Overview
- Regulator AgCom confirmed that carriers will activate a second filter on 19 November targeting international calls that fake Italian mobile numbers.
- The first phase, active since 19 August on spoofed fixed‑line CLIs, prevented roughly 40–43 million calls in the initial weeks, according to figures reported by the authority.
- Officials estimate about 50 million spoofed mobile calls per month and expect a sharp reduction once the mobile filter is switched on.
- Blocking fake mobile CLIs requires real‑time automated queries at international interconnection points to confirm number existence, current operator via the portability database, and the subscriber’s roaming status.
- The system is instantaneous and automatic for users, though operators are investing to meet the technical demands, and authorities warn some fraud will persist as scammers pivot or exploit calls that current tools cannot block.
