More Information

Two bitmasks to disable certain phone functions in normal or in locked mode, a whitelist with numbers permitted to dial when normal outbound calls are disabled and a list with prefixes identifiying external calls can be entered via the Web Interface:

• "Phone/Protect/Fine grained Function Locking"
• "Phone/Protect/Functions to lock via PIN"
• "Phone/Protect/Numbers for Emergency Calls"
• "Phone/Protect/Prefixes for External Calls"

The same information can be entered by config upload'ing the following command line:

config change PHONE USER /lock-mask <mask> /pinlock-mask <mask> /whitelist-e164 <numbers> /external-e164 <prefixes>

Currently the following functions can be disabled:

PHONE_LOCK_DIAL_EXT 0x00000001          /// disable external call if not on whitelist
PHONE_LOCK_DIAL_INT 0x00000002          /// disable internal call if not on whitelist
PHONE_LOCK_DIAL_QUERY 0x00000004        /// disable directory search on outbound calls
PHONE_LOCK_DIAL_HISTORY 0x00000008      /// disable outbound call list access
PHONE_LOCK_RING_EXT 0x00000010          /// ignore (but log) inbound external calls
PHONE_LOCK_RING_INT 0x00000020          /// ignore (but log) inbound internal calls
PHONE_LOCK_RING_QUERY 0x00000040        /// disable directory search on inbound calls
PHONE_LOCK_RING_HISTORY 0x00000080      /// disable inbound call list access
PHONE_LOCK_CALL_COMPLETION 0x00000100   /// disable call completion
PHONE_LOCK_CALL_TRANSFER 0x00000200     /// disable call transfer
PHONE_LOCK_CALL_BROKING 0x00000400      /// disable handling of multiple calls
PHONE_LOCK_CALL_CONFERENCE 0x00000800   /// disable conference
PHONE_LOCK_CALL_DIVERSION 0x00001000    /// disable call diversion
PHONE_LOCK_FKEYS 0x00020000             /// disable function keys
PHONE_LOCK_MENU 0x00040000              /// disable any menu
PHONE_LOCK_DIRECTORY 0x00200000         /// disable directory access
PHONE_LOCK_REMOTE_CONTROL 0x01000000    /// disable remote control of phone device
PHONE_LOCK_KEY_INFO 0x20000000          /// do not display function key labels or lamps
PHONE_LOCK_CALL_INFO 0x40000000         /// do not display missed calls and active diversions
PHONE_LOCK_USAGE 0x80000000             /// restrict phone access to emergency use

The mask defined under "Fine grained Function Locking" (/lock-mask) is applied when the phone is in normal mode. The default for this mask is 0x00000000.

The mask defined under "Functions to lock via PIN" (/pinlock-mask) is applied when the phone is locked with a PIN entered in the corresponding menu. The default for this mask is 0x9fffffbf :

• outbound calls are restricted according to whitelist, an empty whitelist disables any outbound call.
• inbound calls are ignored but logged in the call list
• function keys are deactivated but show their current state (probably it would have been better to supress key state display, thus this default may be changed in a later release)
• missed calls are displayed
• aktive diversions are not displayed (this is currently not controlled by the pinlock-mask but by the pinlocked state itself, thus this cannot be changed in current version but it will be in following versions).

The whitelist is a comma separated list of numbers, including any necessary prefix. This is different to the whitelist handling of version 5 where the prefix for an external call defined in the dialling location (usually '0') was skipped before checking the further digits dialled.

The prefix list is a comma separated list of prefixes identifiying external calls, in the most simple case this list may contain only a '0'.
