Voice Activity Detection/Silence Suppression
Voice Activity Detection (VAD) detects whether or not speech is present. This lets the LTE
Device reduce the bandwidth that a call uses by not transmitting "silent packets" when you are
not speaking.
Comfort Noise Generation
When using VAD, the LTE Device generates comfort noise when the other party is not
speaking. The comfort noise lets you know that the line is still connected as total silence
could easily be mistaken for a lost connection.
Echo Cancellation
G.168 is an ITU-T standard for eliminating the echo caused by the sound of your voice
reverberating in the telephone receiver while you talk.
