NOTE: This feature is not available on the Model 8664 or 8668 endpoint.
The Push-to-Talk (PTT) feature allows Model 8665 users to broadcast and receive
voice messages among the PTT group by broadcasting the message on a shared chan-
nel, similar to the way a handheld, two-way radio operates. The endpoint supports
eight multicast channels with the current channel saved in memory on the endpoint
(see
page 73 ).
When a member of the PTT group broadcasts a message, all members of the group
that are monitoring that channel will hear the transmission. A low-volume ring
announces the incoming call, and a system message is displayed. When you or
another member terminates a broadcast session, the endpoint remains in the receive
state.
To initiate a PTT broadcast:
1. Press and hold the Talk button and wait briefly to activate the channel before
talking.
2. You may begin talking when the display shows “Transmitting.” The display
screen shows the current active channel, and the “start transmit” sound is played.
3. Hold the endpoint two inches from your mouth and talk into the microphone.
When the Talk button is released, the endpoint then enters the waiting state
where it monitors the channel for up to ten seconds.
To receive a PTT call:
Upon receiving a PTT transmission, the phone plays the “receiving alert” sound and
enters the receive state.
In this state the phone receives all conversations on the selected channel. The phone
will ignore the Talk button while in the receive state. The screen shows the current
active channel, the caller ID information of the current transmitter, and an indication
that the phone is receiving a broadcast transmission.
At the end of a transmission, the phone enters the waiting state where it monitors the
channel for up to ten seconds and displays “Waiting” on the screen. If no other trans-
mission occurs within ten seconds the phone reverts to idle state.
