For Immediate Release: July 9, 2014
Key Takeaways:
 Increased session and port capacity on the SBC 1000 and SBC 2000 Session Border
Controllers (SBCs) can now be activated via a license key, removing the need for
technician-assisted installation of additional hardware.
 Sonus is the only SBC vendor enabling session and port capacity on branch office SBCs to
be upgraded using software without the requirement of hardware upgrades, thereby
reducing upgrade expenses and service disruptions.
 The new capabilities of the SBC 1000 and SBC 2000 enable resellers to better serve end
customers while reducing operational expenses or deploying additional field personnel.
WESTFORD, Mass. – Sonus Networks, Inc. (Nasdaq: SONS), a global leader in SIP
communications, today introduced new software and hardware enhancements to the Sonus
SBC 1000 and SBC 2000 Session Border Controllers (SBCs) which provide customers greater
investment protection by enabling increased session and port capacity in a quick, simple
manner. With the continued rapid growth of new real-time communications applications such as
Microsoft Lync Enterprise Voice, there is a corresponding demand for more session throughput
in customer deployments. Today’s announcement simplifies how enterprises – and the resellers
who support them – can scale session capacity to meet the needs of Voice over Internet
Protocol (VoIP), video and other latency-sensitive collaboration tools associated with Unified
Communications (UC) deployments.
With the introduction of Release 3.2, increased session and port capacity on the SBC 1000 and
SBC 2000 can now be activated remotely with a license key, removing the need for technician-
assisted installation of additional hardware. The flexible architecture of the SBC 1000 and SBC
2000 allows service providers, resellers and enterprises to quickly add capacity without the
inconvenience of service disruption. Sonus is the only brand to offer such ease-of-use capability
in a branch office SBC portfolio.

2. As workplace communications increasingly take place outside of formal office locations, Session
Initiation Protocol (SIP)-based communications have become foundational as companies strive
to deliver the same capabilities regardless of where an employee works. SBCs serve a critical
role in securing and enabling disparate technologies across service provider and enterprise
networks to work together seamlessly so that Microsoft Lync and similar collaboration platforms
can deliver real-time communications such as VoIP, video, presence, unified messaging, find
me/follow me, virtual whiteboarding and document sharing. By integrating Sonus SBCs into
real-time communications deployments, these powerful network devices protect, secure,
simplify and standardize what otherwise would be very complex SIP-based multimedia
communications.
By helping customers future-proof their networks without over- or under-subscribing to session
or port capacity at the time of deployment, the new configurations of the SBC 1000 and SBC
2000 address today’s dynamic business environments. Customers can purchase the capacity
they need today with confidence that increased session and port count can be added in
minutes, instead of hours or days, through the use of a software license key. The expanded
control over network growth empowers service providers and enterprises to simplify network
design, reduce costs and more effectively deploy advanced real-time communications features.
The Sonus SBC 1000 and SBC 2000 are integrated into the Sonus Element Management
System (EMS), delivering one common network management solution across the complete
Sonus SBC product portfolio. This release amplifies EMS functionality on the SBC 1000 and
SBC 2000 with support for network-wide provisioning, scheduled backup/restore and scheduled
updates to help customers reduce operating costs, optimize investments and maximize network
performance.

general manager, SBC Business, Sonus. “With Release 3.2 of the SBC 1000 and SBC 2000,
