Broadcasting Messages with Push to Talk
The Push to Talk (PTT) feature enables you to transmit messages and listen to replies much like a walkie-
talkie.
Your system administrator sets up the feature, defines up to 25 channels for PTT mode, and assigns a
label to each channel that easily identifies the channel, such as All, HR Dept, Shipping Staff, or
Executives. By default, you are subscribed to Channels 1, 24, and 25. This means that you can send and
receive PTT broadcasts on Channels 1, 24, and 25.
Each group or channel has one of the following priorities:
• Normal—By default, broadcasts sent to channels 1 to 23 are considered Normal broadcasts. If two
users begin a broadcast on the same group/channel at the same time, the phone with the lower
serial number continues to transmit while the other phone enters the receiving state. By default, all
phones are configured to receive broadcasts sent to channel 1.
• Priority—By default, broadcasts sent to channel 24 are considered Priority broadcasts. A Priority
broadcast interrupts Normal broadcasts or active calls. All phones receive Priority broadcasts
unless Do Not Disturb is enabled. Phones play Priority broadcasts at the phone's current audio
level.
• Emergency—By default, broadcasts sent to channel 25 are considered Emergency broadcasts. An
Emergency broadcast interrupts Normal broadcasts, Priority broadcasts, and active calls and plays
out at near maximum volume even if Do Not Disturb is enabled.
Send a PTT Broadcast
You can choose a channel to broadcast on before you send a PTT broadcast, or you can hold the Talk
soft key to immediately begin broadcasting on Channel 1, the default channel.
While you send a broadcast, you can pick up the handset, or press the Speakerphone or Headset
key and continue speaking. You can also press the Mute key to mute your audio so the people
receiving your broadcast do not hear anything. This behavior is similar to a phone call.
Tip: To automatically send a PTT broadcast on the default channel, press and hold Talk. After the
transmitting beep, begin speaking.
Procedure
1. Select Talk.
2. From the PTT Channels screen, select a channel.
A list is displayed with the default channel, the most recent channel you sent a broadcast on, and
other channels you can broadcast on.
3. Press and hold Talk to start the broadcast.
Be sure to hold Talk throughout the entire broadcast.
A transmitting beep is played and the phone displays the channel information.
4. Begin speaking.
5. When you finish your broadcast, do one of the following:
• Release Talk.
When you release Talk while sending the broadcast, the broadcast temporarily stops and
enters a 10-second waiting period. During this period, the channel remains open to give
others a chance to reply. At any time during the waiting period, you can resume your
