One of their dealerships, Kendall Dodge Chrysler Jeep Ram, in Kendall, Florida, was besieged by persistent, recurring Telephony Denial of Service (TDoS) attacks. Huge floods of telephone calls would overwhelm their telephone system. During these attacks, staff had difficulty calling out, and customers and prospects struggled to call in. It was crippling their business.
ACA reached out to their PRI (Primary Rate Interface) line provider and upstream voice service provider. These providers had nothing in place to prevent these attacks. ACA management got their lawyers involved and sent letters to these providers. A lot of time was spent, but without effect, and the TDoS attacks continued.
ACA dealerships strive to give their customers great value and attentive service. The disruptions caused by these incessant TDoS attacks were making it very difficult for ACA staff to continue providing this level of service.
Carlos Hernandez, IT Director for ACA, described it as a helpless feeling.
