Push to Talk app

Push to Talk overview

If enabled by the administrator, your phone can operate in a group broadcast mode that is called Push to Talk (PTT). In PTT mode, the phones behave like walkie-talkies. Your phone transmits audio over a built-in speakerphone and recipients can respond to your message.

The administrator subscribes you and others to any of the 25 normal channels that are available. The administrator may give you permission to receive, and optionally send, PTT broadcasts in your subscribed channels. The administrator creates a label for channels to help you identify PTT channels. The default label for channel 1 is ALL. Examples of normal channels in a hospital setting may be: Channel 2: Maintenance, Channel 3: Hospital Admitting, and Channel 4: IT Helpdesk.

Your phone alerts you to PTT transmissions from normal channels, the priority channel, and the emergency channel. Your phone receives PTT transmissions differently depending on whether you are on an active call.

  • If you are not in a call, you automatically hear the PTT beep and the audio broadcast.

  • If you are in a phone call, you do not hear the PTT beep or audio broadcast.


Note


If you are on a call and see the PTT notification, you may join the broadcast, which would put your call on hold.

Change the default PTT channel

Your default PTT channel is the one that you automatically transmit on when there are no ongoing conversations on another PTT channel. In the PTT app, the default channel has a star icon next to it and has orange text.

Before you begin

Ensure that you have transmission permissions on your desired default channel.

Procedure


Step 1

Access the PTT app.

Step 2

Click the Channels tab.

Step 3

Tap and hold the channel button that you want to be your default channel.

Step 4

Tap Set as Default Channel.


Change channel subscriptions

Only the channels that you’re subscribed to display in your PTT app. Only the administrator can change what channels display.


Note


Your administrator controls PTT channel subscriptions. You can see which channels you’re subscribed to and which you can transmit on, but you can’t change or add to the list.


Procedure


Contact your administrator to change your subscriptions and transmission permissions.


Send a PTT broadcast

You can send PTT broadcasts over your default PTT channel, or over a different channel. For example, you may want to send a broadcast over an active PTT session that is on a different channel than your default channel.

When you’re done speaking and release the PTT button, the phone enters a ten-second wait period. During this time, the channel is open to receive or send more broadcasts. If no activity occurs within the wait period, the PTT session closes. The wait period keeps the channel open and gives anyone subscribed to that channel time to join the conversation.

Before you begin

If your phone is password-protected, unlock your phone to send a PTT broadcast.


Note


For release 1.3(0) or later, your administrator may change the settings so that you can send a PTT broadcast without unlocking your password-protected phone. Check with your administrator for more details.


Procedure


Step 1

If you’re not on the desired channel, access the PTT app and tap the desired channel from the Channels tab or click a leg of a conversation from the Activity tab.

Step 2

Press and hold the programmed PTT button.
