Abstract
A VoIP network includes an integrated Internet telephony system having an all-in-one architecture in which an application layer gateway function, a signaling processing function and a media processing function 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 connected to a public network and an internal SIP terminal 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, a media gateway function and SIP-ALG function 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.
