start_check
Start a spam label check
Start a check of what AT&T, Verizon and T-Mobile phones show when a number calls. Returns the test line to call ('dial') for each carrier and a check id (and a token for a keyless check: keep it). The number being checked must then call each test line within the window. The first check on a number is free; later ones need a key with funds.
