I have a phone, it's either "nortel networks 390" or a "vista 390", not sure what it is ( both names are on the phone, and I tried to google image it, but both names give me the right picture of my phone ).
Anyway, the problem is, the light is on ( as if I was already on a phone call ) at all time, and I can't receive any call, or make one.
I can compose a number, but it doesn't ring.
Everything looks plugged fine ( unplugged and re-plugged everything to make sure ) and I don't have any other phone in the house.
if you try to call your phone line with your Cell phone, do you have a busy signal ? If yes, try unpluging your phone from the phone jack, and try again. If you don't have a busy signal again, then your phone might be deffective. If it's still busy, then there might me a problem with your wiring in your home, or outside your home.
If you have a D-Mark installed from bell, you can try your phone directly in the D-mark.
If you have another phone, I would try another phone to.
