Need service to block area codes

[N8_V]

I realize there is some canned response about not being able to block area codes or large groups of numbers, but I am tired of hearing the excuses.  We pay way too much not have this feature available.  I am willing to pay more as needed, but I demand a feature to control calls to my device.  This should allow me to block entire area codes and extensions or simply "white list" the numbers that want to allow.  There is absolutely no good reason why this is not available for consumers.  This feature service needs to be added.
