GETUS offers ATA devices that can be configured to enable TTY services. Please advise GETUS if you require this when you place your order so that GETUS can pre-configure your device before shipping it to you. If you require this configuration after you have received the device, please reach out to our Support team and we would be glad to set this up with you remotely. GETUS does not support customer-brought ATAs, but we may be able to help you figure out how to configure your ATA for TTY. Please contact Support at 1-800-396-1023.
