Ray and folks check this out from IBM: internet.ibm.com BM Internet Phone Connection is the first step in the recent evolution and integration of IBM technologies. IBM based Internet Connection Phone on real-time voice transfer technology thereby enabling voice transmission through what used to be data-only networks. But IBM technology goes beyond just providing the voice transmission. An IBM research team addressed many of the transmission problems typical of sending voice over data networks. Other incarnations of voice transfer technology have problems with echos and lost packets that lead to transmissions with lots of break up. IBM modified the GSM compression/decompression (codec) algorithm (the European cellular telephony standard) in such a way as to suppress echos and to better control the loss of packets. The new algorithm compresses 8-Khz 16 bit voice samples to 9400 bits per second (bps) leading to clear, near echoless conversations. IBM researchers continue to integrate other standard codecs such as G.723 and wide-band coders into the improved framework as they become available. The goal is to support a full H.323 network videoconferencing standard. Internet Connection Phone takes full advantage of IBM's Mwave technology -- the technology that more efficiently processes multimedia and audio data -- whenever it can. A computer that has an MWave installed can offload the Internet Connection Phone's compute intensive compression and decompression. This way the computer can do other tasks more effectively while Internet Connection Phone is working. In addition to IBM's innovative technology, IBM is leading the charge to standardize Internet phones so that users can talk to any Internet phone users independent of vendor. I will be checking this out over the next few days, and let you folks know how it works!!
