A reasonable person might argue that access services are driving the IP telephony market. Revenue from SIP trunking services to businesses, for example, is forecast by Infonetics Research to grow at a 52 percent compound annual growth rate from 2011 to 2015. Hosted IP telephony might grow at about a 22 percent rate over that same time frame.
“We’ve increased our short- and long-term forecasts for the voice over IP services market, as adoption in the residential, SOHO, and business segments continues unabated,” says analyst Diane Myers.
Consider that the overall VoIP services market will grow 17 percent in 2011,” says Myers.
Infonetics Research forecasts the combined business and residential/SOHO VoIP services market to grow to $76.1 billion in 2015.
The number of seats for hosted business VoIP and unified communications services is on track to more than double between 2011 and 2015, she notes.
IP Centrex and hosted unified communication service revenue grew 22 percent in 2010 and seats grew 25 percent in the first half of 2011 compared to the second half of 2010.
The number of residential and small office/home office (SOHO) subscribers to hosted VoIP services is expected to grow from 179 million in 2011 to 262 million worldwide by 2015, says Myers.
