Additional Configuration Methods and Parameters
The Cisco Unified 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.
In general, configuring the Cisco Unified IP Phone 7905G and 7912G can be accomplished through Cisco Unified CallManager and through the network configuration options on a phone. These processes are described in detail in this manual.
This appendix describes the following additional methods for configuring the Cisco Unified IP Phone 7905G and 7912G. 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.
•
Through a profile file—A profile file contains various parameters and values for phone and network settings. This file is stored on a Trivial File Transfer Protocol (TFTP) server and is downloaded to the phone.
•Through the phone's web page—Each phone has a web page from which you can view and update many parameter values.
This section includes the following topics:
•TFTP Configuring
•Web Page Configuring
•Configuration Parameters
TFTP Configuring
You can configure many parameters on the Cisco Unified IP Phone 7905G and 7912G using a profile file stored on the TFTP server. 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 Unified 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.
TFTP configuration works as follows:
1. A Cisco Unified IP Phone will try to download a phone-specific profile file from the TFTP server.
2. If the phone-specific profile file does not exist, the phone will try to download a common, or default, profile file.

About Profile Files
A profile file is a binary-format file that is stored on the TFTP server. There are two types of profile files:
•Phone-specific profile files— Used to configure a particular Cisco Unified IP Phone
•Common profile files—Used to simultaneously configure multiple phones of the same model with the same information
Table A-1 explains how these profile files are named.

|
•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 the Cisco Unified IP Phone 7905G and 7912G, the profile file names begin with a lowercase "L" followed by a lowercase "D"
•For example, if the MAC address is 0.1.45.2.10.20, the file name is ld00012d020a14

|
You can edit a profile file in text format on the TFTP server and then convert it to the binary format required by the phone. See the "Creating or Updating a Profile File" section for more information.
Configuration parameters are entered in the format "Parameter:value." For example, the following entry specifies that the password for accessing a phone's web page or Network Configuration screen is 12345: UIPassword:12345. See the "Configuration Parameters" section for more information about parameters and values.
Use the file example_uprofile.txt as a template for creating the text version of your Cisco Unified IP Phone profile files. You can obtain the latest version of this file from the CCO website. It is included with the SCCP Software Package Zip file.
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.

Creating or Updating a Profile File
Use the file example_uprofile.txt or an existing text profile file as a template for creating a text version of a Cisco Unified IP Phone profile file.
Profile File Conventions
A text profile file must conform to the following conventions:
•The characters #txt must appear at the beginning of the first line of the file so that the formatting tool, cfgfmt.exe, will treat the file as a text file
•A pound sign (#) at the beginning of a line indicates a comment
•Parameter/value pairs are entered in the form parameter:value, where parameter is the exact name of the parameter and value is a valid value
•Each parameter/value pair must appear on a its own line
•All parameter/value pairs are optional, but the Cisco Unified IP Phone 7905G might not function properly if some values are missing.
•A parameter value is one of the following types:
–Alphanumeric string
–Numeric digit string
–Array of short integers
–IP address (for example, 192.168.2.170)
–Extended IP address—IP address with port (for example, 192.168.2.170.9001)
–Boolean (1 or 0)
–Bitmap—unsigned hexadecimal integer (for specifying bits in 32-bit integer)
–Integer (32-bit integer)
Editing a Profile File and Converting it to Binary Format
Before you can create a new binary profile file, you will need the cfgfmt.exe tool, which converts a text profile file to binary format.
The cfgfmt.exe tool requires a parameter tag file named ptag.dat. This file specifies the type and size of each parameter.
The cfgfmt.exe tool and the ptag.dat are bundled with the Cisco Unified IP Phone software. You can also obtain them from the CCO website. They are included with the SCCP Software Package Zip file.
To create or update a profile file, follow these steps:
Procedure
Step 1 Use a text editor to open the text version of the profile file on the TFTP server.
Step 2 Make changes as needed to the profile file, and save it.
For a description of profile file parameters, see the "Configuration Parameters" section.
Step 3 Open a command window and type the following command to generate the binary profile file from the text file:
cfgfmt [-tpTagFile] input-text-file output-binary-file
where:
•pTagFile is an optional path to a folder containing the ptag.dat file. Specify this path if the ptag.dat file is not in the directory from which you are running the cfgfmt.exe tool.
•input-text-file is the name of the text version of the profile file.
•output-binary-file is the name of the binary file that the Cisco Unified IP Phone uses as the TFTP configuration profile file. See the "About Profile Files" section for profile file name requirements.
Step 4 Put the binary file in these locations:
•The root directory on the TFTP server (C:\Program Files\cisco\tftppath)
•The network locale directories on the TFTP server for each language that is supported by Cisco Unified CallManager.
The default network locale directory on the TFTP server is C:\Program Files\ cisco\tftppath\United_States.
Web Page Configuring
You can display and configure device and network information for a Cisco Unified IP Phone by accessing the phone's web page. You can access the web page using any graphically capable web browser.
Note It is recommended that you take care to prevent unauthorized access to a phone's web page. It is also recommended that you increase security by setting a password using the UIPassword parameter in the phone's profile file. For more information about this parameter, see Table A-8.
