Campbell, Calif. — Worldwide VoIP telephony revenues grew to $24 billion in 2007, an increase of 52 percent, according to a report from the research firm Infonetics.
The growth follows a similarly strong showing in 2006, when VoIP revenues jumped 66 percent.
According to Infonetics, residential VoIP services are growing at a faster clip than managed IP PBX services. The number of worldwide VoIP users hit 75 million in 2007 and 26 percent of those were business customers. Infonetics predicts that businesses will grab a 41 percent share of the global VoIP market in 2011.
In the United States, Comcast is the market-share leader, with 20 percent of the market, according to Infonetics.
"While VoIP services are being embraced by consumers worldwide, businesses have been comparatively slower in their adoption due to various roadblocks,” said Matthias Machowinski, enterprise voice directing analyst, in a statement announcing the findings. “This is about to change, though, as technical issues are resolved.”
