It is wise to ask the person how they would like to be reached over the phone.
If the answer is Oklahoma Relay, then dial 711 (800-522-8506 for English or 800-662-4955 for Spanish) to reach a communications assistant. Provide the area code and telephone number of the person you wish to call. The communications assistant will dial the number and connect you to them.
If needed, the communications assistant will explain the process before connecting the call.
