Such "ring-back" or "one-ring" scams have long plagued the telecom world, but in recent weeks, the problem has come back strong nationwide.
As for what cell phone companies are doing to stop such home and cell phone "cramming," there's not much they can do, they say, besides tell customers to closely read their bill.

Sprint officials note their customers can block up to 40 phone numbers through their corporate website, setting the account to block any third-party charges.
Such scams do break federal telecom rules, but they're not a small problem.
