Silentel 7.4: Enhanced Push-to-Talk functionalities

We’re happy to inform you about new Silentel update with enhanced Push-to-Talk (PTT) functionalities and further users' improvements.


What’s new in Silentel 7.4

Ardaco has a long history with government organizations communication. Already in 2012 being a technical leader in the largest public safety R&D European project SECRICOM - involving several partners and public safety organizations from many EU countries. Ardaco built up a PTT communication platform connecting all organizations involved in public safety, such as police, military, fire brigade, ambulances, hospitals, crises management centres, local county and central government representatives across several countries. The whole PTT solution connecting all government organizations was based on Silentel technology.

Incoming Push-to-Talk enhancements in Silentel

Two years ago, Silentel introduced unique secure conference platform which provides real-time voice and data communication between two and more users in two different modes:

  1. Conference with automatic voice detection – the voice of the participant starts playing automatically when he starts talking.
  2. Push-to-Talk with classic push button control – the voice of the participants starts playing after pushing PTT button.

In the new Silentel version with enhanced PTT functionalities, Silentel remains for users as it was before, with all of its features, such as secure calls, conference calls, chat and file transfer. In addition, Silentel provides secure group communication as classic PTT functionality exactly in the same way as police and other public safety responders know it and are used to it. PTT calls can be done with easily defined groups of unlimited number of users.

Another benefit for users is the possibility to use with any standard Bluetooth devices such as headsets, microphones, or push to talk buttons and other communication or surveillance equipment. In this way Silentel provides flexible and comfortable hands-free operation for its users. An example of a PTT button which the user can comfortably carry on his wrist, finger, attached to uniform or on the car steering wheel is on the picture below.
