Creation of keypad based "Do Not Call" list, regardless of being a "landline" or "mobile" line.
After answering a call and deciding it is a "nuisance" such as spam or marketing and INCLUDING Political, before hanging up you can press a key combination such as #DNC ( #362 ) and the caller's details are automatically added to my enforceable DNC list. If the same details appear a number of times on my list, as well as on the lists of others, there would be reason to pursue for violation.
I am tired of constantly making sure my numbers are on DNC lists, yet also constantly receiving nuisance calls ( and I consider political calls as nuisance calls), many of which are recordings that I cannot tell them to remove my numbers.
