Abstract
A virtual private branch exchange is formed by a plurality of interconnected feature server modules, each having an integral feature server that is configured and operates independently of the other feature server modules. Within a virtual private branch exchange, the feature server modules may be logically arranged in a hierarchy having at least a main feature server module and one or more subordinate feature server modules. A particular feature server module may operate in multiple virtual private branch exchanges, and may have a distinct set of rules for handling calls originating in different virtual private branch exchanges.
