METHOD FOR CONTROLLING GROUP TERMINATING CALL IN VOICE OVER INTERNET PROTOCOL SYSTEM

摘要

A gatekeeper of a voice over internet protocol (VoIP) system controls an incoming call directed to a group. The gatekeeper carries out the steps of: defining a plurality of terminals selected by an operator request as the group for taking a group call service, creating terminal information for the terminals and group information for a plurality of defined groups in the form of a table, and managing the table; and determining, using the table, whether the incoming call is directed to the group upon receiving the incoming call, generating a group call using the group information if the incoming call is directed to the group, and transmitting the group call to respective members belonging to the group.
