Chapter 2 Provisioning Overview Target Market The applications and devices described in this document are positioned for service provider scale, VoIP networks. Although many of the applications can be deployed in enterprises and smaller scale networks, the solution suite referred to in this Solution guide is aimed at the large carriers and providers of VoIP network bandwidth and services. It also concentrates on the devices deployed in a VoIP network, although non-VoIP devices integral to t

Chapter 2 Provisioning Solution Architecture Virtual Entities in the Network The requirements for coordinated element management are extensive. For instance, the media gateway and MGC must be synchronized regarding the voice endpoints. Although the MGC has a concept of a trunk, this concept is unknown to the media gateway that has the actual resources (TDM endpoints, ports) that constitute the trunk. Therefore, the knowledge that both the media gateway and the MGC have of the trunk must be
