PROBLEM TO BE SOLVED: To make it possible to surely and quickly contact a user of a call destination by one dialing or by one entry of a number even in the case that the user of the call destination has pluralities of terminals. SOLUTION: In the case of detecting dialing from a caller transmission 1 to a terminal 3a, a 1st network informs a terminal management server 2 of a telephone number of a call destination. When the terminal management server 2 recognizes it that the user of the terminal of the call destination is Mr. A and only terminals 3b, 3c among terminals used by Mr. A are available of call reception, the server 2 informs the 1st network of the telephone number of the terminal 3b among the call reception available terminal. Upon the receipt of the telephone number assigned to the terminal 3b, the 1st network gives the number to a 2nd network to request call processing of the call. The 2nd network calls the terminal 3b.
