Title: Telephone system
Inventor: TOMITA WATARU
IPC: H04M3/42
Filed: 1998-02-09
Abstract: PROBLEM TO BE SOLVED: To provide the telephone system that easily discriminates whether or not a present phone call is replaced with a new phone call if an another phone call comes in during a busy state. SOLUTION: Upon the arrival of a new phone call during a busy state, a speaker of a receiver outputs an interrupt tone (S11), a loudspeaker of a main body sounds a beep tone (S12) to inform a talker of the incoming of a new phone call. A caller number sent from an exchange is received (S13: YES). When a registered name corresponding to the caller number is stored, the name is displayed on an LCD (S14: YES, S15). When not stored, the caller number is displayed on the LCD (S14: No, S16).  In the case priority stored in a priority area corresponding to the newly received caller number is higher than the priority stored in a priority memory (priority of the present phone call) (S17: YES), the display of the LCD is blinked (S18) and a beep tone is sounded from the loudspeaker of the main body (S19) to inform the talker of the incoming of the new phone call with higher priority, since it means that the new phone call has a greater priority than that of the present phone call.
