    摘要: A VoIP network includes an integrated Internet telephony system (100) having an all-in-one architecture in which an application layer gateway function (130), a signaling processing function (120) and a media processing function (150) are integrated. The integrated Internet telephony system performs ALG processing on a packet bound to a first address and processes a signaling message bound to a second address so as to set up a call session between an external SIP terminal (105) connected to a public network and an internal SIP terminal (102) connected to a private network, and performs media processing on an RTP packet based on a third address, the RTP packet exchanged through the call session. A SIP signaling gateway function (120), a media gateway function (150) and SIP-ALG function (130) are installed in one chip, and respective functions are allocated with different IP addresses by the application of a virtual interface and aliasing IP addresses.
