This is the core functionality of any two-way radio system. Push-to-Talk (PTT) allows a single person to reach hundreds of users, organized in groups, with a single button press. TASSTA supports PTT group calls over high-speed IP networks and provides superb audio quality. With T.Rodon, it’s possible to make multiple group calls and see all users on the network on one or more screens.

This type of call allows users to communicate privately outside a group. A one-to-one simplex call is easy and fast to set up; this feature gives dispatchers a means for secure user-to-user simplex voice communications with the press of a button. A private message can be conveyed between a user in the field and the dispatch point. The user rejoins their groups when the personal call is completed.

The Emergency Call feature is designed to keep the T.Flex user safe and in contact with help. Help is often dispatched from the T.Rodon dispatch location. Used in conjunction with the T.Flex application, the T.Rodon dispatcher software will give you a visual indication, sound emergency alarm tones and put through voice calls from the user in distress. If GPS is enabled, you will also see the location of the person initiating the emergency, be able to reorganize the locations of others and dispatch the closest or most appropriate users to provide support. T.Rodon keeps the situation in control.

T.Flex can operate one-to-one video calls, which the recipient can either accept or decline. The video call includes all the most regular functions like switching rear / front cameras and selecting the preferable speaker sound output and turning off the camera, microphone and speaker. Users can speak simultaneously

The application provides real-time exchange of free-form text messages among individual users or groups. The addressee of your message gets an instant notification (tone and icon). Messages are color-coded to indicate if they have been read. Offline users receive their messages immediately when they reconnect to the network.

TASSTA communication platform records the full history of users’ activity, including the missed calls, messages, availability and voice communication. The system can maintain call records on the network for months’ worth of voice communication among users. The activity tracking is centrally managed through the centralized administrative interface of T.Commander, putting you 100% in control of the network.

It is a specialized feature in T.Mugen that enables web-based monitoring of predefined patrol routes. As users equipped with T.Flex devices move between assigned checkpoints set up via the Map Tool, operators using T.Mugen can oversee their progress in real time—all from a standard web browser. This allows for efficient route management, incident tracking, and improved accountability, without the need for dedicated dispatch software.
