1. A method for managing call control data installed in respective ones of a plurality of call agents which is distributed on a packet-based network, comprising the steps of:
- a) setting each of the call agents to be a client of a server which is provided on the packet-based network by the steps of;
a.1) the call agent transmitting a server search message to the server;
a.2) when receiving the server search message, the server determining whether the call agent can be managed;
a.3) when it is determined that the call agent can be managed, the server transmitting a response message back to the call agent;
a.4) when receiving the response message, the call agent transmitting a registration request to the server; and
a.5) when receiving the registration request, the server registering the call agent as a client when the call agent satisfies registration requirement;
wherein when it is determined in the step (a.2) that the call agent cannot be managed, the server transmits a re-search instruction message to the call agent, the re-search instruction message designating another server, and wherein, when receiving the re-search instruction, the call agent transmits a server search message to the designated server;
at the server,b) storing master call control data required in respective ones of the call agents;
c) managing the master call control data; and
at each of the call agents,d) storing a copy of corresponding master call control data so that the call agents perform network-wide call control.

Abstract
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.
