Abstract
A system for preventing noise transmission at the end of a telephone call includes a telephone having a handset and a base unit. The telephone has a proximity sensor configured to detect when the handset is in close proximity to the base unit prior to the handset contacting the base unit. A control element communicates with the proximity sensor and prevents transmission of sound received from the handset when the proximity sensor indicates that the handset is in close proximity to the base unit thereby preventing transmission of noise caused by the handset contacting the base unit.
