I just got the S685IP from Hip-IP last week, they arrived day after
the order. The bluetooth is a great extra, I can walk around the
office with my bluetooth headset in. I am not sure about the HDSP as
yet, do not think i have used the phone enought to notice a
difference. Generally though it seems to be a good piece of kit, i am
going to get some additional handsets now.
