Valid for N670 / N870 / N870E but not supported by N610. Software 2.42 or higher is needed.

The Alarm, Messaging and Location (AML) feature contains the following features.

  1. Alarm: The user can start an Alarm from the DECT handset
  2. Messaging: Messages from an Alarm server (Other server/platform) are send to the DECT handsets
  3. Location: An location server can request from the DECT handset the DECT and/or BLE received signal strength and with this calculate the expected location of the handset

The user would have the possibility to trigger an alarm via the DECT handset. Of course in these environments, handsets are just one way to trigger an alarm. External buttons or sensors often are also available.

Specialized DECT handsets can automatically generate alarm calls to the configured alarm destination. The alerted party recognizes the alerting party from the caller's phone number for example. The following possibilities are available to start alarm calls.
