Radio telephones

An information storing apparatus is provided in a radio telephone apparatus having a base unit 1 coupled to a wired telephone line 3 and a radio telephone set 2. The base unit includes a memory 40 for storing telephone number information and a line relay 33 for making or breaking a speech path between the base unit and the wired telephone line. When a registration signal (#, from key 32a) is transmitted from the radio telephone set, the base unit is disconnected from the wired telephone line to break the speech path. Thereafter, if a dial signal (from keys 32) from the radio telephone set is received, the received dial signal is stored in the memory as the telephone number information used for a reduced dialing operation. If a calling signal arrives at the wired telephone line while the dial signal is being stored, the calling signal is detected by another telephone apparatus 50 coupled to the wired telephone line. Therefore, the telephone apparatus generates a ringing signal in response to the detected signal.
