5.8.13 Disabling the HOLD Key
Note: Support pending.
The network administrator can disable hard keys and softkeys on phones. The feature is
motivated by the requirement on the part of some enterprises to control settings remotely to
comply with company policy.
 To disable the HOLD key:
• Use the table as reference.
Table 5-44: Disabling the HOLD Key
Parameter Description
system/disable_hold_button

HOLD key is used to place a call on hold, or to resume
a held call.
Besides the HOLD key, other hard keys that can be disabled include speaker, headset,
voicemail, REDIAL, CONTACTS, MENU, TRANSFER, VOL and mute.
For more information, see Section 6.3.
5.8.14 Configuring Onhook Disconnect when Held

hook) when the last remaining call is disconnected, or not.

 0 Disable (default) - If the receiver is placed on-
hook after a call is put on hold, the call is put on
speaker rather; it isn't disconnected.
 1 Enable - If the receiver is placed on-hook after a
call is put on hold, the call is disconnected.
