first or second analog recording tape unit.
