For Immediate Release: August 10, 2017

WESTFORD, Mass. – Sonus Networks, Inc. (Nasdaq: SONS), a global leader in securing cloud and real-time communications, announced today that Miercom, an independent certification company, has verified the performance and security of the Sonus SBC 5400 Session Border Controller (SBC). With this certification, customers can enjoy peace of mind knowing the Sonus SBC 5400 delivers proven security, reliability and performance in the most demanding network conditions.

The SBC 5400 was purpose-built to meet the unique real-time communications challenges large enterprises and service providers face today. As these customers migrate from legacy to next-generation IP-based communications systems, the Sonus SBC 5400 provides a solution for robust network security, intelligent session control, robust media services and SIP normalization.

The Miercom report found the SBC 5400 delivered impressive results during multiple tests and attack scenarios, including the ability to provide:

  • Advanced Scalability – The capacity of the SBC 5400 hardware platform can be easily expanded to 75,000 concurrent sessions by simply upgrading media interface capacity via software licensing.
  • Unparalleled Performance – While many competitive SBCs lose as much as half their call capacity by encrypting VoIP media streams, the SBC 5400 easily supports just as many encrypted secure RTP sessions as normal unencrypted media sessions.
  • Robust Security – Denial of Service (DoS) flood attacks were launched at the SBC 5400’s SIP-signaling and media ports while it handled high call volumes. The SBC 5400 effectively deflected these attacks and no legitimate calls were dropped irrespective of call complexity.

With this certification, the entire Sonus SBC Core portfolio is now Miercom Performance Verified. Miercom’s certification of Sonus’ performance in extreme network conditions gives customers the assurance they require as they migrate to next-generation IP-based communications systems.
