VNFs

Service Control Function (SCF) Virtual Network Function (VNF) redirects the mobility call to MCR.

Recording VNF records the call under the direction of the Cloud Foundry (CF) customer app.

The CF VNF runs the customer apps (written in node.js) which integrate with the Recording Processor (RP) VNF.

RP VNF delivers the metadata (calling/called numbers, etc) and recording to customer storage immediately after the call.

Some per customer app customizations include: Recording disclaimer; Reminder tone; Reminder interval & URLs and credentials for the storage provider

AT&T has already transformed 5% of our targeted network with a goal of 30% in 2016 onto our SDN enabled cloud

Domain 2.0 is a transformative initiative to enable AT&T network services and infrastructure to be used, provisioned, and orchestrated as is typical of cloud services in data centers by leveraging SDN, NFV and Orchestration.
