Additional Configuration Methods, Parameters, and Procedures. The Cisco IP Phone must be correctly configured before it will operate properly.
When you configure a phone, you specify parameters and values that instruct the phone how to operate in your environment. Configuring provides the phone with instructions for many aspects of its operation, including how to interact with the network and how to handle IP telephony protocols. These processes are described in detail in this manual.
These methods are optional and are available to help you configure your phones most efficiently and to provide certain configuration options that are not available through other methods. A profile file is a binary file that contains a list of tag, length, and value triplets TLVs that represent some of the configuration parameters for the Cisco IP Phone.
You can edit a text version of a profile file and then convert it to a binary file for the phone to download. In these file names, each xx is the two-digit lowercase hexadecimal representation of each integer in the phone's MAC address.
If the ff xxxxxxxxxxxx, ld xxxxxxxxxxxx, or gk xxxxxxxxxxxx profile file does not exist, the Cisco IP Phone G will try to download the profile file ffdefault. The ffdefault. The TFTP server stores the common profile file lddefault. The Cisco IP Phone G profile file name is ff xxxxxxxxxxxx , where each xx is the two-digit lowercase hexadecimal representation of each integer in the phone's MAC address.
The file name must be exactly 14 characters. For example, if the MAC address is 0. Note Profile file names begin with "ld," which is a lowercase "L" followed by a lowercase "D.

You can obtain the latest version of this file from the CCO website. Note A profile file for your phone may contain some parameters that are not described in this manual. These parameters are reserved for future use or are configured with factory default settings and should not be changed. Before you can create a new binary profile file, you will need the cfgfmt.
The cfgfmt. This file specifies the type and size of each parameter. It is recommended that you use the ptag. You can also obtain them from the CCO website. For a description of profile file parameters, see the "Configuration Parameters" section.

If you do not set up a password, you will be able to view information in these areas, but you will not be able to change parameters, and Apply will not be available. For more information, see the "Device Information" section. For more information, see the "Network Configuration" section. For more information, see the "Network Statistics" section.
For more information, see the "Device Logs" section. For more information, see the "Network Parameters" section. For more information, see the "Tone Parameters" section. For more information, see the "Audio Parameters" section. If you have set up a password with the UIPassword parameter in the profile file, enter the password in the UIPassword field, and then click Apply.

For more information about using Nprintf and preserv. Bits 0 - 7—Interval between each call-waiting tone. The range is 0 to The setting 0 specifies the factory default.
Any other number specifies the interval in 0. The default setting is 0x64, 10 seconds. Bits 28 - 29—First repeat interval for the Volume and Navigation buttons. That is, the button takes effect the first time a user presses and holds down the button for the interval specified. The default value is 0. Bits 30 - 31—Subsequent repeat interval for the Volume and Navigation buttons. For example, the volume increases or decreases when a user continues to hold down the Volume button for the interval specified.
Three comma-separated integers, a , b , c , where:. Comma-separated string of nine integers, a through i. See the DialTone parameter for a description of these integers.
