Two recent Infonetics Research studies found that voice over IP through SIP trunking service is growing rapidly in the United States.

According to Infonetics' VoIP service and unified communications adoption grew 16 percent in 2011, while demand for cloud-based services also drove up hosted PBX revenue by 33 percent.

This growth, which ranges from simple VoIP adoption to complex UC solutions, shows that many businesses are realizing the benefits they can gain from looking into telecommunication and collaboration services. Additionally, using SIP trunking for its flexible and cost-effective protocol has grown over 128 percent from 2011 to 2010, with even more adoption expected soon. According to a second Infonetics survey, SIP Trunking and Enterprise SBC Strategies, around 42 percent of all businesses in North America anticipate using SIP by 2014. Currently, T1 lines are the most popular trunking method for making VoIP calls.

While residential voice service has been gaining in popularity, business VoIP phone system adoption is expected to grow about twice as fast, with "strong global growth in VoIP service revenue over at least the next five years," said Diane Myers, a VoIP and IMS analyst for Infonetics Research.
