eSBC market grows 60%, pushed by SIP trunking uptake


SIP trunking adoption is continuing to push the Enterprise Session Border Controller (eSBC) market, according to new research, appealing to the demand from enterprises for security, interoperability and network border traversal.

Infonetics Research said SIP trunks grew 88 percent in 2011 over the previous year and added that the increase is fueling eSBC sales so much that it now forecasts will reach $527 million globally in 2016.

"The market for enterprise session border controllers jumped 60 percent in 2011 and will grow significantly over the coming years as the adoption of SIP trunking continues to expand," said Diane Myers, directing analyst for VoIP and IMS at Infonetics. "The enterprise SBC market is a sweet spot in the enterprise market because they fill a growing need for security, interoperability and network border traversal."

The largest eSBC market remains in North America, Infonetics said, though its majority share is likely to shrink as other regions increase SIP trunking adoption, Myers said. Acme Packet (Nasdaq: APKT) and Cisco (Nasdaq: CSCO) were the top two vendors in the space, chased by competitors Adtran (Nasdaq: ADTN), AudioCodes, Avaya, Dialogic (Nasdaq: DLGC) and Edgewater, among others.
