A terminal adapter management system includes a service center (3) that is connected through telecommunication networks (1, 2A-2N) to terminal adapters (10, l0A). The service center carries out, through the telephone networks, the initial setting and renewal of called party's telephone numbers, common carrier identification numbers, exchange telephone numbers and a toll table which are stored in advance in a memory device of each terminal adapter (10, l0A). Each terminal adapter delivers a called party's telephone number, a common carrier identification number, or an exchange telephone number in response to a user's telephone connected to the terminal adapter being taken off-hook or a called party's telephone number being input through the user's telephone, to thereby selectively achieve a direct-dialing function, an auto-dialing function or a routing function.
