Modernizing SIP routing: protecting softswitches from fraud
Protecting operator voice traffic from fraud and spoofing by transitioning to component-based architecture and implementing cryptographic call validation.
MNP routing in modern networks: from legacy signaling to API-first architecture
Network evolution toward 5G and cloud architectures requires rethinking MNP routing. Discover how to transition from monolithic systems to modular, API-first solutions for efficient number portability.
Protecting telecom networks from signaling fraud: SS7, Diameter, and SIP security architecture
An analysis of signaling protocol vulnerabilities and methods for building architectural defenses against fraud in telecommunications networks.
Signaling security and anti-fraud in operator networks
An overview of securing SS7 and Diameter signaling protocols. How telecom operators can counter IRSF and Wangiri fraud schemes to ensure network integrity.
Caller ID authentication: implementing STIR/SHAKEN and securing voice cores
An analysis of the STIR/SHAKEN architecture for preventing spoofing. We examine the steps for modernizing SIP networks and implementing cryptographic call verification.
Autonomous networks by 2027: telecom architectural shift to AI, ODA, and 5G Core
Transitioning from monolithic BSS/OSS to modular ODA and 5G service-oriented architectures is a prerequisite for enabling AI and launching autonomous networks.
Modernizing legacy telecom systems: a phased cloud-native transition
A practical guide to telecom modernization: breaking down BSS/OSS monoliths, securing legacy signaling protocols, and transitioning to ODA and 5G SBA architectures.
Contact centers and customer service in telecom
Telecom contact center architecture requires updates to address fraud risks. We explore integrating AI agents, omnichannel strategies, and VoIP security.
Signaling security in telecom: from hybrid threats to 5G architecture
The transition to 5G does not eliminate signaling security threats. Coexistence with legacy protocols like SS7 and Diameter requires end-to-end monitoring and integrated signaling firewalls.
Anti-fraud in telecom: integrating billing and softswitch
How to build low-latency integration of the signaling core, billing, and anti-fraud systems to block IRSF and other fraud in real time.
MNP and routing: architectural challenges of 5G
Transitioning from monolithic BSS/OSS to API-first architectures is critical for MNP routing speed, signaling interface protection, and fraud prevention in 5G networks.
Telecom billing: rating, mediation, and BSS integration
How to integrate legacy billing systems with 5G cloud cores, minimize fraud losses, and transition to modular architecture based on TM Forum ODA standards.
