Receiving One-to-One (1:1) Calls
When you receive an incoming PTT call, the application is brought to the foreground, and the PTT
button changes color.
NOTE: Your phone responds differently to PTT calls based on the phone settings and PTT
application settings. For more information, see the
Interaction with Silent or Sound Mode on
page 65
section.
NOTE: This behavior assumes that Background Calling is turned OFF. For more details on
Background Calling, see the
Call Behavior in Background on page 65 section.
Whenever the talker releases the floor, the PTT button changes color and the floor is available for
another talker.
You can continue the conversation by touching and holding the PTT button on the screen.
Tap the End Call button to end the call.
6.2.2
Receiving Broadcast Talkgroup Calls
An incoming broadcast talkgroup call looks like any other talkgroup call but preempts other PTT calls
in progress, except emergency calls. You can recognize a broadcast talkgroup call because a
distinct tone is played, followed by an announcement. During the call only the broadcaster can
speak, and you cannot take the floor. These calls also override your Do Not Disturb (DND) status if
your administrator has set the talkgroup to do so.
Only designated talkgroup members may make broadcast talkgroup calls. If you are not allowed to
make calls to a talkgroup, you will not see it listed in the Talkgroups tab. If you try to call a
broadcast talkgroup from History, you see a message indicating that the call cannot be completed.
