service works through a Communications Assistant
who reads messages typed into a TDD/TTY device
by a speech or hearing impaired individual to you.
The Communications Assistant then types your
spoken messages to the hearing or speech impaired
individual. Telecommunications Relay Service is
available 24 hours a day, seven days a week, and
every call is strictly confidential.
