Emergency Calls
The emergency numbers set up on the PBX are used for emergency calls. These calls are handled in a special way.
Depending on the configuration, emergency calls can be made either with or without dialling the exchange line access number. This has the benefit that even people who don't know how to use exchange line access numbers can make emergency calls.
A system phone can also be used to make emergency calls if the screen lock is switched on (optional, see phone's instructions).
Users who cannot usually make external calls can make emergency calls if the appropriate exchange line authorisation is enabled.
* Note: If you want to prevent emergency numbers from being dialled (e.g. to an external subscriber on the same PBX), set up a call restrictor for each individual emergency number.
Emergency calls are then only transmitted via external connections/providers/accounts on which emergency call ability is enabled. If the telephone 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, change the 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.
Configuration procedure:
