The DAMM TetraFlex® PTT App is an application running on Android devices enabling users to log on to the DAMM TetraFlex® network as a registered soft terminal (client) being a fully integrated part of the TetraFlex® communication system.

Note: Without an existing TetraFlex® infrastructure you cannot use this application.

The TetraFlex® PTT App registers in the TetraFlex® system similar to other TETRA or DMR terminals with its own SSI number and user number set up in the Subscriber Register with a Profile associated and with defined Group(s).

The TetraFlex® PTT App does group calls and it does communicate to all terminal types of the subscriber register. This includes also the new unified numbering, allowing call forwarding or simultaneous ringing of different devices.

The TetraFlex® PTT App uses similar features as already know by the DAMM Dispatcher. Users may therefore already be used to functionality and operation.

Functions and Features
The TetraFlex® PTT App supports the following modes of communication:

1. Can make and receive group calls to and from TETRA or DMR Radios, other soft terminals, DAMM Dispatchers and other compatible units connected to the DAMM TetraFlex® infrastructure.

2. Simplex and Duplex calls with TETRA or DMR Radios, other soft terminals, DAMM Dispatchers and other compatible units connected to the DAMM TetraFlex® infrastructure.

3. SDS to and from TETRA or DMR Radios, other soft terminals, DAMM Dispatchers and other compatible units connected to the DAMM TetraFlex® infrastructure

4. Protection against accidental activation of the PTT button.

The TetraFlex® PTT App as a fully integrated part to the DAMM TetraFlex® system can thereby access all TetraFlex® gateways and can be monitored and recorded by the TetraFlex® Voice and Data Log system.
