Who called from 7184509493

Got a call from this number.  They didn't leave a message.  I called the number back and got a recording saying that this number is not in service.  How can you receive a call from a number that is not in service?  Sounds fishy.

some automated evangelist message

sounded like a preacher of some sort. I didn't listen long enough to find out the purpose of the call

I got a one ring phone call. I never called back, I just blocked the number. If it is no longer registered then it is waiting to be assigned to another marketer.
