2. Case Study - I Solutions for RA Monitoring of Carrier Margins in a major Global Carrier • Designed, built and implemented solutions to monitor carrier margins and traffic profiles, utilising call records generated by network probes and other aggregated data, for a Global Carrier. • The solution has been tailored to detect: • Complex arbitrages impacting on Bilateral carrier agreements. • Negative margin (loss making) traffic • It has allowed the Revenue Assurance department to realise significant multi million dollar savings through identifying rapidly high risk call tariff arbitrages, which are a regular feature in International trading environments.

3. Case Study - II Intelligence around International Number Range Management • International Numbering intelligence has now been successfully utilised by two fixed operators to improve operating profits through identifying • Under charged customer calls to International Mobile Destinations • Opportunities for tariff arbitrage in the carrier trading environment • Over-charging of customer calls to International destinations • Routes on switches that need to be opened up

4. Case Study - III RA International Carrier Monitoring Solution for European Telco • A European National Telco had a requirement for revenue assurance capabilities within a specialist International Carrier Trading Division. In collaboration with the Holding Company RA teams, We designed and jointly implemented solutions, which enabled advanced analytics in the following areas: • Daily Traffic profiles, by operator and destination: - Used to indicate pattern changes, highlighting potential tariff arbitrage. • Daily Call Margins - Used to identify opportunities to reduce costs of international call routing, and loss making calls. • Reconciliation’s from actual CDRs to Interconnect Rating. • The analysis of carrier business tariffs for potential arbitrage opportunities also revealed numerous mobile termination destinations incorrectly classified as fixed, leaving the Operator highly exposed. This analysis is now being built into ongoing operational processes. • In addition, we provided expertise in the implementation of a revenue assurance test call solution to measure both quality of calls and also the accuracy of call event recording.

5. Case Study - IV Solutions for RA Least Cost Routing Analysis within a European fixed Operator • Through taking extracts of Interconnect rated data, We have worked with one major operator to correlate retail and wholesale call records to enable analysis of margins at the call event level • As well as margin analysis, this allows the team in Revenue Assurance to analyse the costs of call records to destinations and monitor least cost routing. • Anomalies are identified and discussed with traffic management, and potential financial savings are calculated using outputs from the solution. This has resulted in significant financial savings to date.

6. Case Study - V Rating Assurance Solution in UK Tier 1 Quad Play Operator • Within this quad play operator, an audit of telephony rating tariffs identified numerous instances of under charging on call tariffs. • Subsequent to this, and utilising extracts of rated call records, we were able to integrate Pro Optimis std code and tariff reference data into their data warehouses and build tools to detect inaccurate rating, whilst also producing monthly rating assurance KPIs. • Findings have included: • Under charging of customer calls to International Destinations • Under charging of customer calls to Operators • Under charging of customer calls to Premium Rate Destinations • Over charging of customer calls to Mobile destinations • The monthly KPIs have been successful in assuring management that all issues are being identified. • This solution has also been enhanced to enable re-rating of the Operator’s actual call traffic, which provides valuable revenue intelligence to the consumer and enterprise marketing teams and has enable them to generate multi million dollar revenue growth opportunities. • Examples include: • Price optimisation through comparison against competitor rates and tariffs • Additional revenue from the rounding up of call durations and charges

7. Case Study - VI End-to-End Revenue assurance system for Indian GSM operator • Indian operators existing revenue assurance system was slow, inflexible configuration and hard to access the vast amount of traffic. The existing system was not capable to verify the inbound interconnect invoices raised by the other operators and to determine whether or not a discrepancy exists. Indian operator was therefore looking for a much faster and reliable RA solution, which could be implemented very quickly. They had a number of specific requirements from a billing system as well as speeding up the call detail record (CDR) processing and mediation. It had to be able to map a variety of POI and trunk groups. In addition it had to support additional reporting for the fast growing carrier-to-carrier business. • Project Highlights • Processing 1.5 billion of CDR’s and quicker mediation • End-to-End automation of process, systems and operations • Minimum of 16 interconnect partner settlements, audit and integrity. • Higher invoice complexity and volumes combined with variety of formats • Mapping 304 POI’s and 210 Trunks. • Total time from Initial contact to Final delivery: 6-8 Months • ROI: > 300% • Profit margins increased by: 12%
