 Active Approach for Revenue Generation

Oi is the major Brazilian telecommunications operator in revenue with over 29 million subscribers and is ahead of the market, merging fixed and mobile telephony, broadband internet and entertainment in its strategic approach of service convergence.

Oi has been working with Teradata since 2004 to design cost-effective solutions for complying with a growing number of Brazilian telecommunications regulation directives that affect Oi's revenue assurance and in-service performance indicators. Oi increased their results due to CDR X SS7 verification for revenue assurance. Also a conciliation of interconnected call against billed call is another application of high business value.

In 2007 the latest regulator's directives change how calls are recorded for billing purposes (from pulse metering to time metering), Oi is using Teradata to ensure that the company's bottom line is not impacted and remains healthy.
