keep getting calls from this number. when i answer it the is a brief silence, a beep and then some automated voice says goodbye! Weird

Last night I received a call from 2031513267 at 1:30am. After a 10 second pause they said goodbye and hang up. Occasionally I've had similar calls at daytime in the last 6 months, not sure if from the same number.

interesting that i found this number here, this morning I got a call from this number, somebody on the other side telling me somebody else try to log into my computer, ask me to check right away

We were woken up by this caller past midnight Pacific time. No one was there! Disgusted!

I got a call past midnight 12/ 18/14
