The installation of the SC's VOIP telephone system in our London flat was a unmitigated disaster. It is still not working properly but I was too ill to keep demanding that the problems be resolved. Clearly, having a 6th phone for a system designed for a maximum of 5 phones was a major error. This 6th phone should be taken back. Also, there is no longer any phone reception in the Guest room. We shall be back in the UK in October and we shall expect the system to be finally sorted out. MD-H PS - I was a great fan of SC for some 20 years and recomended SC to many friends, now I am no longer one.
