Summary:PROBLEM TO BE SOLVED: To provide a call control device capable of setting the number of shared exterior lines which are shared with other call control devices among a plurality of exterior lines accommodated in the present call control device, to any arbitrary number and originating a call from an interior line accommodated in the present call control device to the shared exterior line accommodated in the other call control device.SOLUTION: When there is an incoming call to a shared exterior line accommodated in a present call control device 1, a call control section 10 transmits a shared exterior line incoming call notification message for reporting the call incoming to the shared exterior line to all the other call control devices 1.
