Emergency Calls
Emergency calls are then only transmitted via external connections/
providers/accounts on which emergency call ability is enabled. If the phone
cannot make an emergency call, the subscriber is informed by an
announcement.
Emergency calls can be configured to take priority over other calls. If
necessary, a call can be interrupted to enable an emergency call to be
made.
The phone number is always sent along with an emergency call. If number
presentation suppression is switched on, it is disabled automatically when
the emergency call is made.
Note: Local service numbers, such as numbers for doctors or local
authorities are also increasingly being added to the emergency
numbers. These service numbers can also be set up in the PBX and, like
emergency numbers, dialled either with or without the exchange line
access number, depending on the configuration. However, calls to
service numbers are not handled like emergency calls. If you want to
prevent service numbers from being dialled (e.g. to an external
subscriber on the same PBX), set up a call restrictor for each individual
service number.
