times and holding SLA commitments to wholesale partners
•Run traffic-anomaly and fraud monitoring (FAS, CLI manipulation, spikes to high-risk
destinations); drive blocking decisions and technical escalations to vendors
•Investigate quality degradations using SIP traces, CDR analysis and monitoring
dashboards; adjust routing and escalate to carriers with evidence-based reports
