Making and Receiving PTT Calls
This section describes the steps to make and receive Push-to-Talk (PTT) calls.
NOTE: On iOS 12.4 or higher devices, a call can be initiated only while the application is open
(visible). To start a call using a PTT accessory button, open the application first. To receive an
incoming call, you must bring the application to the foreground.

Making Calls
6.1.1
Making One-to-One (1:1) Calls with Automatic Call Answer
Procedure:
1 From the Contacts, tap the contact with whom you want to start a PTT call.
The Call screen is displayed, including the name of the contact that you are calling in the
Call Status.
2 Press and hold the PTT button. A private one-to-one PTT call starts, a chirp tone is heard,
and the PTT button changes color, indicating you have taken the floor.
3 Begin speaking.
NOTE: Some corporations may automatically assign a talkgroup called “all
subscribers group”. This talkgroup includes all the PTT subscribers from your
corporation.
4 Release the PTT button to allow the other person on the call to take the floor and speak.
5 Tap the End Call button to end the call.
6.1.2
Making One-to-One (1:1) Calls with Manual Call Answer
Procedure:
1 From the Contacts, tap the contact with whom you want to start a PTT call.
The Call Screen displays the name of the contact that you are calling in the Call Status.
2 Press and hold the PTT button. The call screen changes to a ringing state. A progress tone
is heard, and the PTT button changes color indicating the other user is being alerted.
3 Once the call is accepted, either the other user will talk or you can press and hold the PTT
button to talk. Talk when you hear the chirp tone and see the PTT button change color,
indicating you have taken the floor. If the call is rejected, the floor returns to the idle state.
NOTE: Some corporations may automatically assign a talkgroup called
“all_subscribers_group”. This talkgroup includes all the PTT subscribers from
your corporation.
4 Tap the End Call button to end the call.
