Abstract: A Voice over Internet Protocol (VoIP) service system using Network Address Translation (NAT) and a method of processing a packet in the system. The method includes the steps of: looking up a private address of a terminal located behind a NAT device in a previously generated NAT table using port information included in a packet transferred from a terminal located outside the NAT device to the terminal located behind the NAT device; and when a packet is transferred from the terminal located behind the NAT device to the terminal located outside the NAT device, generating an IP conntrack having the private address of the terminal located behind the NAT device as an originating address and having a public address of the terminal located outside the NAT device as a destination address.

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.

Abstract: A method and apparatus for transmitting a groupcast to support a voice paging service in a VoIP system are provided. In the method, a voice paging message is received from a voice paging transmitting terminal and one or more voice paging messages are reproduced from the received voice paging message. A group table is used to change the destination address and port of each of the reproduced voice paging messages into the IP address and port of each of one or more voice paging receiving terminals. Each of the reproduced voice paging messages is unicast on the basis of the changed IP address and port.
