Real-Time Text RTT

Real-Time Text RTT

Description

RTT (real-time text) is an accessibility standard that allows users to communicate during a phone call. This means that when you type a message, the other user can see that message as you are composing it. The feature is designed for users who are hard of hearing or have other impairments that make traditional audio calls challenging.
