Aura SBC

Problem Statement
 Enhanced security is required to protect the Enterprise network

TechShare Conference 2010
We make it possible. So you can make it happen

 Disparate VoIP and UC systems may not interoperate properly
– – –

Different software revisions from the same vendor Different vendor systems Different protocols (e.g. SIP and H323)

 Ensuring quality and reliability over IP trunks needs careful planning

 Meeting regulatory compliance mandates can be difficult and costly


Quick fixes can be inefficient, inflexible and difficult to manage

Session Border Controllers help solve these problems
