8.1 Telephone Lock

Activating:

H*33* Z (user PIN) #

Deactivating:

H#33* Z (user PIN) #

You can lock your telephone as a safeguard against unauthorised use. Then only

those features and functions of your telephone can be accessed that are preset in

the OpenCom 100 / Aastra 800 Configurator for the “Guests” user group. You

must enter your user PIN to activate the telephone lock (see Changing the User PIN

on page 31).

Note: National emergency numbers can still be dialled al-

though the telephone lock is activated, providing they have

been defined in your user group’s special list in the

OpenCom 100 / Aastra 800. Ask your system administrator

for these numbers.

You cannot activate/deactivate the telephone lock on a SIP terminal using the

code-number procedure described here. You can, however, operate the feature

with the OpenCTI 50 additional programme. To do so, the system administrator

has to authorise you to use this programme. For more information, please refer to

the online help of the OpenCom 100 / Aastra 800.
