Nearly Three Out of Four Companies Have Adopted UC As SIP Usage Rapidly Expands

The Requirements and Benefits of Deploying Session Border Controllers for Real-Time Communications Also Grows

January 6, 2015, Westford, MA – Sonus Networks, Inc. (Nasdaq: SONS), a global leader in enabling and securing real-time communications, today announced the results of a new report entitled “2014-2015 Unified Communications, SIP, and SBC Plans and Priorities: What’s Hot and What’s Not,” indicating that the adoption of Unified Communications (UC) continues to increase, with a major shift toward UC solutions being implemented via SIP. Furthermore, results of this study show that there is a clear indication that Session Border Controllers (SBCs) are expected to be the enabling technology that provides the necessary interoperability, security and reliability for a highly functional network.

“2014-2015 Unified Communications, SIP and SBC Plans and Priorities”

The report was conducted by the independent Webtorials Editorial and Analyst Division and underwritten by Sonus. This report mirrors the “2012 Mobile Unified Communications State-of-the-Market Report,” conducted by Webtorials, and offers a unique comparison on how the SIP trunking market has influenced the adoption of UC and SBCs over the past two years.

Key highlights include:

  • The percentage of respondents who had either partially or fully deployed UC solutions has moved from 68% to 72% with the balance of respondents largely in or soon be in the planning phase.
  • Roughly seven out of ten UC and enterprise voice deployments are premises-based, though this figure is projected to drop as more future deployments move to the Cloud. According to the study, hybrid deployments are the preferred approach to UC in the future.
  • Respondents continue to indicate a desire to move from proprietary to standards-based solutions, although the movement toward that goal is not happening rapidly.
  • The biggest change since the 2012 study was the increase in the use or planned use of SIP for various functions.
  • As an integral component to secure and enable the real-time features of UC, the functions of SBCs are becoming much more recognized, with an increase from 14% to 25% among respondents who claim to be extremely familiar with these capabilities. The primary reason cited for SBC deployment is security, while ensuring a high quality of service also shows great importance.

“The ‘2014-2015 Unified Communications, SIP, and SBC Plans and Priorities’ report shows that two years later, enterprises continue to seek the advantages that come along with unifying their communications,” said Steve Taylor, editor-chief and publisher for Webtorials. “The shift we are seeing in UC today, however, is the move toward SIP-based solutions, future plans to move to the Cloud, and the understanding of importance that Session Border Controllers bring to securing real-time communications.”

“We’ve seen Unified Communications evolve from voice and video, to incorporate real-time collaboration tools which improve productivity. The explosive growth among enterprises implementing SIP Trunking has further enabled the ability to knit together previously disparate technology platforms,” said Wes Durow, vice president of Global Marketing, Sonus. “When deploying these new communications services, the ability to leverage Session Border Controllers improves the security, interoperability, and quality of service challenges often faced when working across multi-vendor networks.”

Other Facts:

  • This study mirrors a study Webtorials performed in December 2012, also underwritten by Sonus, surveying IT professionals in organizations with more than 1,000 employees to determine their plans and priorities for UC as well as their attitudes toward the inextricably linked SIP and SBCs.
  • Sonus was positioned in the Leaders Quadrant of the “Magic Quadrant for Session Border Controllers,” published October 21, 2013 by Gartner, Inc.
