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.

Abstract: A cordless telephone in which communication between a base unit connected to a telephone network and a handset unit is carried out by radio waves, includes a transmitting and receiving system in the base unit and a transmitting and receiving system in the handset and first and second control circuits provided in the base unit system and in the handset, respectively, each include a detecting circuit for detecting whether any signal is present in an initally selected channel at the time communication is to be initiated between the base unit and the handset unit. Such signals being present in the initially selected channel may be caused by interference from other cordless telephone systems in the vicinity. Channel selector apparatus acts to change the base unit and handset from the occupied channel to a vacant channel. Depending on whether it is an incoming call or an outgoing call either the first control circuit of the base unit or the second control circuit of the handset selects the vacant channel in response to an instruction command from the other control circuit.

Abstract: A telephone set (1) stores a message and a telephone number of each telephone set (2 to 4) to which the message is to be transferred, and reads out the telephone number to perform dialling for the destination telephone set (2 to 4). If no voice signal is sent back from the destination telephone set (2 to 4) within a predetermined time interval after the connection is established, the telephone set (1) reproduces the recorded message and sends it over the telephone lines to the destination set (2 to 4). The operation is automatically repeated for each designated destination telephone set (2 to 4), thereby automatically transferring the same message to a plurality of destination telephone sets (2 to 4). … …
