Microsoft Corp.stated that it has licensed its RT Audio Codec for VoIP to major hardware vendors, including Intel Corp., Texas Instruments Inc. and Polycom Inc. Also, on Oct.16, the Redmind based software giant will release the Office Communications Server 2007, which is its next enterprise telephony and collaboration platform.
Microsoft is moving in on the IP telephony market from the software side while Cisco Systems Inc. approaches from the data network end. The CEOs of both companies said yesterday that the market is quickly shifting to so-called unified communications and they will make sure their products work together even as they continue competing in some areas.
Research backs up that sense of rapid change. Not including phones, 39% of revenue in the worldwide enterprise telephony market went to IP instead of traditional circuit-switched infrastructure in the second quarter, according to Dell'Oro Group Inc. analyst Alan Weckel. That's up from 31% in last year's second quarter.
Small and midsize businesses, latecomers to IP telephony, are now joining in, he added. Looking for big-company features such as the ability to have employees make calls from anywhere in the world using a software phone on a PC, these smaller players installed one IP line for every three traditional connections in the second quarter, Weckel said. A year earlier, only 19% of the lines they installed were IP.
IP telephony makes voice calls, video and conferences into a series of data packets so only one network is needed, and those functions can be integrated with other applications.
Microsoft developed RT Audio Codec and uses it in OCS, the PC-to-PC calling feature in Windows Live Messenger and the voice-calling features in the XBox Live online gaming platform, Patterson said. The software compresses digital speech samples into packets and then decompresses them. Now third parties are licensing the codec and building it into products such as chips and phones. Other licensees include AudioCodes Ltd., Dialogic Corp. and LG-Nortel Co., a communications joint venture of LG Electronics Inc. and Nortel Networks Corp.
RT Audio Codec has security built into it that is missing in other codecs, and it can adapt to poor network connections so users can communicate in more places, Microsoft's Patterson said. |
