Call-recording hardware
Call recording hardware, or a telephone recorder, is hardware that can be used to record telephone conversations. Call recording hardware is most often used by law enforcement, lawyers, journalist, and call centers to record phone transaction with customers.
History
Law enforcement professionals began using hardware to record telephone calls in the 1890s. This required physical access to the lines over which calls were carried.
PBX based call-recording hardware is sold by PBX vendors and third parties. This hardware is attached to the PBX. It can be configured to record all calls or some calls, either randomly or on demand. Businesses, particularly call centers, use call recording for training, quality management, and legal compliance.
Consumer call-recording hardware was introduced in the 1970s, along with the first consumer-grade answering machines. These devices were connected to the same physical line as one of the telephones involved in the conversation. While the more sophisticated devices were automatically activated when a call was made, most were manual.
