Using Push To Talk (Ptt) - Avaya 3600 Series User Manual

5.7.2 Using Push to Talk (PTT)

Call Period
The two-way radio operates on the concept of a push-to-talk (PTT) session or call period. The PTT call period begins with
the first transmission and ends when there has been no two-way radio traffic on the channel for ten seconds.
The PTT mode controls the keypad during a PTT call period. Therefore, it is not possible to use the keypad for any other
function (for example, accessing the on-hook menu or accessing an OAI application) unless the PTT call is terminated. It
is possible to place a PBX call.
Note
In this section, Talk refers to the PTT button located on the right side of your 3626 phone.
·
To initiate a call:
Press Talk and wait briefly for the channel to activate. When Transmitting is displayed, begin talking.
·
Transmitting
When a call has been initiated, hold the phone two inches from your mouth and talk into the microphone. When Talk is
released, the phone enters a waiting state, where it monitors the channel for up to ten seconds.
If no transmission occurs during the ten second countdown period, the phone reverts to idle state.
To initiate subsequent transmissions:
Using any 3626 phone using the same channel, press Talk and begin talking. The display shows the current active
·
channel.
Receiving
When your phone receives a PTT transmission, a 'receiving alert' sound plays and the phone enters receive state.
In this state, the phone receives all conversations on the selected channel and ignores Talk. The display shows the
current active channel, the caller ID information of the current transmitter and an indication that the phone is receiving a
broadcast transmission.
The caller ID is protocol specific. In most cases, it is the extension number programmed in the phone from the on-hook
user menu.
At the end of the transmission, the phone enters the waiting state where it monitors the channel for up to ten seconds
and Waiting is displayed. If no other transmission occurs within ten seconds, the phone reverts to idle state.
To change the PTT volume:
Press Up or Down (on the left side of the phone). A separate volume is maintained for PTT calls with the current
·
volume selection retained in memory.
To mute a PTT call:
Mute only affects the current call and the phone will play subsequent PTT calls. Mute does not allow you to use the
phone's keypad for anything else, including an OAI application.
1. To mute a current call, press Mute.
2. The prompt Mute Two-Way Radio? is displayed. Press either Yes or No. If you do not confirm either Yes or No,
the prompt disappears after three seconds.
3. While in the mute state, Mute turns into UnMute on the display and you can choose to unmute the PTT call (the
confirmation prompt is displayed first). When the next PTT call period starts, the audio is automatically unmuted.
