A method for implementing a telecommunications service delivery platform in multiple locations, comprising: locally implementing a service delivery platform extension, comprising: a subscriber user interface component; a service metering component; a core service delivery platform interface component; and a local service orchestration component comprising an enterprise service bus in communication with the subscriber user interface component, the service metering component, and the core service delivery platform interface component; generating a local service provisioning interface on the subscriber user interface component; receiving a subscriber service provisioning request for a telecommunication service through the subscriber user interface component; communicating the subscriber service provisioning request through the local service orchestration component to the core service delivery platform interface component; communicating a telecommunications service provisioning message, through the core service delivery platform interface component, to a web services interface of a remote core service delivery platform, which implements service provisioning to fulfill the service provisioning request, wherein the core service delivery platform is located remotely with respect to the service delivery platform extension; and locally metering, using the metering component, telecommunications service calls flowing through the service delivery platform extension and arising from the telecommunication service, wherein the service delivery platform extension duplicates a support message corresponding to each of the telecommunications service calls, wherein a first copy of the support message routes through the core service delivery platform interface component to the remote core service delivery platform to fulfill the service provisioning request, and a second copy of the support message is used for locally metering the telecommunications service calls. locally implementing a service delivery platform extension, comprising: a subscriber user interface component; a service metering component; a core service delivery platform interface component; and a local service orchestration component comprising an enterprise service bus in communication with the subscriber user interface component, the service metering component, and the core service delivery platform interface component; a subscriber user interface component; a service metering component; a core service delivery platform interface component; and a local service orchestration component comprising an enterprise service bus in communication with the subscriber user interface component, the service metering component, and the core service delivery platform interface component; generating a local service provisioning interface on the subscriber user interface component; receiving a subscriber service provisioning request for a telecommunication service through the subscriber user interface component; communicating the subscriber service provisioning request through the local service orchestration component to the core service delivery platform interface component; communicating a telecommunications service provisioning message, through the core service delivery platform interface component, to a web services interface of a remote core service delivery platform, which implements service provisioning to fulfill the service provisioning request, wherein the core service delivery platform is located remotely with respect to the service delivery platform extension; and locally metering, using the metering component, telecommunications service calls flowing through the service delivery platform extension and arising from the telecommunication service, wherein the service delivery platform extension duplicates a support message corresponding to each of the telecommunications service calls, wherein a first copy of the support message routes through the core service delivery platform interface component to the remote core service delivery platform to fulfill the service provisioning request, and a second copy of the support message is used for locally metering the telecommunications service calls.
