Can both parties speak/listen at the same time? In some systems, the other side is cut off while you are talking and you cannot hear when the other side is talking. Is this what is meant by full duplex? If not, does anyone know if the next model up, the 710, can do this?
Both sides can speak and hear at the same time. We had one problem with an echo, but this was obviously due to the other side, because on all other occasions our Jabra worked perfectly.
