A vehicle-installed telephone apparatus comprises a portable phone with announcing means controlled by a microcomputer, running detecting means which detects that a vehicle is running, incoming call detecting means which detects that an incoming call is received and control means which sends control signals to the portable phone. The control means sends control signals which invalidate the operation of the announcing means to the microcomputer within the portable phone, when the running detecting means detects that the vehicle is running and the incoming call detecting means detects that the incoming call is received at the same time, whereby a driver can concentrate on driving without being diverted his attention, even if an incoming call is received while driving.
