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

"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.

SIP TRUNKING SURVEY HIGHLIGHTS

• 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
