  • Method for controlling multi-channel voice data of gateway system and apparatus thereof
    Patent number: 6674761
    Abstract: A method and its apparatus for controlling multi-channel voice data in a gateway system between voice network such as a public switched telephone network (PSTN) and an internet network, in which a plurality of memory regions of channel buffer are statically allocated, to each of which an RTP header is allocated, and a voice packet received from the PSTN network and a voice packet received from an IP network are transferred, by which, a processing speed is remarkably reduced, and more channels can be accommodated.
