I received a message from my neighbor that someone from this number was trying to reach me.  My neighbor!!  I don't believe that any legitimate organization calls your neighbor to track you down.

Got a call from this number looking for my brother.

Didn't interrupt the call I was in to answer a number I didn't recognize from an area code where I don't know anyone. If it's important they can call back and leave a message because I still won't answer an unrecognized number.

Left no message
