I have a twin BT Stratus Digital Cordless Answerphone with two handsets and second charging base. It seems that the base station is faulty because neither handsets get any dial tone. They still communicate with the base station and can operate the various answerphone settings, etc. Offered for spares as I suspect the handsets are still fine, just a faulty base station. The handsets could benefit from new batteries but they are cheap enough in Poundland.
