Why Fraud Calls Are a Global Issue - Protecting and Modernizing Voice in Emerging Markets

Explore the global challenges and modernization patterns of voice networks in emerging markets through this 11-minute podcast episode featuring TelcoBridges CEO Maximilien Le Sieur and VP of Client Technical Services Luc Morissette. Discover how telecom operators worldwide are transitioning from legacy TDM systems to IP-based packet networks while managing massive mobile subscriber growth, with examples like Brazil's 250 million subscribers. Learn about the universal fiber, broadband, and IP trends affecting different regions at varying speeds, and understand the two major challenges facing operators: justifying budget allocations for legacy voice infrastructure and combating fraud in fragmented regulatory environments where unified rules are lacking. Examine practical solutions including extending copper and TDM assets with VoIP gateways, implementing SIP protocols near subscribers, and deploying scalable Session Border Controllers (SBCs) to protect both media and signaling on IP networks. Gain insights into IMS (IP Multimedia Subsystem) implementation, including how operators use ProSBC to interface with IMS cores and integrate mobile with fixed-line services while maintaining critical legacy services like emergency 911 access. Understand the modular approach to subscriber management across mobile and fixed networks, and see how these modernization patterns remain consistent across different countries and operators despite varying implementation timelines.

Syllabus

00:00 Introduction: modernization patterns, mobile subs, IMS, upcoming events
00:54 What we’re seeing globally same tech, different stages by country/operator
01:25 Packet networks: data and voice both as IP packets; mobile scale Brazil: 250M subs
02:24 Fiber/broadband/IP trend is universal—timing differs by region
02:52 Challenge #1: Budgets and justifying legacy voice spend
03:20 Integration reality: fit with what exists; keep costs and effort reasonable
04:10 Customization cost people/time vs. choosing easier-to-integrate solutions
04:27 Challenge #2: Fraud in fragmented regulatory environments global, not local
05:26 Why unified rules matter; interoperability of “non-fraud” signals end-to-end
06:14 Immediate needs: extend copper/TDM with VoIP gateways; flip to SIP near subscriber
06:52 On IP side: scalable voice with SBCs; media vs. signaling differences; protect both sides
07:52 Same patterns across countries/operators—continuous evolution
08:04 IMS in practice: customers using ProSBC to interface IMS cores
08:25 What IMS is: specs-driven core enabling interconnect across old/new networks
09:50 Modular components; integrating mobile with fixed line
10:05 Subscriber management: mobile vs. fixed; keep legacy services e.g., 911 reachable
11:04 Wrap-up & upcoming events
