About IP CTS

Internet Protocol Captioned Telephone Service (IP CTS) is a form of telecommunications relay service (TRS) that permits an individual who can speak, but who has difficulty hearing, to use a phone to simultaneously listen to the other party and read captions of what the other party is saying.


IP CTS allows persons with hearing loss to take advantage of advancements in communication technologies and Internet connections at their residences and work places to more effectively use the telephone in their job and daily lives.


For nearly 500,000 Americans with hearing loss, IP CTS is vital to enabling effective, reliable phone conversations.
