ABSTRACT:
A communication apparatus having an automatic dialing function such as redial, one-touch dial, abbreviated dial comprises: a memory to store the dial number; a detector to detect a predetermined hooking operation by another terminal; and a transmitter to transmit a dial signal according to the dial number stored in the memory on the basis of the detection of the predetermined hooking operation by the detector. The detector has a second detector to detect an off hook of another terminal. The transmitter sets a predetermined flag on the basis of the detection of the predetermined hooking operation and, when the off hook is detected, if the predetermined flag has been set, the dial signal according to the dial number stored in the memory is transmitted.
