    • PURPOSE: A system for determining media path between IP phones in a VoIP system is provided to construct network location information of IP phones and decide an optimal media path. CONSTITUTION: A VoIP PBX(Private Branch eXchange) receives a call connect request signal from an originating internet protocol phone(801). The VoIP PBX checks identifications of call originating IP phone and call receiving IP phone in a hierarchical position information table(802). The VoIP PBX decides whether the call originating IP phone exists in the same private network of the call receiving IP phone(803,804). If the call originating IP phone and the call receiving IP phone are in the same private network, the VoIP PBX establishes the media path between the receiving IP phone and the originating IP(805).
    • 目的:提供一种用于确定VoIP系统中IP电话之间的媒体路径的系统,以构建IP电话的网络位置信息,并确定最佳媒体路径。 规定:VoIP PBX(Private Branch eXchange)从源IP网络电话(801)接收呼叫连接请求信号。 VoIP PBX检查分层位置信息表(802)中的呼叫始发IP电话和呼叫接收IP电话的标识。 VoIP PBX决定呼叫始发IP电话是否存在于呼叫接收IP电话的同一专用网络中(803,804)。 如果呼叫源IP电话和呼叫接收IP电话在同一专用网络中,则VoIP PBX建立接收IP电话与始发IP之间的媒体路径(805)。
