The global VoIP services market, including residential and business VoIP services, reached $63 billion in 2012, up 9 percent from 2011.
Due to continued demand for enterprise cloud-based services, hosted VoIP and UC services revenue grew 17 percent in 2012 from 2011, the most of any segment.
SIP trunks rose 83 percent in 2012 from the previous year, as multi-site businesses adopt SIP trunking for cost savings and flexibility.
Managed IP PBX services, which focus on dedicated enterprise systems, remain the largest business VoIP services segment, and sales grew 9 percent in 2012.
“The market for VoIP services has moved well beyond the early adopter stage to mainstream status in many developed countries. New geographic regions are opening up, and SIP trunking and hosted UC continue to heat things up, fueling growth,” said Diane Myers, principal analyst for VoIP, UC, and IMS at Infonetics Research.
Vendors are pitching cloud telephony and unified communications services alongside SIP trunking as more multi-site businesses seek out hybrid solutions.
