D-Link DPH-50U Skype USB Phone AdapterThis product has given nothing but trouble. The main problem is that it crashes in the middle of most calls that last longer than a few minutes. After downloading new software from the d-link web site the problem still persisted. When I contacted d-link I was told that the software hadn't been updated to work with Windows XP SP3 and that I would have to remove it and reinstall SP2. Furthermore, nothing on the d-link web site warned the potential buyer of this problem. Advice - don't touch it with a ten foot pole.
