"Of course the carriers could instead use some extra BW and transmit the actual background noise of whoever you are talking to."
Another effect is the overall system would get more complicated and latency would increase because you'd need some fancier echo cancellers.
- pjc50 12y agoIt's less complicated and unrelated to echo cancellation; you just tell the transmitting codec to always encode whatever audio you've given it, rather than detecting silence. (Echo cancel is usually in the local audio path before data is passed to the codec. So the outbound codec would hear silence rather than an echo of inbound audio. At least that's my experience of working with PJ-SIP)
