ABSTRACT:
A method for registering a telephone number for executing an automatic calling function in a cordless telephone system comprising a base station and a "flip-type" remote handset. The base station includes a hook switch for forming a calling loop, a VOX circuit for detecting a non-voice state, a tone detector for detecting a busy tone for informing the state of unavailability of the subscriber's telephone, a memory for registering a telephone number of a destination subscriber thereto and a speaker phone for establishing a telephone call through an external microphone and a speaker. The "flip-type" remote handset includes a flip switch for detecting an opening state and a closing state of a flip and a call key for a calling request. The automatic calling function is executed by: receiving a key input signal corresponding to a telephone number of destination subscriber for registration into a memory; establishing an automatic calling mode for automatically calling the destination subscriber and dialing the registered telephone number upon a calling request; and cutting off the calling when a calling end is detected and converting the automatic calling mode into a call standby state.
