The upcoming chapters will describe how OpenScape 4000 covers general
Session Border Controller specifications.
The first chapter presents general Session Border Controller specifications
gathered via Wikipedia as source information.
The Built-in SBC Function chapter is referring to these general Session
Border Controller requirements and describes how these are realized in

and SoftGates virtual HGs).
