The Push-to-talk (PTT) feature allows your phone to operate in PTT group broadcast mode as well as in standard phone mode.
The Push-To-Talk (PTT) function can be described as a group/conference call to a predefined group of members. All incoming,
outgoing, missed or unanswered PTT calls are added to the call list/missed calls with a PTT text.
9.1
Push To Talk (PTT) Group call
The calls are made in half-duplex communication using the Push To Talk button as a momentary switch button. While one user
talks (and the PTT button is pressed) the others can listen. The microphone is active when the PTT button is pressed down and
on mute when the PTT button is released.
• Start a PTT group call
Once a member tries to call the other members of the PTT Group by pressing the PTT button, the others receive an invitation
to participate on their phone. The user can also send a message (as text message) to invite others to join the discussion.
