Case study: BT uses open source BI to support its voicemail system

BT has deployed open source software to support its voicemail system, which currently serves around eight million UK customers.

With the help of systems integrator Unisys, the telco deployed Jaspersoft ’s open source business intelligence (BI) software in its statistical data warehouse (SDW) around 18 months ago, following an initial six-month development project around the source code.

About 50 employees currently use Jaspersoft to query and report on data stored in BT’s vast voicemail database. Staff can analyse mailbox and message counts by class of service, service provider, and usage level and frequency, for example, and produce and distribute reports quickly and easily in multiple formats, which include PDF, Excel, Word and CSV.

This has helped the telco reduce the time it previously took to research and respond to its voice mail customer queries, and to lower the cost of producing ad hoc reports that were previously available only either in standard, daily formats or obtained by submitting a special request to Unisys.
