Who called from 7323449172

Some Fu@$er called from this number ... pos.

An ignorant pos. I hate these idiots calling. Nothing to say, no message. I will never call back!!

called.  no message.  no reason not to block.

As above.  The usual cast of idiots.

I experienced the same thing.  But Xfinity Phone blocking refuses the number entry as "invalid number".
So they can call out but you cannot call back....I wonder why?
