Embodiment Construction

[0027] Figure 1 is a block diagram of an Internet (IP) telephony system embodying the principles of the present invention. As shown, an IP-PBX 14 implementing channel switching of at least one legacy terminal 16 is connected to PSTN 10 through a central office card (or station circuit) (not shown). Although not fully described in the present invention, central office trunk cards for interfacing E1 / T1, PRI / BRI / No. 7 signaling are well known in the art. Furthermore, channel connection via an originating / terminating terminal, more specifically at least one conventional terminal, eg an analogue telephone or a digital telephone, is also a known technique. Therefore, embodiments of the present invention will focus on call connection services between legacy terminals and IP terminals, call connection services between IP terminals, and IP trunking (VoIP connection through a gateway) from legacy terminals / IP terminals.

Abstract

Disclosed is an apparatus and a method for placing calls between legacy terminals and IP terminals in an IP-PBX system. Features that were once only used in traditional PBX telephone systems, like group ring services and station group services are now made available for IP terminals in an IP-PBX system. Methods of providing station group service and ring group service to both legacy terminals and IP terminals in an IP-PBX system is disclosed.

Description

[0001] Pursuant to 35U.S.C119, this application claims that I filed an application with the Korean Industrial Property Office on October 13, 2001, with the serial number 2001-63240, entitled "Method for Providing Station Group Service in Internet Telephony Switching System" ", the contents of which are hereby incorporated by reference. Field of Invention [0002] The present invention relates to a method of providing station service in a network telephone switching system having a configuration capable of controlling IP terminals and conventional terminals. Background technique [0003] Recently, the Internet has rapidly expanded to most parts of the world. In order to meet the needs of various services, IP has been developing rapidly in terms of the performance and services it provides to users. Users are not satisfied with this, but continue to demand more diversified services. One example is the transmission of voice signals using an IP network (or VoIP: Voice over Inter...
