Abstract
Abstract The invention discloses a telephone set and a method for its operation for storing a message and a telephone number of each telephone set to which a message is transferred, and reading out the telephone number to perform dialing for the destination telephone set. If a continuous period of silence is sent back from the destination telephone set for a predetermined time interval within a larger predetermined time interval after the connection is established, the telephone set reproduces the recorded message and sends it over the telephone lines to the destination set, otherwise the telephone set disconnects from the telephone line. The operation is automatically repeated for each designated destination telephone set, thereby automatically transferring the same message to a plurality of destination telephone sets.
