Device Communication

There are two ways to communicate when operating the PTT Express client: Group Call and Private Response.
Depending upon the device and the PTT Express client configuration, these can be hard buttons on the device or soft buttons.
  • Group Call: Press and hold to start communicating with other voice client users.
  • Private Response: Press and hold to respond to the originator of the last call.
Buttons on the device can be configured to perform various functions. Contact your system administrator for exact button functionality.

While a PTT communication button is pressed the user will not be able to use other device buttons to perform separate tasks. In general, pressing multiple buttons simultaneously leads to inconsistent PTT Express client behavior. Also, when the PTT Express client is installed on a mobile computer, the action button is no longer available.
