Secure Your Network
The SBC controls the admission of calls in and out of the enterprise and protects the network against Denial of Service (DoS) attacks, toll fraud, and other attacks against the Skype for Businuess Enterprise Voice network. Additionally, the SBC can "hide" the topology of the Skype for Businuess network within the enterprise, so external parties aren't able to detect the devices within.
Maximized Resiliency and Protection Against Attacks
Keeping the "lights on" is important in any network environment. In an Enterprise Voice environment, it's critical. Sonus SBCs are designed to provide high availability, enabling calls to be completed even under peak conditions. For larger deployments, Sonus SBCs can be deployed in pairs (in what's called Active-Active mode) to provide load balancing and even high availability. Sonus SBCs can additionally balance the call load across multiple Skype for Businuess Mediation servers, to keep the network up no matter what. Resiliency can really come into play when a network is compromised by a DoS attack. Such an attack can cripple an enterprise's voice services by simply overloading servers with malicious incoming IP traffic. Sonus SBCs offer sophisticated real-time firewalling and the use of techniques such as Virtual LAN (VLAN) tagging, which drops the malicious packets and allows legitimate traffic to continue on to the network unimpeded. So the enterprise stays online and productive!
Keeping sensitive enterprise conversations away from eavesdroppers is the role of encryption in an Enterprise Voice deployment. The SIP standard itself uses plain text signaling, so nefarious parties on the Web may be able to intercept a SIP-based call. With a Sonus SBC and its support for AES encryption (128-bit), potential eavesdroppers aren't able to make heads or tails of a conversation they might be able to otherwise listen in on. And Sonus' SBC architecture — which separates encryption processing tasks to their own processor architecture within the SBC — allows real-time encryption processing to take place without causing slow-downs in other SBC functions, such as call routing or media processing.
