Can I plug the standard phone into an ethernet jack

cat5ethernetphonerj-45

I just moved into a new house and it's wired for ethernet. There's a junction box that has a "Bridged Telecom Module TM-8" in it. My cable modem's phone jack is plugged into the "Line In" on that box and their are 8 slots all running to various ports in the house. All the jacks in the house are RJ45. Is there a way to plug my old phones into these jacks or do I need to upgrade to phones that use this connection?

  • You can plug standard "square" RJ14 cables into a RJ45 jack, as long as the port is wired to your phone line. It should click in. You need to figure out which ports are wired where.
