I saw a new cordless phone made by Motorola in a retail outlet today that is supposedly "Secure from eavesdroppers." I asked the salespeople for more technical info, but they weren't very helpful. Does anyone have any information on this?

I have one of these, it's a good phone. I think the security will stop only an off-the shelf scanner. My understanding is that the signal is not encrypted, but only phase-inverted or otherwise shifted. Mike
