Microsoft and videoconferencing specialist Picturetel have pitched a technical standard for Internet telephony systems, in the hope of speeding up the acceptance of a specification. Their proposal is in direct competition with a rival submission from AT&T and Cisco.
The companies made their proposal to the International Multimedia Telecommunications Consortium (IMTC), a group of vendors seeking to raise awareness and acceptance of the H.323 videoconferencing specification, which is endorsed by the International Telecommunications Union (ITU).
Microsoft and Picturetel's technology is known as G.723.1 and covers a narrow-band audio codec within H.323. It is backed by leading vendors in the conferencing sector such as Intel and Databeam.
The G.723.1 specification competes directly with a codec technology put forward by AT&T and Cisco Systems known as G.729. A decision regarding the choice of proposal is expected during the IMTC?s next meeting in March.
By agreeing to a single codec developers will be able to guarantee interoperability among Internet telephony applications.
But Keith Mitchell, chairman of Linx, the London Internet Exchange, warned that too many competing 'standards' could kill the Internet. The closer the ITU gets to implementing a single standard the better, he said. ?A large number of companies are rushing out Internet telephony products, making up their own standards. They are only interested in grabbing market share and have no regard for Internet congestion,? he commented.
