Received a call from this number at 7pm Tuesday 19th Jan 2010 asking to speak to my wife (a doctor) by name. When I questioned them they hung up. Our number is ex-directory and we virtually never receive cold calls. I rang back (141 of course) and by some fluke/crossed wire got through. The girl who answered seemed confused and asked someone with her how I had got thriugh before hanging up. I could not get through again. BTW this is to a landline number. I have discovered the company who owns the number is Gamma Telecom Holdings Ltd
