Case Study: Orange Egypt achieves reliable invoicing and real-time CDR analytics for 200 million calls per day with Talend

Making sure invoicing for telecom services is reliable

Orange Egypt, the Group’s largest operation with about 33.4 million customers, needed to analyze vast volumes of Call Detail Records (CDRs) — roughly 200 million calls per day — to ensure reliable invoicing, detect fraud, and provide near‑real‑time reports for marketing, accounting and other teams. The operator required an open, scalable data integration platform that could feed multiple systems (marketing, pricing simulation and revenue assurance) and accommodate future integrations.

Orange Egypt deployed Talend Big Data with implementation and industry expertise from GlobServ, building an Oracle‑based ODS and integrating cleaned CDRs into Siebel CRM; GlobServ also adapted an ASN.1 library to handle Ericsson data formats. Delivered in three months, the solution processes 200 million calls daily, improves marketing responsiveness and pricing simulations, strengthens revenue assurance to detect data loss, and reduced implementation and integration costs.
