ALL-IN-ONE VOICE OF IP SYSTEM INCLUDING MULTI-FUNCTION AND METHOD OF PROCESSING SIGNALLING THEREFOR

摘要

An integrated Internet phone system and a signaling processing method of the system are provided to enable an SIP signaling gateway, a media gateway, and an SIP-ALG to carry out functions at the same time within one equipment. An SIP(Session Initiation Protocol)-ALG(Application Layer Gateway) module(130), an SIP signaling gateway module(120), and a media gateway module(150) are realized as software function blocks on one chip. The SIP-ALG module performs an SIP-ALG function. The SIP signaling gateway module processes an SIP signaling message, and sets a call session for an Internet phone service. The media gateway module processes an RTP packet including voice data. An LAN interface(110) transceives data with a private VoIP network. A WAN interface(160) transceives an RTP packet and an SIP signaling message with the Internet. A virtual interface(140) enables the media gateway module to transceiver the RTP packet.
