I remember that podcast episode, but that case was specifically about fraud and someone getting dialers to call people and play weird stuff to keep them on the line as long a possible. It's only a few cents here and there but it adds up if you automate the process.
IIRC, the situation was brought up at a telecom conference and the calls dropped suddenly; suggesting at least one of the people involved was deep into the industry and probably at the conference. They even get an FBI agent on at one time who is convinced they'll find this person.
