Reference:Fine grained function locking

This function disables certain phone functions in normal or in locked mode, a whitelist defines which numbers are permitted to dial when normal outbound calls are disabled, a prefix list defines which calls are to be considered external calls.

Applies To

This information applies to

• IP110 V6
• IP150 V6
• IP200 V6
• IP230 V6

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>

============
  0xC0001900 <---- hide-mask

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'.

* Note: This list does not consider the PBX call Filters
