One of my customers has build a new house with pre-installed cables for internet. The only thing he didn't think about was installing a cable for his telephone line.
Behind his desk, he has a "spare" UTP cable, my question.
Can this cable be used to replace a telephone line.
This client has a internet and telephony contract, using a experiabox phone/internet modem.
Any help would be great. I knowe I have to use a RJ11 plug.
