This specification defines the requirements for the PacketCable 2.0 Enterprise SIP Gateway (ESG)
device. The primary purpose of the ESG is to simplify and streamline the initial deployment and ongoing
management of Business Voice services to enterprise customers. The ESG sits at the boundary between
the Service Provider and Enterprise network and serves as a demarcation point between these two
networks. It normalizes the wide variety of SIP (Session Initiation Protocol) signaling protocols supported
by currently deployed enterprise CPE (Customer Premises Equipment) equipment into a single welldefined interface that is compatible with the PacketCable network. It also provides enhanced fault
detection and reporting capabilities that speed up the detection, isolation, and resolution of serviceaffecting failures. Finally, the ESG can act as a Gateway device for provisioning traffic between the
Service Provider network and operator-owned and managed Enterprise CPE equipment.
