PURPOSE: To repeatedly make a telephone call a lot of times in a short time from a hand set until a telephone set at the destination responds to it.

CONSTITUTION: When the telephone number of the telephone set at the destination is inputted from a key input part 25 of a hand set 2 after a radio link is stretched between a base unit 1 and the hand set 2 by pressing the line wire button of the key input part 25 of the hand set 2, the base unit 1 turns on a switch 11, catches a line, transmits a dial signal corresponding to that telephone number from a dialer circuit 12 onto a line 3 and calls that telephone set. As a result, when the destination does not respond to it and a ticket button installed at the key input part 25 of the hand set 1 is pressed, in the state of still stretching this radio link, the base unit 1 temporarily releases the line, immediately catches it, transmits the dial signal onto the line 3 again and calls that telephone set again. Afterwards, only by pressing the ticket button until the telephone set at the destination responds to it, the telephone call can be automatically made to that telephone set a lot of times in a short time.
