Internet Protocol Relay Service is a text-based form of TRS that uses the Internet, rather than traditional telephone lines, for the leg of the call between the person with a hearing or speech disability and the CA. Otherwise, the call is generally handled just like a TTY-based TRS call. The user may use a computer or other web-enabled device to communicate with the CA. IP Relay is not required by the FCC, but is offered by several TRS providers. For more information visit the IP Relay Service consumer guide.
