The Who-is-Who Directory In The Public Safety Industry

Your guide to public safety solution providers


nWise develops, sells, deploys and supports the MMX® Communication Platform, including MMX® RTT gateway. With the MMX®, Emergency Services can make and receive calls using Real-time Text (RTT), video and voice, and connect to third-party providers such as interpreter services or Video Relay Services. The MMX® enables services to receive calls from deaf, hard-of-hearing and deafblind individuals using Total Conversation. Our Communication Platform complies with EU requirements in the following legislation: EU Electronic Communication Code, Directive 2018/1972, recitals 14 on voice communication services, 35 on total conversation, and 258 on emergency communication.

The Coronacrisis, terrorist attacks in Europe, and recent natural catastrophes such as storms and floods in various regions brought to the forefront just how necessary a robust communications system for diverse, underserved communities, including the deaf, and those with speech impairment, are during a catastrophic event. Providing comprehensive, reliable and easy to use technology solutions that ensure that the deaf, deafblind and speech impaired communities have access to critical services at critical times is our purpose.

We have worked with RTT and Total Conversation (TC) since 2005, and the MMX® is used by 19 national services in 13 countries. Our team works with development, integration and implementation of RTT and TC calls to external communication platforms.

Our solution can be used as a gateway to connect RTT and TC calls to call takers in a PSAP. We integrate our solution to next generation 112 services, enabling deaf, deafblind and hard-of-hearing people to make emergency calls. Key information necessary in emergency services, such as geolocation, call recording, call logging, RTT conference, are all available in the MMX®. RTT calls to 112 can be made from Native RTT or Over-the-top apps that can be provided by us or a third-party supplier. If necessary, call takers at 112 can connect external resources to the call, such has video interpreter services.

Following is the high-level representation of the architecture, showing how our technology enables existing infrastructures to receive and make RTT and TC calls.

Regardless of the method used to access nWise MMX®, the communications streams are quite similar.

  1. An individual makes a DIRECT call to 112 (SIP)
  2. The call is connected to the next available telecommunicator in a pre-defined operator group that receives RTT calls.
  3. The nWise agent application automatically opens on screen.
  4. MMX® sends a SDP (session description protocol) with call information (SIP).
  5. SDP negotiation is initiated with IP- address and port information between the RTT-enabled user equipment and the agent application.
  6. Session is established between the two parties above – using RTT and voice (activated on the connecting device once the session is initiated) to communicate between the end user application and the telecommunicator position.
  7. If necessary, the telecommunicator incorporate a third party into the communication, for instance Video Remote Interpreter (3-party call). In this case, video is added to the call.

Our technology can be deployed as cloud-based or installed locally. Our team can work with local integration and installation on-site and/or remotely. Our apps are customizable and already available in more than 10 languages, including Arabic and Thai.
