Where does it terminate? If it's a patch panel with nothing plugged into it, it's a data line. Consumer phones would use RJ-11. A VOIP phone would still need to be patched to some internet connection. Which would be the same patch panel used for the rest of the house's internet service.

It terminates in the laundry room with a motherboard, what I think is a patch board, and a bunch of coax lines labelled CMP.

A couple of pictures would help so we know what you're dealing with.
