This document summarizes APIBAN, a service that provides IP reputation data via API to help secure VoIP systems like Asterisk and FreePBX from abuse. It discusses how APIBAN works, including how it maintains an active list of banned IPs for 7 days using globally deployed honeypots. It also provides examples of how to integrate APIBAN using its API or open source clients to block IPs in IPTABLES. The document encourages attendees to try out APIBAN for free and ask any questions.
