Abstract
A telephone system having a message recording function includes a message receiving system that is connectable to a calling station to the telephone system through a telephone line and receives a message transmitted from the calling station through the telephone line, a message storage in which the message received by the message receiving system is stored, a message reproducing system that retrieves and outputs a message stored in the message storage. With this configuration, the message reproducing system reproduces the message with the telephone line being in the off-hook state.
