A method allowing centralized call control data management and improved maintenance efficiency of call control data for a plurality of call agents distributed in the packet-based network is disclosed. Each of the call agents is set to be a client of a server, which stores master call control data required in respective ones of the call agents and manages the master call control data. Each of the call agents stores a copy of corresponding master call control data so that the call agents perform network-wide call control.
