Abstract
An automatic handset lifter is used with a wireless communication system. The system attaches to a conventional telephone and creates a communication link between the telephone and a portable device such as a wireless headset. The system automatically detects the ringing of the telephone by sensing magnetic fields of the telephone speaker. Upon ring detection, the system creates a communications link with the remote device and deploys a mechanical lifting device to lift the handset. Lifting the handset activates the telephone cradle switch to answer the phone and thereby allows the remote device to communicate over the telephone.
