In today’s digital landscape, communication is increasingly inclusive, allowing for real-time, text-based exchanges that cater to users with different needs and preferences. Real-Time Text (RTT) is an essential technology within the IP Multimedia Subsystem (IMS), designed to facilitate text conversations as they happen, character by character. Originally developed to replace legacy TTY systems, RTT offers a universal solution for the deaf, hard of hearing, and anyone who prefers real-time text over traditional voice calls.
