Broadcasting Messages Using Push-to-Talk and Group
Paging
The Group Paging and Push-to-Talk (PTT) features enable you to broadcast a
message to as many people as have subscribed to a channel or have been
placed in a group. Your system administrator can set up both features on your
phone.
Group Paging mode enables you to broadcast a one-way announcement to
people subscribed to a paging group. The people receiving the announcement
can’t respond to the message.
PTT mode enables you to broadcast a message to people subscribed to a
channel. The people receiving the message can respond to the message by
broadcasting a message over the same channel. In this way, PTT is a
collaborative broadcast mode.
Your system administrator can define up to 25 Paging Groups (for Group
Paging mode) or Channels (for PTT mode). Your system administrator may
assign a label to each group or channel that easily identifies the phones in the
group or channel (for example, All, HR Dept, Shipping Staff, or Executives).
Each group or channel will have one of the following priorities:
Normal (for Groups/Channels 1-23)—Broadcasts sent to Groups/Channels 1
to 23 are considered Normal broadcasts. When a phone receives more than one
Normal broadcast, the first broadcast received is accepted, and all others are
ignored (not played and not stored). By default, all phones receive broadcasts
sent to Group/Channel 1.
Priority (for Group/Channel 24)—Broadcasts sent to Group/Channel 24 are
considered Priority broadcasts. All phones receive Priority broadcasts unless
Do Not Disturb is enabled. If a phone receives a Priority broadcast while an
Emergency broadcast is already playing, the Priority broadcast is placed on
hold. Phones play Priority broadcasts at the phone’s current audio level.
Emergency (for Group/Channel 25)—Broadcasts sent to Group/Channel 25
are considered Emergency broadcasts. All phones receive Emergency
broadcasts (even if Do Not Disturb is enabled), and play them immediately. By
default, phones play Emergency broadcasts at the highest audio level. The
audio level will return to normal for subsequent non-Emergency broadcasts.
Push-to-Talk Mode
Your phone may be enabled to operate in a broadcast mode called
Push-to-Talk (PTT). In PTT mode, you broadcast messages on a specific
channel. In order to send and receive PTT broadcasts on certain channels, you
have to subscribe to those channels.
PTT broadcasts are collaborative: you can transmit messages and listen to
replies.
