Top 10 Reasons to Choose Sonus Enterprise SBCs

The cost advantages of SIP trunking and the need for secure SIP session management are driving more enterprises to implement Session Border Controllers (SBCs) in their network.
By: Advantage Technologies

How can an enterprise be sure that the SBC solution they’re buying is a true enterprise-ready solution and not simply a carrier SBC solution with fewer sessions? By measuring the SBC’s performance in a real-world enterprise environment: frequent SIP interworking, heavy encryption workloads, media transcoding, interworking with a mix of legacy PBX systems and a growing need to interconnect IPv4 and IPv6 devices.

With that in mind, here are the top 10 reasons why Sonus SBCs work better in the enterprise:

1 Interoperability with Legacy TDM/H.323 Systems Sonus SBCs support both TDM and IP traffic in the same device, with hot-swappable circuit- and packet-switched processors that allow enterprises to migrate from TDM-IP to all-IP traffic at their own pace. Sonus SBCs also provide legacy PBX interworking with simultaneous support for TDM, H.323 and SIP PBXs.
2 Robust SIP Interoperability SIP interoperability is a requirement for enterprises that need to interconnect different IP PBX boxes, multivendor VoIP switching equipment, SIP trunking services, IP-based Interactive Voice Response (IVR) systems, etc. Sonus SBCs provide robust SIP interworking, offering both dynamic and static SIP normalization between a multitude of enterprise IP devices.
3 High Performance During Overload/Attack While many SBCs perform well under ideal conditions, the Sonus SBC’s unique multiprocessor design demonstrates high performance even during overload/attack conditions. A recent Miercom performance study found that the SBC 5200 performed 400% better than the leading competitor during overload conditions, and confirmed in a simulated spoofing attack that “there was no observed impairment of active calls sustained or failure to place new calls while under attack conditions.”
4 High Availability/Disaster Recovery Enterprise communications require 99.999% availability and reliable disaster recovery provisions. Sonus SBCs are engineered to provide ultra-high reliability through a redundant active/standby architecture that ensures the system has no single point of failure. Sonus SBCs also demonstrate rapid recovery after power outages. In a recent Miercom test, the Sonus SBC 5200â„¢ re-registered IAD endpoints after a simulated system outage 8x faster than the leading competitor.
5 Near-Linear Scalability Both the Sonus SBC 5200 and SBC 9000′” Session Border Controllers provide near-linear scalability to handle millions of subscriber sessions. This scalability stems from Sonus’ heritage in building network solutions for the world’s largest carriers, resulting in a Sonus architecture that is practically limitless.
6 Rapid Deployment The Son us SBC 5200 delivers rapidly deployable plug-and-play functionality in a pure IP appliance form factor. An SBC 5200 can be installed in an enterprise network and “turned on” in less than two hours.
7 Pv4/IPv6 Interoperability With the imminent exhaustion of IPv4 addresses, the world will soon transition to IPv6, creating the need for IPv4 and IPv6 devices to communicate with one another. Sonus SBCs provide flexible IPv4-to-IPv6 interoperability so legacy devices and new IPv6-enabled devices can communicate seamlessly.
8 Centralized Policy Management When it comes to policy control, Sonus SBCs give enterprises a choice: a local embedded routing and policy engine for standalone deployments, or a centralized policy engine via the PSXâ„¢ server. Both configurations have their advantages: the Embedded PSX (E-PSX) can provide lower latency, while the centralized policy server provides multi-SBC deployments with tremendous cost and time savings through simplified provisioning management.

How Does the Sonus SBC Stack Up

Against the Competition?

9 Built-In Media Transcoding Transcoding between media codecs is increasingly important to enterprise communications, especially as more enterprises look to support a variety of high-definition (HD) voice codecs. Sonus SBCs have always featured built-in media transcoding, which results in better call quality and more efficient processing of calls that require codec translations between both HD and non-HD devices.
10 High-Performance Encryption Enterprise VoIP networks require strong security measures to protect both internal and customer communications and information. Sonus SBCs provide industry-leading security features, including TLS, SRTP and IPsec encryption, B2B User Agent functionality for topology hiding and much more. While many SBCs offer similar security features, Sonus SBCs have built-in encryption hardware and dedicated processors to encrypt media and signaling information, which results in very little impact on SBC performance even when 100% of calls are encrypted.
