Using the Push-to-Talk Feature
Spectralink 84-Series handsets can operate in a group broadcast mode called Push-to-Talk (PTT). With PTT, the
administrator enables channels and users are subscribed to some or all of these channels to receive and send
PTT broadcasts. In PTT mode, the handsets behave like walkie-talkies: your handset transmits audio over a built-in
speakerphone and recipients can respond to your message. Your system administrator defines which PTT channels
are available for subscription. By default, subscriptions to Channels 1, 24, and 25 are enabled. Contact your system
administrator for more information.
This section shows you how to send and receive PTT broadcasts, and how to configure PTT. If the system
administrator has disabled PTT, the PTT options will not display when you open the Settings icon from the Home
screen.
There are three PTT channel types:
•
Normal Channels
PTT Channels 1 to 23 can be used as normal channels by any subscribed handset user. The
administrator can create a label, comprised of up to 15 characters, for Channels 1 to 23 to help users identify PTT
Channels. The default label for Channel 1 is ALL.
Normal Channels are allocated to various groups of users and recipients. Examples include channel 2 for the
maintenance group, channel 3 for Hospital Admitting, channel 4 for the IT Helpdesk.
•
Priority Channel
Users subscribed to the Priority Channel will receive transmissions on the Priority Channel
unless Do Not Disturb is enabled or an Emergency page is already playing. The Priority Channel plays transmissions
at the current audio level. The default Priority Channel is 24.
•
Emergency Channel
Every handset will receive transmissions on the Emergency channel even if the
handset is in an active call or if Do Not Disturb is enabled. Emergency transmissions play out on the speaker at the
highest audio level. The audio level will return to normal for subsequent non-emergency transmissions. The default
Emergency Channel is 25.
