If you answer they seem to hang up. I then answered and didn't say anything. There was a conversation going on between two persons with Indian accents with other voices in the background. I stayed quiet for about 30 seconds and the line stayed open. I then cupped my hands around the mouthpiece and screamed loudly. Hopefully they were wearing headphones. I'm in New Zealand. I rang the number back and got an answering message for AlwaysOnVacation.co.nz.
