Summary:PROBLEM TO BE SOLVED: To select the desired one of plural call tones and to accurately deal with the telephone calls by analyzing the originating number, i.e., the transmitted telephone number of a caller terminal, detecting whether the originating number is included in the registered telephone numbers and outputting the call tone corresponding to the coincident telephone number if detected. SOLUTION: When an originating number display function is turned on, a microcomputer 24 can set a priority call function and also an opposite part- based call tones via a key matrix 30 which inputs the telephone numbers, etc. These set contents are written into a nonvolatile memory E PROM 32. Then a microcomputer 24 analyzes the telephone number sent from a network via a caller IDIC 20. The analyzed telephone number is compared with the telephone number that is registered on a master unit or slave unit register table. If the corresponding telephone number is detected, the priority call processing is carried out by means of a set call tone.
