VOSS is able to provide business orchestration because it creates logical business entities such as ‘customer’ and ‘location’. These business entities are not the same as the locations created within a network element; e.g. location within an IP-PBX is just a group of devices and users. Instead, VOSS builds locations to contain business relevant data such as IPT resources, network, dial plan, numbers, services, etc.
VOSS also abstracts business data from the network and links this with logical business entities. A good example of this is the concept of hardware groups and call planner groups. VOSS maps the infrastructure elements across the network, but then creates virtual groups of infrastructure that relate to each location.
This means that VOSS knows the relationship between each location and what gateway it will use, what voicemail platform it will use, what IP-PBX it will use, what conference server it will use, and so on. In addition, VOSS also links each virtual hardware group to a call planner group, which contains all the information about the dial plan for that location.
