I bought this phone as a gift for our cousins in South Africa. First of all the power supply was not the dual voltage so I had hunt around to find an appropriate power supply to work for 220V supply. It did work for a while and we were able to make some Skype to Skype and Skype Out calls from South Africa. However, the next problem started and it is that the phone hangs up and keeps on displaying "Retrieving Contacts" for ever and ever. There is not much one can do other than powering this up and down, unplugging and replugging, but there is no way that this phone can be reliably booted up. I was able to get it back to work but I had no idea what made it work. Now it is on the blink again. There is not much I can do right now since the phone is in South Africa. I think Amazon should be getting back to Philips to resolve these problems or should stop selling Philips products on their website.Philips VOIP841 PC-Free DECT 6.0 Wireless IP Phone
