Conference phones, work on the other in full duplex mode. Thus, all parties may at any time and speak no ill effects. He does this by using a digital signal processor, which prevents information by loudspeaker that the noise for microphones to be recorded eliminated. This is known as echo cancellation. In fact, recognizes the digital signal processor of the loudspeaker and eliminates the noise of what the microphones.
