Call had been blocked so my phone didn't ring.  All I know is that it is a cell phone calling from Forest City, NC.  I've also received several other calls from numbers very close to this one, so I suspect it is a call center with many different numbers to get around call blocking.  I'd been getting calls from multiple close numbers also from Forest City by cell phones for a month.  They haven't called for several days when they had been calling 2 to 3 times a day before that.  This could be the same group trying a new run of numbers.
