The Push-to-talk feature allows the Mobile IP Touch 610 WLAN to operate in a push-to-talk (PTT) group broadcast mode in addition to the standard telephone operation.

The Mobile 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 Mobile 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.

PTT dialogue is interrupted when you answer a PBX call. When the PBX call is ended, PTT dialogue resumes if in an active call. The 'Push-to-talk' function, activated by the system administrator can be configured by the user via the set local menu (OK key, 'Push-to-Talk' function).

8.5 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 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.
