Emergency Calls
If configured in the WinPDM/WSG DM, up to five different phone numbers can be reserved for
emergency calls. These numbers can always be called even when the phone- or key locks are
active. For more information, please refer to the Configuration Manual, Unify OpenScape WLAN
Phone WL4.
Emergency Ring Signal
A separate ring signal for incoming emergency callback calls can be configured in the WinPDM/
WSG DM. It is used to distinguish the emergency ring signal from other handset ring signals.
When an emergency call is made from the handset, it first goes to a emergency center which
in turn switches the call to the appropriate emergency service. This local emergency service
then calls back to the handset user, who can identify the incoming call by this specific callback
emergency ring signal.
Call Services
NOTICE:
The
Call services
menu provides access to PBX dependent function-

default Call services function, 16 extra system specific call services can be de-

the handset starts up, or when it shuts down.
