What causes an echo during an InfoGate conversation?
Echo heard in an InfoGate network conversation can be caused by many irregularities. The major sources of the irregularities could be the local telephone switched network or PSTN, cabling or other equipment installed between the PSTN and the InfoGate Gateway, and the InfoGate\Internet network. InnoMedia has gone to great lengths to eliminate echo from its product. In the laboratory, where irregularities can be eliminated or controlled there is no echo at any time. However in the real world, which concerns InfoGate users and customers, the InfoGate Gateway has two controls in the Universal PRM application that can be used to suppress echo. These controls are labeled Gain and Echo Cancellation.
