At any rate, the jack on the end was RJ45, so it wouldn't have been
easy for someone to plug it into a phone jack, but I'm sure a
determined idiot could manage :)
I've seen damaged network cards and network gear where someone plugged a
RJ11-RJ11 cord from an analog phone system into the RJ45. I've also seen
damage caused the same way by commercial phone systems, which used RJ45
connectors.
