Who called from 2567123040

I call the number back and it IMMEDIATELY makes my cell RING.....I think WTH and answer it, it's a telemarketer.  I tell her she has the wrong number....call the number back and NOW it won't work.  It drops the call over and over and I dial it Manually (I had been hitting the recent call button to "return" the call).....it rings and rings...changes to a STRANGE ring that sounds like it's in a tin can and then drops the call.  
SO STRANGE!

The number called me as well. I tried calling it back and it just drops my call.

they called and woke me up but hung up when i said hello and when i called the number back it kept disconnecting

calling at all hours.  no responce when answered

It calls me as well, it shows up as a Florence, AL number. I call it back and it says it is either a non working number or drops my call.
