What is wrong with my land line?

Question

i can use the internet, but there is no dial tone on the home phone, and when i call this number, i get a busy signal.

there is no network interface device, i found something similar, the wires are all secured tightly.

so i wonder if i unscrew those wires, and s***w them back on again, will that solve the problem at all?

Answer 1

I went out to the NIU panel at the side of the house.  You can plug a phone cord into it.  If you get a dial tone, the problem is inside your house.  If no tone, the repair is free because it's the company's fault. There are only 2 places to plug in a phone so you will find it./
