In some communication applications, a near-end talker employs a cellular phone that either operates in a noisy environment and does not support artificial noise injection or injects noise but supports a simple, fixed noise injection. This may result in "blanking" of the background noise and result in repeated "are you still there?" questions or premature termination of a call. In order to prevent this feeling of "blanking," a suppressor backfill module according to an example embodiment of the invention backfills those blank periods with noise, optionally in an inverse relationship with power of noise in a near-end signal, resulting in repairing sound quality degradation and giving a far end talker a feeling of call continuity. As a result, the near-end and far-end talker have a better experience during the call.
