Select the method for the location check.
SNMP ID: 2.11.31.6
Telnet path: Setup/Config/Anti-Theft-Protection
Possible values:
- Basic call: 'Self call' for a check via ISDN by means of a return call.
- Facility: Call forwarding check via ISDN by requesting the call number from the exchange. No call-back is necessary in this case.
- GPS: GPS verification for a check on the geographical coordinates.
Note: For a location check by GPS an appropriate GPS antenna must be connected to the AUX connector on the device. Additionally, a SIM card for mobile telephone operation has to be inserted and the device must be logged on to a mobile phone network. For ISDN location verification to function, the device must be reachable from the public ISDN telephone network. The device needs two free B channels for the duration of the check. If just one channel is free, e.g. one channel at a point-to-multipoint connection with two B channels is being used for a telephone call, then the device cannot make a call to itself via ISDN.
