Well this is a rather mixed review. The customer service is very good, the physical handsets are not bad but limited to just one choice of desk phone and one type of cordless. One very major and serious problem for this technology, if your in a burning building and go to dial 999 you shockingly won't get connected. The VPS technology has a work around but this doesn't seem like the urgent priority that it should be, perhaps until someone finds themselves in this situation. I am surprised its even legal tbh and screams legal challenge in the near future, god forbid something happens. Another problem is the phone app is far from ideal, the technology on screen is very limited and the design of the screen is not very sharp, also I don't like the fact that you can click "log out" so very easily, this should be hidden a bit more so that you can't accidentally lock a handset out of the network and not even realise you've done so. But on the plus side, the staff are very helpful, the technology is very clever and the pricing not too bad.
