System and method for suppressing silence in voice traffic over an asynchronous communication medium
Abstract
A method and system for increasing the efficiency of providing bandwidth for voice traffic to a data provider via an asynchronous communication medium are provided. This is generally accomplished by not transmitting any data during the silence periods and playing out background noise (i.e., comfort noise) at the other end, to obtain significant bandwidth savings.
