the call, the call is rejected.
12.2.1.2 Locking Extension
To lock an extension with a common authorization code, do the
following:
1. Dial *73* authorization code #.
Wait for a verification tone.
2. When you hear a verification tone and the lock icon appears in the
display, the extension is locked.
If you wish to make a call from a locked phone, different service profiles
will be used depending on whether you enter an authorization code or
not.
• When the telephone is locked, you have to dial *72* in order to
acquire a higher level of service profile. If you do not enter an
authorization code, the default service profile will be used.
• If you enter a valid authorization code, the service profile associ-
ated with the authorization code will be used.
12.2.1.3 Unlocking an Extension
To unlock an extension with a common authorization code, do the
following:
• Dial #73* authorization code #.
When you hear a verification tone and the lock icon disappears
from the display, the extension is unlocked.
Note: If the telephone is unlocked, you do not have to dial any authori-
zation code.
12.2.2 Individual Authorization Code
If your extension has an individual authorization code associated with it,
you can lock your own extension to a service profile when, for example,
you are out of the office. Temporarily, you can call from another tele-
phone and get the same service profile as for your own extension.
The individual authorization code provides three different functions:
• Locking and unlocking of an extension. A locked extension uses a
low service profile.
