    Problem with Telephone
    Hi Phyllis,
    If the phone has recently been wired, then it is possible that the two main wires need to be reversed. The wiring of the phone jack should be verified for proper connections.
    If the phone has been working all along and the wiring has not been altered or changed then you should contact your phone company and explain the problem with the phone service.
    I hope this helps,
    Dave

    Dial Tone but Phone Does Not Work
    My landline phone has buzz and a dial tone but does not work. It also tells me on the display when the line is in use, and when it is not. I have a cordless phone, as well as a non cordless. Could you give me any suggestions.
    Thank you.

    Hi Joan,
    Locating a 4Wire Telephone Cord
    Have you tried looking for the black 4 wire phone cord at your local Radio Shack store or try searching on the internet? If your phone is an older model then maybe a thrift store may have some cables like the one you are referring to.
    I hope this helps,
    Dave

  5. Tom says:

    Hello, I am installing a new phone jack that contains the red, green, yellow, and black wires. The wires coming from the household box are solid blue and solid white. Which combination do I use in connecting the White and Blue wires too?

    What a great site – thanks! I’m replacing a phone jack and the wiring didn’t match up in my old house. Now we can get the phones back up … I hope!
