# Site Alerting (Standortalarmierung)

**Site Alerting** (German: *Standortalarmierung*) is a high-priority telephony feature deployed across the [[universitat-greifswald]] to facilitate emergency notifications within specific buildings.

## Functionality and Behavior
The system allows a user to send an emergency information message to all other telephone devices located within the same building. To ensure the message is seen during critical situations, the alert overrides several common telephone settings:
- **Do Not Disturb (DND)**: The alert is displayed even if DND is active.
- **Silence Mode**: The alert bypasses silence settings.
- **Call Forwarding**: The alert is displayed on the device regardless of active forwarding.

### Critical Limitations
- **No External Forwarding**: If a phone has call forwarding active, the site alert is **not** forwarded to the external target; it only appears on the physical devices within the building.
- **Not an Emergency Service**: This function is for internal building notification only. It is **not** a replacement for official emergency calls to **112** (Medical/Fire) or **110** (Police).

## Technical Implementation
The [[universitatsrechenzentrum-urz]] manages the deployment of this service automatically on a building-by-building basis.

### Hardware Interface
On supported hardware (such as **SNOM** devices), the alerting function is mapped to a specific physical key:
- **Key**: Function Key 6.
- **Position**: Top right of the 12-key block.

## Related Services
This feature is part of the broader telephony infrastructure managed via the [[telefonportal]].
