Oklahoma, Texas and Iowa Relay Centers
(Special Services For The Hearing/Speech Impaired)
Relay Centers are a public service which guarantees all citizens access to prompt, professional and accurate communication through the telephone. Consumers of these specialized services, specifically people who are deaf, deaf-blind, hard of hearing or have difficulty speaking, can communicate on the telephone via TTY/TDD, Voice Carry Over (VCO), Hearing Carry Over (HCO), Speech-to-Speech (STS), Spanish-to-Spanish and Captioned Telephone in order to connect with family, friends or businesses with ease
Here’s how the relay center works:
Dial 7-1-1 or the appropriate toll-free number provided to connect (shown below). A qualified Communication Assistant (CA) will ask for the area code and number of the person you wish to call and will begin the relay call. Generally, the CA will voice the typed message from the text telephone (TDD/TTY) user to you. The CA relays your voice message by typing it back to the TDD/TTY user.
Specialized Services:
The relay centers offer specialized services for individuals who have difficulty speaking and for Spanish speaking residents. Specially trained CAs are on hand to assist in these types of calls by dialing the associated number provided. Since relay centers offer a variety of services, please refer to the website listed or call Customer Service for more detailed instructions on how a particular call is processed.
Access to Services:
Both 7-1-1 and the 800 numbers are toll-free calls and provide access to the same relay services. If you are experiencing trouble dialing 7-1-1 to reach relay center, please call Hilliary Communications Customer Service. All relay services are available 24 hours a day, 7 days a week. Consumers may place relay calls to English and Spanish speaking persons, across the United States and even internationally. By law, each conversation is handled with strict confidentiality. There is no charge to access relay center, although standard long distance charges apply.

Emergency Calls

Please note that 7-1-1 is only to be used to reach the Relay Center.
In an EMERGENCY you should continue to use 9-1-1.
For emergencies, call 9-1-1 or your local emergency service TTY number directly, without using relay. The Americans with Disabilities Act (ADA) requires that 911 centers have a TTY and be prepared to handle emergency calls placed in this manner. The Relay Center will make every effort to assist you in an emergency. However, it is important to understand that relay centers are not 911 centers and do not assume responsibility for emergency calls.
