What is rtt calling?

RTT calling, or Real-Time Text, is a feature that transmits text instantly as it is typed during a phone call. It's particularly useful for people who are deaf, hard of hearing, or have speech disabilities. Here's some key information:

• How it Works: RTT converts typed text into audio signals during a call, allowing the recipient to read the message in real-time, character by character. This eliminates the need to wait for the entire message to be composed and sent, as with traditional text messaging.

• Accessibility: The primary benefit of RTT is enhanced accessibility for people with hearing and/or speech difficulties. It provides a more natural and immediate form of communication compared to relay services or TTY (Teletypewriter) devices.

• Comparison to TTY: RTT is considered a more advanced and efficient technology than TTY. TTY requires specialized devices and relies on audible tones to transmit text, making it slower and less convenient. RTT uses digital signals and integrates directly into modern smartphones.

• Availability: RTT support depends on the mobile carrier and the devices used by both the caller and the recipient. Most modern smartphones now include built-in RTT functionality, but it might need to be enabled in settings. Network compatibility is also crucial.

• Legal Compliance: In many regions, RTT is part of accessibility mandates for telecommunications services. This ensures that carriers provide accessible communication options for all users. For example, see the section about how accessibility is improved through RTT.

• Using RTT: RTT is often used in situations where immediate communication is essential. For instance, it can be helpful when calling emergency services or for situations requiring live updates. To find more info about emergency%20services you can search in the given link.
