The Paisley Group, an independent auditor of directory assistance, toll assistance and relay services, has rated VoltDelta’s (News - Alert) U.S. directory assistance database as being 99.75 percent accurate, meaning that it is one of the most accurate DA databases in the country.

In this year’s audit, VoltDelta’s U.S. directory assistance database, which is comprised of millions of names, addresses and localities for business, government and residential listings, exceeded the industry average of 98.3 percent accuracy for 2009. Accuracy was measured for listings requested from operators across the U.S. in November.

This is a significant accomplishment considering that the data used for compiling such databases comes from multiple sources and must be properly compiled and 'scrubbed' in order to provide complete and accurate listings.

Key to achieving this high degree of accuracy is VoltDelta’s web-based system, which makes it easy for telecommunication and VoIP providers to report disconnected or missing listings. As a result, VoltDelta Data Quality team members are able to react more quickly to resolve issues that might appear within the directory assistance database.

“VoltDelta’s 99.75 percent mark for accuracy stands in testament to an organization dedicated to persistent optimization,” said Jeff Rudolph, president and CEO of the Paisley Group, in a release.

Terry Saeger, SVP and GM of VoltDelta’s Directory Assistance, OnDemand and LSSiDATA divisions, said “Paisley Group audits for the past three years have verified VoltDelta accuracy with consistent year over year improvement.”

“We will continue to work to deliver listings excellence for our telecommunication customers as well as extend the value of our unique database resources to enterprises seeking to add personalization for customer care efforts,” Saeger said.

VoltDelta, which sponsors the Call Center Solutions channel on TMCnet, made news last week when it announced that BT (News - Alert), one of the largest providers of phone and Internet service in the world, is now using Volt Delta’s (UK) hosted call center solution, OASIS, for its operator services in the United Kingdom -- including its national 999 emergency call handling service.

In addition, BT is using OASIS for its directory assistance services, including 118500, and other operator assistance services such as its alarm and reminder services. The carrier will also use the solution to support a range of wholesale services.

The company’s LSSiDATA (News - Alert) division made news back in October when it announced that it had launched a new Website for customer data supplements, new mover identification and rapid refresh information at LSSiDATA.com.

According to a press release, content features span core data statistics for hundreds of millions of customers and businesses, the use of unique algorithms for interactive database access, and ranges of data sources.

'LSSiDATA stands out by delivering the most up to date enriched consumer and business data that reaches beyond typical directory information,' Saeger said at the time. 'The new website will allow those organizations providing marketing reach, customer care and e-business solutions to better evaluate how they can achieve a competitive advantage with LSSiDATA.'

Using LSSiData, directory assistance providers have fast access to customer data including name, addresses and phone number. The service is enhanced with rich LSSIData sources -- such as a geo-location for wireless callers, publically derived creditor indicator and contact information for those accessing VoIP services. Robust LSSiData processes and exceptional quality standards drive an expansive daily refresh, which is remarkably adept at identifying new movers.

Additional characteristics aggregated from new connect sources, CLECs, wireless numbers, opt-in email addresses, VoIP users and other non-published listings form the foundation of LSSIDATA’s differentiated data repository.
