FEDERAL LAW PROHIBITS ANYONE BUT REGISTERED USERS WITH HEARING LOSS FROM USING INTERNET PROTOCOL (IP) CAPTIONED TELEPHONES WITH THE CAPTIONS TURNED ON.

There is a cost for each minute of captions generated, paid from a federally administered fund. No costs are passed along to individuals who qualify for the service.
