An increasing number of U.S. companies have signed up for voice over IP (VoIP), but many businesses still rely on more conventional telephony solutions.

In a new report, market research firm In-Stat revealed that while 20 percent of all U.S. companies use VoIP today, 44 percent of organizations using IP telephony still have at least some conventional TDM, circuit-switched phone lines.That said, In-Stat is forecasting continued IP telephony growth in the coming years. By 2011, 33 percent of all companies are expected to use VoIP in some capacity, In-Stat said. Thirty-six percent of the companies that have deployed IP telephony are actually using products from multiple vendors.

The market research firm said smaller businesses are most drawn to broadband IP telephony products while IP PBXs appeal to large companies. About 14 percent of companies are using some form of voice-enabled IM.

In-Stat said it expects hosted IP telephony revenue to surpass that of broadband IP telephony (BBIPT) by 2010.
