Hey all,
I have been searching for something about this for a LONG time.
My wife and I BOTH have Lumia 1520's and are both on WP8.1.
We both have call+SMS filter ON and in the Advanced Settings we have Block Withheld Numbers turned On.
Despite this, we keep getting calls from an UNKNOWN caller almost every day. The caller calls my phone, hangs up and then calls my wife's phone. Anytime we pick up the call, we get hung up on. So blocking this would help a LOT!

As you can see, the calls are grey'd out and cannot be manipulated.
Some days, they are pretty persistent:

I have called AT&T, but their only suggestion is to change my number. For me, it's not a big deal, but for my wife, it would be and something that would take a lot of convincing to accomplish.
If anyone has any suggestions, please let me know!
Thanks all!
