RTT Call Meaning: What does RTT calling mean?
RTT calling, short for Real-Time Text Calling, is a feature available on Samsung Android phones that enables users to engage in text-based conversations during phone calls without the need to press “send” for each message. Unlike traditional texting, where messages are sent after composing, RTT calling transmits text instantly as it’s typed, allowing recipients to view messages letter by letter.
However, this feature’s availability relies on carrier support, requiring both parties to have compatible devices and network providers that support RTT calling. It offers an inclusive communication option, especially useful for those who prefer or require text-based interaction.
What is RTT calling on Android?
RTT calling for Android was introduced to help people who have trouble speaking or hearing on phone calls. This feature allows them to talk through text messages. It sends the words you type instantly to the person you’re talking to.
To use RTT, you need a special phone like an iPhone or Android that uses a certain kind of technology on networks that support RTT. RTT calling uses a lot of network resources, similar to conference calls and Volte.
Back on December 31, 2017, the FCC (a group that makes rules for communication) told all phone companies to make networks that work with RTT. They did this by creating a thing you can download called an APK or plugin.
RTT is a newer version of something called TTY, which only worked on landline phones and was primarily used by tty users. But with RTT calling, you can use it on any kind of phone, whether it’s wireless or fixed. Now, let’s learn a little bit about TTY.
What is TTY calling?
TTY calling, also known as teletypewriter calling, is an older method of text-based communication over phone lines. It refers to an early communication technique that allowed text-based conversations over fixed landline telephones. It involves the use of tones and protocols to transmit and receive text messages, primarily using teletypewriter devices. Primarily used by individuals with hearing or speech impairments, TTY calling has been largely replaced by RTT calling due to its real-time nature and smartphone compatibility. However, some phone providers still support TTY calling.
However, as technology progressed and wireless phones became commonplace, TTY calling faced limitations. The transition to wireless posed challenges for traditional TTY devices, leading to the development of more advanced solutions like RTT (Real-Time Text). RTT evolved to accommodate the needs of a modern, mobile-centric society, allowing text-based communication in real-time during phone calls. While TTY calling served as a pioneering method, the evolution to RTT better aligns with the convenience and capabilities of today’s communication landscape.
How does an RTT call work?
An RTT (Real-Time Text) call operates by allowing users to send messages instantaneously to the recipient without relying on a separate “send” button. This functionality proves particularly valuable for individuals with speech or hearing challenges.
RTT Calling Uses
Unlike many accessibility solutions, RTT calling is designed to work seamlessly for RTT users and doesn’t necessitate any external attachments to the phone. It can function across various networks and devices.
Essentially, RTT empowers users to communicate through real-time text on wireless phones, providing enhanced accessibility and adaptability with the use of emojis.
During an RTT call, users can observe their text messages appearing alongside their spoken words, offering a synchronized communication experience. This feature contributes to a more inclusive and seamless interaction for those who benefit from text-based communication.
How is RTT different from instant messaging?
RTT and instant messaging serve as two distinct forms of text-based communication, each catering to specific scenarios. In the era of smartphones, instant messaging platforms have become a lifeline for those with hearing impairments, enabling them to communicate via text without time constraints.
