That is a Gigaset was soon clear, but the question was, which can do what I want, so I am informed beforehand on the well-made Gigaset website and found it. Did the Gigaset C610A purchased together with the C610H handset incl. Charging cradle, because me especially interested in the baby monitor function. All basic functions such as voice quality, phonebook transfer, haptics, etc. are wonderful. But the baby monitor function is a real truffle. Power of Small rampage, selects the parked in the nursery handset my phone on (or alternatively an internal handset) and I can go and ran to hear what's going on. Only time coughing vigorously, dreaming out loud or really awake. If everything is ok, just hang up and the C610 goes back into the baby monitor function. Now I can move quite relaxed and out of reach of all standard baby monitor and am always in the picture, if what is going on in the nursery. A really well thought out and implemented feature!
