The Hamilton RTT Solution is Here!

Real-Time Text (RTT) is a core feature to the Next Generation 9-1-1 (NG 9-1-1) model enabling text-based communication in a way that is superior to traditional SMS Texting communications. RTT allows text to be transmitted while it is being typed.

NG 9-1-1 with RTT capability is a modern solution to provide the American public options for calling 9-1-1 and enabling Public Safety Answering Points (PSAPs) faster communication capabilities for emergency calls.

This technology delivers greater communication access for the public safety industry, those who use Relay services, as well as the greater population. The earlier the RTT adoption, the smoother the learning terrain and the sooner states, PSAPs and the public may benefit from this innovative technology.


Real-Time Text (RTT) begins with two parties engaging in a phone call to each other, with both parties using an RTT capable device. Due to immediate transmission of typed characters, RTT has the same conversational directness and interactivity as voice.

How RTT to 9-1-1 Works

In addition to having the foundations in place to support RTT, NG9-1-1 PSAPs need to have their networks interconnected with wireless carriers so that calls to 9-1-1 are end-to-end IP based.
