Just to keep the reports going - got the same 2 rings and then hang up. A friend had it happen a few days ago, but I assume she wasn't hacked since this number still popped up as the originator not hers.
Number guru has about 10 posts on this number all saying the same thing....two rings and a hangup. One post says they "called back and recording said to call during regular business hours but never said what business they were." Hope this helps.
