Receiving a call

8.5
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.
