Sonus Harmony Architecture Introduced at ITEXPO Austin 2012

Today at ITXPO Austin 2012, Sonus Networks (News - Alert) unveiled its Sonus Harmony Architecture. A SIP-based applications delivery and network unification architecture, Harmony coordinates different communication elements – PBX (News - Alert), communication applications and collaboration tools – to create a unified communications environment.


The Harmony Architecture relies on the session layer, enabling a neutral session management capability that doesn't particularly rely on any specific access or application layer component.

Indeed, Sonus Harmony relies on many technologies, such as Sonus Session Manager and Sonus Composer.

Sonus Session Manager is able to tie together these disparate infrastructures by way of PBXs and endpoints customers already have. In other words, this session management enables both call setup and takedown, as well as user authentication and registration, application sequencing, and rich SIP adaptation.

The Sonus Composer Software Development Kit (SDK), meanwhile, works at the application layer. Comprised of a broad set of scripts, adapters and APIs, Composer allows Java and Web designers to rapidly integrate, develop and deploy new applications via Session Manager. While not an application provider itself, Sonus' ecosystem of application partners, Sonus Plus, is offering applications that are pre-integrated and tested with Session Manager.

The Sonus Plus program provides both developer tools and training to ecosystem partners, along with a developer 'sandbox' for testing and certifying apps prior to integration with Session Manager.

Lastly, at the access layer, Sonus Harmony provides policy enforcement, call control, message manipulation, signaling interworking, TLS/security, media services and transcoding.

Sonus Networks is dedicated to helping communications service providers and enterprises embrace the next generation of SIP-based solutions. The company is currently participating in ITEXPO (News - Alert) Austin in Austin, Texas, and is a Platinum Sponsor of the event.

Sonus president and CEO Raymond P. Dolan made a keynote address at ITEXPO earlier today. TMC's Paula Bernier (News - Alert) covered it here.

Recently, Sonus Networks was presented with the 2011 Communications Solutions Product of the Year Award by TMC for the company's PSX Centralized Policy and Routing Server.


Sonus Networks is a Platinum sponsor of ITEXPO Austin 2012. Happening now at the Austin Convention Center in Austin, TX, ITEXPO is the world’s premier IP communications event. Visit Sonus Networks in booth # 901. Mykola Konrad, director of Enterprise Product Management, and Raymond P. Dolan, president and chief executive officer, will be keynote speakers at the event.

The Evolution of Session Border Control
Session Border Controllers have come a long way since they were first conceived in the early 2000s as a simple, security-focused element. As service providers and enterprises began deploying more advanced real-time applications over IP-including Unified Communications, video, instant messaging, and conferencing-the burden on SBCs grew in step.

The ABCs of PCI DSS + VoIP
As the boundaries between VoIP and IP-based data networks continue to blur, enterprises would be wise to apply the same levels of network security across all entrypoints. Session border controllers are designed to protect VoIP network borders from unauthorized entry, but not all SBCs are created equal in terms of security features and functionality.
