DAMM TetraFlex® PTT is developed, owned and maintained by DAMM Cellular Systems. It is a vendor and technology-independent soft terminal, tailored for secure and private communication.
It is a purely IP-based solution requiring no radio gateways and operating independently of any radio infrastructure.
DAMM PTT can be fully integrated into a DAMM system and thereby be used with all DAMM TetraFlex Gateways and applications, such as the Voice and Data Log System or Dispatcher.
DAMM TetraFlex PTT includes features like:
- PTT group calls between other PTT apps, TETRA, DMR & analog terminals and dispatchers
- PTT group calls to bridged PMR systems connected via DAMM TetraFlex Group Bridge
- PTT key on touch screen or via headset or Bluetooth button
- Individual simplex and duplex calls between other PTT apps or dispatchers or TETRA, DMR and analog terminals
- Duplex calls to telephones connected via DAMM TetraFlex Voice Gateway
- Optimized bandwidth consumption using ACELP/TETRA voice codec
- Video streaming to other PTT apps or DAMM Dispatchers
- SDS text messaging between PTT apps, TETRA and DMR terminals, dispatchers and other compatible devices
- Image transfer to and from other soft terminals and DAMM Dispatchers
DAMM PTT registers itself to the DAMM TetraFlex Terminal Gateway via any IP network such as Wi-Fi or 3/4G networks.
Voice communication
With the DAMM PTT it is possible to listen to and talk in group calls as well as initiate or receive full individual duplex calls. Up to seven different talk groups may be scanned simultaneously, and it is possible to listen to two audio streams at the same time.
The order of the groups can be arranged on the main group screen and it is possible to choose whether the PTT button should call the last active group or the main designated PTT group. Groups can be muted/unmuted at any time.
Individual calls can be established by typing the user number, ISSI or unified number of the called party. The phonebook updates directly from the subscriber register.
Use-case examples:
- Coverage extension for voice calls – ideal for workers commuting between sites and employees in remote offices
- Low-cost alternative to expensive TETRA terminals for non-critical usage
- Picture and video transmission for improved workflow
- Easy sharing of status information and fleet management across a nationwide network
