Bum dialled I think - Woman rang and could hear her having a conversation with two other women. No idea who they were as I kept saying hello, but they couldn't hear me and kept talking about volvo's, trips to Japan, Greece, Italy parties etc. There was a child as well. Weird but I'm guessing is was some call centre ringing about a survey or to raise funds for a charity and they didn't realise I could hear them.
