ABSTRACT:
A method of generating comfort noise in a communications includes selecting a packet of data from a stream of packets being received across a communications network, the packet comprising a selected number of data samples. Ones of the data samples from the selected packet are played out in a sequence as comfort noise to fill a dead gap. The sequence is reversed when a randomly selected sample in the packet is reached and corresponding ones of the data samples are transmitted across the network as comfort noise after the order is reversed.
