Avaya 1230 - Characteristics of Emergency Calls

Characteristics of emergency calls
The user does not have to log on to make an emergency call.
During an emergency call, the user:
• cannot make outgoing calls.
• is not notified of incoming calls and cannot accept incoming calls. Incoming calls receive a call
waiting tone.
• cannot transfer, join, or conference the emergency call, place the emergency call on hold, or
park the emergency call.
• cannot receive an incoming call.
• cannot auto-retrieve a parked call and auto-retrieval of parked calls is not displayed.
• cannot disconnect the emergency call in most cases. Only an emergency center or operator
can disconnect the emergency call. If the user attempts to disconnect after the call has been
made, the IP Deskphone switches to loudspeaker. If the loudspeaker mode is already on, the
connection remains.
Note:
If E911_TERMINATE_ENABLE is provisioned, then the caller can terminate the call to
emergency services even after the connection has been made.
• cannot change Audio Quality.
• can reply to IM pop-ups, which are operational during an emergency call.
During an emergency call, the keys function as follows:
• the Services, Inbox, Outbox, and Address Book keys are all disabled.
• a right click of the mouse does not show the services menu.
• the conspicuous keys are disabled.
• the mute key and hold key are disabled.
• the increase and decrease volume keys remain functional.
• the feature keys are visible and all except the speed-dial keys are functional.
Shut down and restart
If the IP Deskphone turns on or off, the IP Deskphone restarts in the usual way, reads the config
file, and receives the location information through LLDP-MED or DHCP protocols (from the Layer 2
switch or DHCP server, which must be available and properly configured). Otherwise, the
IP Deskphone is not provided with valid location information and cannot transmit that information
when making an emergency call.
