Description: This object indicates whether the silence gaps should be filled with background noise. It is applicable to FXO, FXS, E&M subscriber lines and E1/T1 voice subscriber line.
What is hh3cVoiceIfCfgCngOn?
Controls whether Comfort Noise Generation fills silence gaps on this voice interface with background noise instead of dead silence, applicable to FXO, FXS, E&M, and E1/T1 voice subscriber lines. Admins keep this enabled so callers don't perceive a dead line during quiet moments, since abrupt silence can make callers think the call dropped even though it's still connected. Setting hh3cVoiceIfCfgCngOn to disable(2) on a voice port would make silent pauses in a call sound like complete silence rather than the usual faint comfort noise.
