Hi. As i know analog phone lines generally should have frequency response from 300 to 3300Hz. Of course lower frequencie can be reproduced too, but headsets usually can't reproduce lower sounds. Cellphones using GSM codec 8kHz and less than 14kbps rate but some
Re: Telephone Sound Quality
Really? I didn't know that. When I call people on my iPhone 5S, it sounds like 8 KHZ audio. What about Wi-fi calling and VO LTE? Does that enhance voice quality? Does it only work if both people come from the same service and have the wi-fi calling or VO LTE

I guess posting an audio in 8khz is lots, lots smaller and faster than let's say, 44.1khz., thus delivering instant communication. And instant communication is very important.
