The Pennsylvania Relay Service is an AT&T phone service regulated by the Public Utility Commission offering persons who are hearing, deaf, hard of hearing or speech disabled three ways to connect using the telephone: Traditional Relay, Video Relay, and Internet Relay. Users simply dial 7-1-1 to connect to a skillfully trained Communications Assistant, or CA, who follows a strict code of ethics and confidentiality. The CA then relays your messages to the other person. PA Relay is available 24-hours a day, seven days a week and virtually eliminates the difficulty in communicating by telephone.
