Innovation by nWise, character by character

The nWise RTT bridge: Your path to total NG112 accessibility.

Silence is no longer a barrier

In an emergency, every second counts, and every character matters. For 20 years, nWise has been the authoritative voice in accessible communications, ensuring that “Total Conversation” isn’t just a technical term — it is a reality for our customers.

Designed for the modern PSAP

The nWise RTT bridge is designed for the modern PSAP. We have built the technology that bridges the gap between legacy systems and the future of NG112, making sure Emergency Communication Services is as inclusive as it is efficient.

The industry benchmark

Compliance rather than complexity

The nWise RTT bridge is the industry benchmark for NG112 compliance, seamlessly bridging the gap between PSTN and IP. We handle the technical details, allowing dispatchers to focus on their mission-critical work.

Real-time is the only time

In a crisis, waiting for a "Send" button is a luxury no one has. Our technology transmits text character-by-character, in real-time, exactly as it's being typed. It's fast, it's intuitive, and it's the most effective way to communicate when voice isn't an option.

A seamless leap forward

Our RTT bridge is engineered to integrate smoothly with existing infrastructure, providing an upgrade to your PSAP's capabilities.

The technology behind our solution

The nWise RTT bridge is a modular, SIP-based solution designed to integrate Real-Time Text (RTT) directly into the Next Generation Core Services (NGCS). It acts as the intelligent link that allows PSAPs to handle RTT calls with the same fluidity and urgency as traditional voice calls, ensuring “meaningful accessibility” for the Deaf, speech impaired, and Hard of Hearing communities.

Technical Core & Capabilities for the nWise RTT bridge

Protocol interoperability

Provides standards based and reliable integration of RTT calls into existing SIP-based architectures and NG112/NG911 environments. It enables RTT to function natively within the core network, bypassing the need for legacy relay service interfaces.

Standardized compliance

Built for global authority, our RTT-bridge has been developed to conform with the EECC 2018/1972 and EAA 2019/882 requirements, and to meet the ETSI EMTEL and NENA i3 requirements.

Multi-party RTT conferencing

A standout feature in emergency scenarios, the bridge supports both two-way and multi-party RTT calls. This allows for "warm transfers," enabling dispatchers to bring in specialists or supervisors while maintaining a continuous, real-time text stream between all parties.

Flexible integration

Offers modular integration via SIP or REST API, minimizing operational disruption and infrastructure costs while providing a scalable path to full NG112 compliance.

Most legacy systems are voice-centric; the nWise RTT bridge makes them data-centric. By eliminating the “send” button and transmitting characters instantaneously, it removes the critical delays inherent in standard SMS or chat. For a PSAP, this means faster time to dispatch and a more inclusive service that treats every citizen’s call with equal priority.
