Simultaneous ring is missing from my options. I am in North Glendale, Az. When will it be available?

Don't get your hopes up.  It seems like NOMOROBO's heyday has passed.  I enrolled and while it has successfully blocked a couple calls, dozens of others- mostly using spoofed numbers, have been ringing my phone.  Also, it seems the criminals have figured out a strategy to get around simultaneous ring by placing two nearly simultaneous calls to your number- the first one occupies the number that handles the robocalls which enables the second to ring your phone.
