Push to Talk Overview
If enabled by the system 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 system 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.
If you are on a call and see the PTT notification, you may join the broadcast, which would put your call on hold.
