VoIP Access Gateway and inter-Local Call Processing Method thereof

摘要

PURPOSE: A VoIP access gateway and an inter-local call processing method thereof is provided to perform call process for a VoIP between a proxy server and an analog terminal and enable call connection between local terminals without using the proxy server. CONSTITUTION: A call processor(213) transmits and receives an SIP(Session Initiation Protocol) message for outgoing or incoming of a local subscriber to and from a proxy server(140) in order to connect a call. If the outgoing or incoming of the local subscriber is the call connection between the local subscribers, the call processor uses an IP address thereof instead the proxy server IP address as a destination IP address of the SIP message. Therefore, the SIP message is processed without being transmitted to the proxy server.
