Other The Push-to-talk feature allows the IP Touch 610 WLAN to operate in a push-to-talk (PTT) group broadcast mode in addition
to the standard telephone operation.
The IP Touch 610 WLAN telephone supports 8 multicast channels. The channel used is saved in the telephone memory. A PTT
call is initiated by pressing the Talk button located on the right side of the handset. All IP Touch 610 WLAN monitoring that
channel and that have enabled the PTT feature in the user preferences menu will hear the transmission through group listening..

'Push-to-Talk' function).

7.4 Making a call on another channel
You may need to make a call on another channel than the one defined by default. You must first subscribe to new channels.
7.5 Receiving a 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 key 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. During a 'PBX' conversation, the IP Touch 610 WLAN is not able to receive a PTT transmission. At the
end of a transmission, the phone enters the waiting state where it monitors the channel for up to 10 seconds and displays 'Waiting'
on the screen. If no other transmission occurs within 10 seconds the phone plays the 'end call' sound and reverts to idle state.
