IP Phone Release Notes 2.4
Per-Parameter Locking from the Configuration File
The IP Phones now allow you to lock individual configuration parameters to prevent an end user
from changing the configuration on the phone. This feature allows service providers to prevent
the end-user from changing the values of specific parameters that would affect the service they
provide.
An Administrator can lock parameters on the phone by placing an exclamation mark (
!
) before
the parameter in the configuration file. For example,
!
admin password: 22222
!
emergency dial plan: 911|999
You can lock parameters on the phone using the configuration files only. Once the parameters
are locked, they cannot be changed at all during the phones run-time. The parameters appear as
read-only when accessing the Aastra Web UI and the IP Phone UI. In the Aastra Web UI, they
appear grayed out. In the IP Phone UI the ability to change the parameters is removed. In
addition, when parameters are locked, they cannot be changed via XML.
Limitations
• A User possessing the Administrator password can bypass the locking of configuration
server details by defaulting the phone.
• Parameters cannot be locked using XML.
• Configuration files that include locked parameters are not backwards compatible
Configuration Features
Notes:
1. The “parameter locking” feature applies to Release 2.4 and up. Any
phones that have a previous release loaded on the phone will not be able
to use the locking functionality in the configuration file.
2.
Any parameter duplicated in the mac.cfg from the aastra.cfg is
overwritten by the locking status and the value of the parameter found in
the mac.cfg file.
