If you're designing a structure, one way is to build the room underground, or with thick concrete walls. If the room already exists, you should be able to buy a device to block the signal.

Get a Faradays cage. Or find a room with steel reinforcement (this is a Faraday cage) The 'squares' in the reinforcement must be smaller than the wavelength of the signal from the phone though.
