ABSTRACT:
During communication over the network, periods of silence may exist. During these periods, the system may enable a user at a user terminal to define characteristics of a comfort signal. The system may monitor transmission to detect periods of silence. The system may adapt the monitored transmission by adding the defined comfort signal during the periods of silence, as background noise, or during periods of silence and as background noise.
