Using the Avaya 3641/3645 IP Wireless Handset
Avaya 3641/3645/6120/6140 IP Wireless Handset SIP Administration Guide June 2012 71
When an incoming call occurs during an active call, the handset will play the second call
ringing sound until the call is answered, the caller hangs up, or the call transfers to
voicemail. If the END key is pressed, the first call is terminated and the handset reverts
to a full ring.
The active mode utilizes the most bandwidth and battery power. To conserve battery
resources, return the handset to the standby mode when a call is completed by pressing
the END key.
Push-to-talk (PTT) mode
The Avaya 3645/6140 IP Wireless Handsets utilize channels for incoming and outgoing
radio communication. While PTT is active, the handset is in PTT mode. It can receive
regular phone calls in this mode. When a regular phone call is answered, the handset
enters active mode.
Configuration menu mode
When user preferences are being configured in the Config menu, the handset is on but
is not active. If the handset is idle 20 seconds while in the Config menu, it will return to
the standby state. Calls can be received but cannot be answered unless you exit the
Config menu. If the handset receives an incoming call while in the Config menu, an
incoming call ringing icon is displayed and the handset starts ringing as soon as it
returns to the standby state.
Messaging mode
If text messaging functions have been programmed through the OAI server, as in a
nurse call system, the handset is able to receive text messages. While these messages
are being accessed, the handset is in messaging mode. Incoming calls will ring with the
second call ringing sound.

menu screens. The call status screen has the following format:
