Video on a How to Use a Burner Cell Phone for TDoS

Here is a video from last years DefCon on how to use a burner cell phone to generate a bunch of calls for a Telephony Denial of Service (TDoS) attack. This allows an attacker to create a virtually untraceable and highly anonymous attack. Even with a single phone, you can generate enough calls for a long enough period, to affect a small target, such as a hospital ER/ICU, small business, a small PSAP, etc.
