Zycoo has released a minor firmware update for the ZX 20 and ZX 50 Series IPPBX systems. The firmware adds new features to prevent some types of Denial of Service attacks, and although this doesn’t negate the need to protect your PBX with a decent firewall, it does offer a better experience for unprotected systems.
