The MajicJack mini has both an RJ-11 and an RJ-45 port on it. RJ-11 for the telco wire to the phone system base unit’s Line In and the RJ-45 goes from the MJ into a LAN port on the house modem.

Thanks. But I gather MJ also works just by being connected to a PC that is connected to the Internet via wireless.

Don’t know how it would work if the PC is powered off. No power to the PC’s RJ-45 or USB ports. You can probably find out more at MJ’s website.
