The cause could be affecting your whole neighborhood or it might only be inside your home. You might be able to fix the problem without waiting for a visit from CenturyLink.
Plug a traditional corded telephone into the "test jack" on the box where the outside and inside phone wiring connect (also known as the Network Interface Device, or NID). Depending on your home, your NID (and the test jack) may be inside or outside of your home.

The problem could be inside your home, either with your phones or your wiring. Here's how to isolate the potential problem.
First, make sure all phones are hung up correctly. If you find any phones off the hook, hang them up, give it a moment and then see if this corrects the problem.
Next, anything that is plugged into a phone jack should be unplugged from the phone jack and the electrical outlet. Then using a corded phone that you know works properly, plug it into each jack, one after the other. Check for a clear dial tone.
Static, hissing, echoes and other noises you hear on your landline are often caused by simple things you can check and correct on your own.

Your phones battery may not be fully charged or the batteries may be flat (not holding a recharge), try replacing the battery.
Check phone cords for damage or cracks and replace if necessary.
Avoid using line splitters - adapters that allow two phones to fit on one phone jack. They can cause phone line noise. Plug your phone directly into the phone jack - does that solve the problem?
