• 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.
