Disclosed are systems and methods which provide a centralized architecture for call
processing. Embodiments utilize voice over Internet protocols (VoIP) to carry calls from a location at which calling services are provided to a centralized call
processing platform providing call
processing functionality, such as calling party identification, call validation,
call routing, and connection to the public switched
telephone network (PSTN). Call processing gateways may be utilized to provide
plain old telephone service (POTS) analog line interfaces for use with a plurality of telephone sets disposed for use at a location and at least one
wide area network (WAN) interface for providing high speed data communication to a centralized call processing platform. PSTN
interfacing by a call processing platform may be provided as a VoIP connection to the PSTN and / or as POTS
trunking. Call processing platforms may provide for
data sharing, aggregation, and / or analysis across multiple facilities served.
