SIP Trunking is on the rise – particularly in North America. A recent study showed that SIP trunking jumped 23 percent during the first half of this year compared to the second half of 2012.
The Infonetics Research study showed that worldwide residential VoIP subscribers in the first half of 2013 totaled more than 203 million.
“The VoIP services market is on track with our expectations for 2013,” Diane Myers, a VoIP, UC and IMS analyst at Infonetics Research, added in a statement from the research firm. “Residential VoIP services make up the majority of revenue, but growth is being fueled by business services as SIP trunking and cloud unified communications continue to expand and find broader adoption with enterprises of all sizes.”
The study contained in the VoIP and UC Services and Subscribers report also showed worldwide business and residential revenue for VoIP services edged up 3 percent to $33 billion during the first half of 2013.
Looking ahead, business VoIP service revenue is predicted to increase some 7 percent globally in a compound annual growth rate between 2012 and 2017, Infonetics Research said. That is higher than the 3 percent CAGR for residential/SOHO (small office and home office) VoIP services.
It was also noted in the study that hosted PBX/UC (private branch exchange, Unified Communications) increased more than any other VoIP service in the first half of this year. It appears larger enterprises and other businesses are using more hosted services instead of premises-based solutions, Infonetics Research said.
Other recent studies have shown that 13 percent of businesses now use SIP for all of their wide area network (WAN) traffic. The same Eastern Management Group (EMG) study added that 42 percent of businesses will send all toll traffic on SIP trunks by 2018.
