ABSTRACT:
An Internet telephone system architecture having low latency and permitting voice communication between telephones and computers is disclosed. The architecture permits dynamic packet-to-packet change in various factors to adjust for Internet conditions. A forward error correction algorithm provides a variable level of redundancy from zero to three in the transmission of data packets. The level of error correction redundancy, the codec selection and other factors, are dynamically changeable by a voice port to replace lost packets without interpolation and to thereby maintain the highest voice quality and data compression ratio that is consistent with the quantity of packet loss.
