The autocall system decodes vendor diagnostic data from platforms including Network Appliance, IBM, EMC (VMAX, VNX, Clariion, Celerra), Linux, Solaris, Dell, Cisco, HP, Brocade, Hitachi, VMware, and Microsoft. Multiple transports are provided: diagnostic data may be delivered via email, ftp upload, SNMP trap, WMI probe, or web page; command-line tools and third-party integration are supported via web-service API.

Once received, the vendor data is refactored into a human-readable "generic chassis" (example here), and the hardware inventory (if supplied) is dissected into a collection of parts associated with the chassis. An extensible notification mechanism is provided as a means to integrate existing entitlement verification and ticketing systems; any reported hardware failures can generate real-time alerts. The original data is then archived for possible future analysis.

A web interface allows ad-hoc browsing of the inventory history database, including both broad searches (summary of platform types, total site installation, etc.) and queries on specific chassis serial numbers. This data can also be analyzed to detect configuration changes and predict possible future failures, distilled into a table of "unique pieces" for spares provisioning, or summarized into asset management and lifecycle reports.
