Recently industry observer Ian Mansfield wrote that Infonetics (News - Alert) Research forecasted the combined business and residential/SOHO VoIP services market to grow to $76.1 billion in 2015.

According to Infonetics officials, the three leaders of the global residential VoIP services market -- NTT, Comcast (News - Alert), and France Télécom -- continue to add new VoIP subscribers in their respective regions.

“Revenue from SIP trunking services to businesses is forecast by Infonetics to grow at a phenomenal 52 percent compound annual growth rate (CAGR) from 2011 to 2015,” Mansfield wrote, adding that “due to continued demand for cloud-based services, IP Centrex and hosted unified communication service revenue grew 22 percent and seats grew 25 percent in the first half of 2011 compared to the second half of 2010.”

Recently, Visiongain (News - Alert) reported that the mobile VoIP market is expected to grow at a compound annual growth rate (CAGR) of 17.6 percent over the next five years to reach $36 billion in revenues by 2016. The report predicted that by the end of 2011, there will be around 70 million mobile VoIP users, according to [http://www.tmcnet.com/channels/ip-softswitch/articles/226034-voip-services-market-cross-76-billion-mark-2015.htm] TMC’s Rajani Baburajan.

Diane Myers, directing analyst for VoIP and IMS at Infonetics Research (News - Alert), said the residential segment “continues to make up the majority of VoIP services revenue, but the real growth is in the business segment, particularly SIP trunking services and hosted VoIP and unified communication services," according to Infonetics officials, who noted that 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.

As Myers noted, “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.”
