Voice Activity Detector (VAD), Discontinuous Transmission (DTX) and Comfort Noise Generation (CNG)
Global IP Solutions' Voice Activity Detector, Discontinuous Transmission and Comfort Noise Generator software is used to reduce the average data rate during silent periods of speech. GIPS VAD reliably detects the presence or absence of speech, DTX codes and transmits data for non-speech frames and CNG generates a sound that matches the actual background noise.
