As you can see in the picture, all four phones charge up and all four bases seem to work as well. I don't have a landline so I cannot test the phones to see if they work. One of the bases has a external antenna and can record  messages. I know that this works because there is 52 messages on it. I'm not sure how to erase them
Two of the phones are missing the little back pieces that hold the battery in and the other two have those pieces
