Call Types Overview
Telecommunications Relay Service (TRS) is a telephone service that allows persons with hearing or speech disabilities to place and receive telephone calls. TRS is available in all 50 states, the District of Columbia, Puerto Rico, and the U.S. territories for local and/or long distance calls.
TRS uses operators, called communication assistants (CAs), to facilitate telephone calls between people with hearing loss and/or speech disabilities and other individuals. A TRS call may be initiated by either a person with a hearing or speech disability, or a person without such a disability, with the CA serving as the link for the call.
