IP phones with ambient noise generation

 prices on 159 models  

Comfort noise generation

— a system that creates a quiet noise on the line with a tone that is comfortable for a person. Its necessity is due to the fact that during pauses, especially in devices with voice activity detection (see the relevant paragraph), an unpleasant “deep silence” can occur in the speakers, creating the impression of a disconnection. Comfortable noise avoids this silence
