This purchase was to extend an existing Graphite system. I had tried some 'new' dect alternatives which just wouldn't speak to my existing Graphite answering machine reliably, and BT helpline was a complete waste of time. So this was a low cost option to add another phone. It works perfectly and I get all the features of the original system. It looked as if the Graphite range is no longer available new, and this proved a great way to expand. And on the plus side, I've got a spare answering machine hub in the loft now!
