Unlocking and Locking Options

Configuration options that can be changed from a phone are locked by default to prevent users from making changes that could affect the operation of a phone. You must unlock these options before you can change them.

When options are inaccessible for modification, a locked padlock icon appears on the configuration menus. When options are unlocked and accessible for modification, an unlocked padlock icon appears on these menus, as shown next.

To unlock or lock options, press **#. This action either locks or unlocks the options, depending on the previous state.

After you have made your changes, you must lock the options.

---

Caution Do not press **# to unlock options and then immediately press **# again to lock options. The phone will interpret this sequence as **#**, which will reset the phone. To lock options after unlocking them, wait at least 10 seconds before you press **# again.

Editing the Values of an Option Setting

When you edit the value of an option setting, follow these guidelines:

•Use the keys on the keypad to enter numbers and letters.

•To enter letters using the keypad, use a corresponding number key. Press the key one or more times to display a particular letter. For example, press the 2 key once for "a," twice quickly for "b," and three times quickly for "c." After you pause, the cursor automatically advances to allow you to enter the next letter.

•To enter a period (for example, in an IP address), press the . (period) softkey or press * on the keypad.

•Press the << softkey if you make a mistake. This softkey deletes the character to the left of the cursor.

•Press the Cancel softkey before pressing the Save softkey to discard any changes that you have made.

Network Configuration

The Network Configuration menu contains the Load Server option, which is used to optimize firmware upgrades. Table 4-12 describes this option.

Table 4-12 Network Configuration Menu Options 

Option	Description	To Change
Load Server	Used to optimize installation time for phone firmware upgrades and offload the WAN by storing images locally, negating the need to traverse the WAN link for each phone's upgrade. You can set the Load Server to another TFTP server IP address or name (other than the TFTP Server 1 or TFTP Server 2) from which the phone firmware can be retrieved for phone upgrades. When the Load Server option is set, the phone contacts the designated server for the firmware upgrade. Note The Load Server option allows you to specify an alternate TFTP server for phone upgrades only. The phone continues to use TFTP Server 1 or TFTP Server 2 to obtain configuration files. The Load Server option does not provide management of the process and of the files, such as file transfer, compression, deletion, and so on.	Use Cisco Unified CallManager Administration to modify.
