Report: SIP trunking drives 70% jump in enterprise session border controller market

May 15, 2011

"Enterprise session border controller revenue jumped 70% worldwide in 2010 off the continued adoption of SIP trunking services. In our recent SIP Trunking Strategies survey of North American enterprises, 43% of respondents said they are using SIP trunks in some capacity, although they are not completely displacing PSTN connections. All indications show that as businesses upgrade their voice infrastructure, they are making the move to SIP trunking, which will continue to drive growth of enterprise SBCs," expects Diane Myers, directing analyst for VoIP and IMS at Infonetics Research.


  • The use of SIP trunking is growing, and more respondents use it than ISDN PRIs already, but legacy technologies are not disappearing any time soon (T1 lines are still the most commonly used trunking service today, and will be in 2013)
  • Flexibility, easier management, and infrastructure upgrades top the list of reasons businesses are deploying SIP trunking
  • Cisco leads the list of PBX manufacturers under evaluation for future purchases, followed by Avaya
  • The presence of IBM and Microsoft in the top 4 installed PBX manufacturers demonstrates the growing adoption of unified communications (UC)
  • The market is wide open in terms of SIP trunking providers, with enterprises using and evaluating AT&T, Verizon, smaller incumbents, cable operators, competitive carriers, and over-the-top (OTT) providers, illustrating the current competitive landscape for SIP trunking


Report: $74.5B VoIP services market by 2015, 2010 was a breakout year for SIP trunking

May 1, 2011

The crippling economic downturn of the past several years slowed growth in the VoIP and UC services and subscribers market, but increasing customer uptake, especially in the business segment, has fueled a solid comeback, according to a new report.

Infonetics Research said the VoIP service market reached $49.8 billion in 2010, a 43 percent increase from $34.8 billion in 2008, and forecast the the combined business and residential/SOHO VoIP services market to grow to $74.5 billion in 2015.

The company said the residential services segment remains the largest of the market at 69 percent of total revenue, but added that business VoIP services are growing at faster rates.

A highlight for 2010, Infonetics said, was the 143 percent revenue growth in SIP trunking.
