PURPOSE:To enable automatic calling of a recipient and transmitting of a message by allowing a caller of telephone to record necessary message beforehand and register and accumulate called subscriber's number. CONSTITUTION:A voice message is recorded in a recording-reproducing part MT using a microphone MIC by operating an operating board KEY of an automatic voice messaging device MS. Then, subscriber's number of the recipient is accumulated in a subscriber's number registering part MEM by the operating board KEY. When a start command is made from the operating board KEY, the central controlling part CONT gives a command to an idle subscriber's circuit detecting unit FDET. When an idle circuit is detected, a registered number is detected from the registering part MEM. Dial sending is made by the central control part CONT. If a busy tone is sent back from the switch-board after dial sending, it is detected by a busy tone detecting part BDET. Calling operation is made again a specified time after restoring the circuit. When it is not busy, a ringing tone is detected by a ringing tone detecting part RDET and the message is sent after a reply is made. |
