When the emergency call function is enabled in the configuration file, the
emergency number is shown in the log on menu. When the user lifts the
handset the dial tone is heard although the phone is not logged on.
When the user dials the emergency number, the phone uses the IP trunk
interface to establish the call. The Setup is sent directly without any
admission check.
The A-number defined in the configuration file is sent. The number sent
to the public exchange must be within the direct-in-dialling number
series, otherwise the public exchange will replace this number.
After the emergency call is terminated the phone returns to the not
logged on state. The emergency centre can call back to the terminal
although it is logged off.
It is possible to define a first and a second choice for the emergency call
server in case of that the first choice fails.
Note:
As soon as the emergency number is defined in the configuration
file, the log on menu in the phones indicates that it is possible to
dial the emergency number. But it is very important that the emer-
gency number is set up in the PBX and tested before it is enabled
in the IP phones.
Note:
Verify that it is possible for the alarm centre to call back to the
number that is sent as the A-number. One possibility is that the
number is answered by the PBX operator.

Monitoring key (MNS key)
It is possible to monitor other extensions from programmable function
keys on the IP phone. This function is also called MNS (Multiple repre-
sented directory number with dial-by-function key) and is often used in
Boss-Secretary applications.
The Monitoring keys are initiated in the PBX. The only changes that can
be done by the end-user is the changing of the type of ring signal for the
Monitoring key. The only parameter that can be changed in the configu-
ration file is the delay time before the ring signal is generated for the
Monitoring keys, see the description for
