I got a call from this number, so I redialed it using my no-number skype subscription. The first time, there was noone on the line, and it sounded like someone was just listening on the other end of the line. I set up my 2nd account to call on another computer I have and did two simultaneous calls to this number both with no-number skype subscriptions. Both times you could hear callers in the background talking. The two voices that came on answering the call back were different males.
