RTT Calls and 911: A Brief History
For years, the FCC (Federal Communications Commission) has worked alongside phone providers and manufacturers to ensure that phones support texting technology.
As voice communications evolved toward wireless devices and networks, certain texting technologies couldn't keep up with smartphones. The FCC started working with emergency organizations, like NENA, to implement Real-Time Texting (RTT) technology for 911 systems.
What is an RTT Call for 911?
When an emergency arises, communication technologies such as Real-Time Texting can make all the difference. RTT 911 calls allow civilians in need of emergency response to send texts to telecommunicators as the situation unfolds.
The dispatcher receiving emergency information from a text message sent in real-time can read the message as it's being written and respond to it simultaneously. RTT calls remove the need to hit “Send,” unlike other types of text-based communications.
The bottom line: RTT mimics voice exchanges and provides phone users with disabilities or those in certain situations where calling is not an option with more accessible and streamlined emergency response communication.
How Do RTT 911 Calls Work?
With traditional texting technology, both the sender and recipient take turns communicating back and forth. Both users can see their text stream in conjunction with their speech during an RTT 911 call.
RTT calling features allow citizens to communicate with other wireless smart device users, such as:
Being able to reach and converse with various types of recipients can mean more effective communication and efficient emergency response solutions.
Like NG911 (Next Generation 911) systems, RTT features use IP (Internet Protocol) and cloud-based networks. These secure, interconnected networks mean fewer dropped calls when contacting 911 for assistance.
