The caller, Out of area ( displayed as ID on our phone ) ,  called us @ 15:55,03.14.2015. I was in backyard. It used 2-347-506-6983 to call.. When I returned the call 1 1/2 hours letter. It rung for a while, then recorded message" Thanks for calling 347-506-6983, please leave a message." then" sorry, the mail box is full.". I never know the caller. & this number.  I received   many unwanted  calls from New York, including area code (202 ) & other.
Caller::  Out of area..

WHY in the world would you return a call to an unknown number that doesn't leave a message??? People that do this will only receive more scamming calls. 'Curiosity killed the cat'.
