Chapter 5: Push-to-Talk (PTT) and Paging

The Push-to-Talk and Paging features enable you to call as many people as have subscribed to a channel
or placed in a group. Your system administrator programs both features and determines the best way to
deploy these features in your facility. Contact your system administrator if you need help with these
features.
You manage both features in the Settings menu. Navigate to Settings > User Settings > Preferences >
Paging/PTT Configuration for the configuration options.

Push-to-Talk

SpectraLink 8430 / 8440 Wireless Telephones can operate in a group broadcast mode called Push-to-
Talk (PTT). Users must subscribe to channels to receive PTT broadcasts. In PTT mode, the handsets
behave like walkie-talkies: a single handset can transmit to multiple listeners.
If the system administrator has disabled PTT, the PTT options will not display in the Settings menu.

Receiving and Transmitting PTT Broadcasts

Press and release the Talk button to display the default channel, the last channel you used, any
additional subscribed channels, and the Priority Channel.
Press and hold the Talk button to open the default PTT channel for transmission. Release the Talk
button to end the transmission and await reply. The handset will wait for ten seconds before reverting
to standby mode. The wait period keeps the channel open and gives any handset receiving that channel
time to join the conversation. To open a different channel or to send a new broadcast within the wait
period, you must end the wait period on the current channel by pressing the End key.
