Company connections to the public voice network are referred to as SIP trunks. Depending on a customer's requirements in terms of throughput, security and availability, the design and implementation of a SIP trunk can differ from provider to provider.The result is frequently recurring error patterns. A session border controller (SBC) plays an important role at the interface between customer and provider. The special features as well as the numerous variants of a SIP trunk are analyzed in detail in this SIP trunking course and examined using practical exercises.
