Push-to-Talk Conference Call

Note: The Push-To-Talk function requires a Multi Point Control Unit (MCU), handsets
programmed with PTT settings (from the PDM) and that groups have been created in the
system.
The push-to-talk (PTT) function can be described as a group/conference call. A PTT session
can be triggered from the system, by an alarm or by a user that sends an invitation to a
PTT group from the handset.

with the others, he simply presses and holds the Mute button to open the microphone.
More than one handset can press the Mute button and start transmitting at the same
