Sorry for the newbie question. But I was always confused about the purpose of MTP. Why we would need MTP and how it is different from transcoder?
The concept of transcoder is pretty straight forward - when there's a codec mismatch (like g.711 / g.729), a transcoder will be used to "translate". But why MTP?
From some posts, traces, I've seen that MTP was involved when there's a codec mismatch. That confused me as well.
Thanks!
