My phone is a Uniden SS E27+1 Visual and Hearing Impaired Digital Corded Phone & Cordless DECT6.0. For some reason it's gives message the line is busy and I'm unable to take it back to the dial tone.

DO you have a 2 line model? If so check and make sure the conf (conference) button is not pushed as it will keep the line off-hook forever. Hope this helps!

First be sure you have dial tone at the jack. Use a corded phone to do this with. If you do have dial tone then be sure you have ac at the outlet that the transformer is plugged in to. If there is no dial tone at the jack...go to your interface box outside and check for dial tone there....if none call the phone company. If you do have dial tone then you need to check your wires to the jack...or have the phone company do it for you. If you don't have ac at the outlet....check your breaker box or have an electrician check for you.

We've had the same problem with our new Uniden phone. Sounds like someone's on the other line - no dial tone and answering machine doesn't work. The telephone line works though because we plugged our old phone in and it works fine. Any solutions anyone?
