Prerequisites
Installation Strategy
Choose one of the following installation strategies:
•Download, then customize. Download the firmware image and configuration files to your TFTP server. Connect each phone to power, causing it to automatically download the image and default files. Configure each phone individually as needed.
•Customize, then download. Download the firmware image and configuration files to your TFTP server. Open the configuration files and customize parameters for all the phones at once. Save the customized file to the TFTP server. Connect each phone to power, causing it to automatically download the image and customized files.
Network Functionality
Ensure that your network meets the following requirements:
•A working IP network is established and configured for MGCP.
For information on configuring IP, refer to the Cisco IOS IP Configuration Guide.
http://www.cisco.com/univercd/cc/td/doc/product/software/ios123/123cgcr/ip_vcg.htm
•VoIP is configured on your Cisco routers.
For information on configuring VoIP, refer to the Cisco IOS Voice Configuration Library.
http://www.cisco.com/univercd/cc/td/doc/product/software/ios123/123cgcr/vcl.htm
•A TFTP server is configured on your network.
When the phone initializes, it requests the following from the TFTP server:
–Latest firmware image
–Dual-boot file (OS79XX.TXT)
–Phone-specific MAC-address configuration file
–Default configuration file
–Ring-list file
–Dial-plan file
For the information about configuring your TFTP server, refer to your operating-system documentation.
•A DHCP server is configured on your network.
The phone uses DHCP to obtain IP addresses. Configuration options are as follows:
–dhcp option #1 (IP subnet mask)
–dhcp option #3 (default IP gateway)
–dhcp option #6 (DNS server IP address)
–dhcp option #15 (domain name)
–dhcp option #50 (IP address)
–dhcp option #66 (TFTP server IP address)
If you do not configure DHCP options on the DHCP server, you must manually configure them on the phone. For information on configuring a DHCP server, refer to your operating-system documentation.
•A proxy server is active and configured to receive and forward messages.
Note Refer to the Cisco 7940 and 7960 IP Phones Firmware Upgrade Matrix for additional prerequisites.
Overview of the Initialization Process
The initialization process for the Cisco MGCP IP phone establishes network connectivity and makes the phone operational in your MGCP network. After you connect your phone to the network and to a power supply, the phone begins initialization, during which the following occurs:
1. The phone loads the firmware image.
The phone has nonvolatile flash memory that contains permanent factory information about the phone and, eventually, firmware images and user-defined preferences. During initialization, the phone runs a bootstrap loader that loads the firmware image.
2. The phone learns its VLAN membership.
If the phone is connected to a Cisco Catalyst switch, the switch notifies the phone of the voice VLAN defined on the switch. The phone needs to know its VLAN membership before it can send a DHCP request for its IP settings (if using DHCP).
3. The phone acquires its IP address.
If the phone uses DHCP to obtain IP settings, it queries the DHCP server. Otherwise, it uses IP settings that are stored in flash memory.
4. The phone contacts the TFTP server and downloads the following files (or uses settings that are stored in its flash memory):
•SEP<macaddress>.cnf.xml—Creates the filename SEP<macaddress>.cnf.xml on the TFTP server into which you can place one of the following:
<device>
<loadInformation>P0M3-07-3-00</loadInformation>
</device>
The phone then checks the load information and either upgrades the phone firmware in FLASH memory to the version stated in the <LoadInformation> tag using the TFTP loader in the Universal Application Loader, or, if the version matches, exits the Universal Application Loader and executes the firmware already loaded in FLASH memory.
•<firmware-version>.loads—If the version matches, enables the phone to exit the Universal Application Loader and executes the firmware already loaded in FLASH memory, as defined in SEP<macaddress>.cnf.xml.
•OS79XX.TXT—Enables the phone to initialize and automatically determine the network in which it is being installed.
Note The use of dual boot file OS79XX.TXT is deprecated in favor of individual XML configuration files for the phone using their SEP<macaddress>.cnf.xml style names. This allows Cisco CallManager and MGCP-based configurations to share a common TFTP server, as the XML configuration is phone-specific and allows indivbidual phones to be switched between SIP, SCCP, or MGCP images.
•MGCPDefault.cnf—Contains parameters intended for all phones. For information on customizing the file, see the "How to Customize the Default Configuration File" section.
•MGC<mac-addr>.cnf—Contains parameters specific to a phone. Use this file as a template from which to create a file for each phone. Insert the MAC address of the phone in the filename.
•RINGLIST.DAT—Lists audio files that are the custom-ring-type options for the phones. The files must be in the root directory of the TFTP server.
•dialplan.xml—Contains the North American sample dial plan. You can push the file down to the phones with a notify (NTFY) message with a check-sync Event header.
Note Refer to the Cisco 7940 and 7960 IP Phones Firmware Upgrade Matrix for additional information.
5. The phone verifies the firmware version.
If the phone determines that the image defined in a configuration file differs from the image that it has stored in flash memory, it performs a firmware upgrade. During upgrade, the phone downloads the firmware image from the TFTP server, programs the image into flash memory, and reboots.
Note Upon startup, the phone attempts to download both configuration files. If neither file exists, a TFTP timeout occurs after approximately 9 seconds per file. If the files exist, they are parsed and processed. These files are not required for the phone to initialize; however, it takes longer (approximately 20 seconds) for the phone to boot because it is waiting for the timeout on the TFTP server. Both configuration files can use the same values or they can contain empty values. If the files contain empty values, the phone boots using default values for some of the parameters.
Note Values in the phone-specific configuration file take precedence over those in the default configuration file because the phone-specific file is processed last.
Information About Configuration Files
Configuration files reside in a TFTP server subdirectory (you specify the location of this subdirectory with the tftp_cfg_dir parameter). For more information, refer to the Cisco 7940 and 7960 IP Phones Firmware Upgrade Matrix.
Note Be sure to customize configuration files before you power up the phone. When powered up, the phone automatically loads parameters stored in flash memory and then requests configuration files from the TFTP server.
When modifying parameters, remember the following:
•Parameters in the configuration file override those stored in the phone's flash memory.
•Locally changed parameters are used until the next reboot.
•The name of each phone-specific configuration file is unique and is based on the MAC address of the phone.
The format of the filename must be MGCPXXXXYYYYZZZZ.cnf, where XXXXYYYYZZZZ is the MAC address of the phone. The MAC address must be in uppercase; the .cnf extension must be in lowercase (for example, MGCP00503EFFD842.cnf).
Note You can find the MAC address of a phone on the middle sticker adhered to the base of the phone. You can also view it on the Network Configuration menu.
•Each line in a configuration file must use the following format and must adhere to the following rules:
variable-name : value ; optional comments
–Associate only one value with one variable.
–Separate variable names and values with colons.
–Set only one variable per line.
–Indicate the end of a line with <lf> or <cr><lf>.
–Put the variable and value on the same line, and do not break the line.
–You can include white space before or after a variable or value. You can include any character within them. However, if white spaces are needed within the value, you must enclose the value in single or double quotes. If the value is enclosed in quotes, the end quote must be the same as the start quote.
–You can include comments after the value. Use the semicolon (;) and pound (#) delimiters to distinguish the comments.
–You can include comment lines.
–You can include blank lines.
You can use any case for variables; they are not case sensitive.
How to Customize the Default Configuration File
You have the following installation choices:
•Download, then customize. Download the default configuration file to your TFTP server, and then plug each phone into power and the network. The phones automatically download the default configuration file from the TFTP server. You can then customize parameters if required.
•Customize, then download. Download the default configuration file to your TFTP server, open the file, customize parameters for all the phones at once, save the customized file, and then plug the phones into power and the network. The phones automatically download the customized file from the TFTP server.
This section describes how to customize, then download. Maintaining parameters—such as whether phones must register with a proxy server and the codec that phones must use when initiating a call—in the default configuration file allows you to perform global changes, such as upgrading the image version, without having to customize the phone-specific configuration file for each phone.
Note For a complete alphabetical list of configurable parameters, see Appendix B, "Configurable Parameters for the MGCP IP Phone."

How to Customize a Phone-Specific Configuration File
You can define parameters that are specific to a particular phone, such as the lines configured on a phone and the defined users for those lines, in a phone-specific configuration file.
Note•If you configure a line to use an e-mail address, that line can be called only by using the e-mail address. Similarly, if you configure a line to use a number, that line can be called only by using the number. Each line can have a different proxy configured.
•Define the dial_template parameter in the default configuration file for maintenance and control purposes. Define the parameter in a phone-specific configuration file only if that phone needs to use a different dial plan than the one being used by the other phones in the same system.
•For a complete alphabetical list of configurable parameters, see Appendix B, "Configurable Parameters for the MGCP IP Phone."
Procedure
Step 1 Obtain the phone-specific configuration file as follows:
a. Go to the Cisco.com MGCP IP 7940/7960 phone software-download site at http://www.cisco.com/cgi-bin/tablebuild.pl/mgcp-ip-phone7960.
b. Download the MGCP<mac-addr>.cnf file to the root directory of your TFTP server or to a subdirectory in which all phone-specific configuration files are stored.
Step 2 Do the following for each phone that you plan to install:
a. Using an ASCII editor, create and open an MGCP<mac-addr>.cnf file for the phone.
b. Modify parameters as needed.
c. Save the file to the root directory of your TFTP server or to a subdirectory that contains all the phone-specific configuration files. Name the file MGCP<mac-addr>.cnf. The MAC address must be in uppercase and the extension, cnf, must be in lowercase (for example, MGCP00503EFFD842.cnf).

How to Customize the Configuration from the Phone Menu
After the phone has been connected to power and initialized and the configuration files have been downloaded, you can modify your configuration using the phone menu.
This section contains the following procedures:
•Unlocking and Locking the Phone
•Setting and Restoring Network Parameters
•Setting and Restoring Phone-Specific Parameters
•Setting End-User Call Preferences
Tip•To select a parameter, press the down arrow to scroll to and highlight the parameter, or press the number that represents the parameter (located to the left of the parameter on the LCD).
•During configuration, use * for dots (periods) or press the "." soft key when available on the LCD.
•During configuration:
–To enter a number, press the Number soft key. To enter a name, press the Alpha soft key.
–To enter a new value, use the buttons on the dial pad.
If entering letters, use the numbers on the dial pad that are associated with a particular letter. For example, the 2 key has the letters A, B, and C. For a lowercase a, press the 2 key once. To scroll through the available letters and numbers, press the key repeatedly.
–To delete any mistakes, press the << soft key.
–To cancel all changes and exit a menu during configuration, press Cancel.
•After editing a parameter, press the Validate soft key to save the value that you have entered and exit the Edit panel.
Modifying your configuration using the phone menus requires that you unlock and relock the phone. A padlock icon in the upper-right corner of your LCD displays on the phone when the phone is locked. By default, the phone is locked.
Note If the Network Configuration or MGCP Configuration menu is displayed, the lock icon in the upper-right corner of your LCD changes to an unlocked state. If you are located elsewhere in the Cisco IP 7960G/7940G phone menus, the next time you access the Network Configuration or MGCP Configuration menus, the unlocked icon displays, and you can modify the network and MGCP configuration settings.
Unlocking and Locking the Phone
You must unlock and relock the phone to modify a configuration using the phone menus. Similarly, phone users must unlock and relock the phone to modify end-user parameters.
A padlock icon in the upper-right corner of your LCD displays on the phone when the phone is locked. By default, the phone is locked.
Prerequisites
•Set the phone password with the phone_password parameter in the phone-specific configuration file.
Procedure
Step 1 To unlock the phone, do the following:
a. Press Settings > Unlock Config. The password prompt displays.
b. Enter a phone password. The phone unlocks, and the unlock icon displays on the LCD.
Note The Unlock Config menu choice changes to Lock Config and the configuration remains unlocked while you work within it. When you exit the configuration menu, the configuration automatically relocks.
Step 2 To relock the phone, select Lock Config or Exit.
Setting and Restoring Network Parameters
You can modify network parameters using the phone menus.
Note•TFTPServer may be a required parameter, depending on how you intend for the phone to locate the TFTP server from which it downloads its configuration file. You can provide the TFTP server IP address in either of two ways:
–Provide it to the DHCP server. (For information, see the "Prerequisites" section.) Using normal Cisco Discovery Protocol (CDP) processes, the phone locates the DHCP server upon connection to the network; the server in turn provides the TFTP server address.
–Provide it directly to the phone by means of the TFTPServer parameter as described in this procedure. If you use this method, first select DHCP Enabled > No.
•For a complete alphabetical list of configurable parameters, see Appendix B, "Configurable Parameters for the MGCP IP Phone."
Procedure
Step 1 Unlock the phone (see the "Unlocking and Locking the Phone" section).
Step 2 Select Settings > Network Configuration. The Network Configuration menu displays.
Step 3 To set a parameter, select it and set it as desired.
Step 4 To restore all parameters to their defaults, select Erase Config > Yes.
Note If DHCP is disabled on a phone, restoring default phone settings reenables DHCP.
Step 5 Select Save. The phone programs the new information into flash memory and resets.
Step 6 Relock the phone.
Setting and Restoring Phone-Specific Parameters
Phone users can modify the phone-specific configuration settings using the phone menus.
Note•Parameters defined in the default configuration file override those specified in the phone-specific configuration file.
•If a phone-specific configuration file exists, the phone uses parameters entered locally until the next reboot.
•If you do not configure the phone using a TFTP server, you must configure the phone locally.
•To configure the preferred codec and out-of-band DTMF parameters, press Change until the option displays and then press Save.
•If your system has been set up to have the phones retrieve the configuration file from a TFTP server, you must use the server's configuration file to change the parameter value to a null value " " or to "UNPROVISIONED." The phone uses the setting for that variable that it has stored in flash memory.
•If the telnet_level parameter is set to allow privileged commands to be executed, the entire MGCP configuration can be erased. Use the erase_protflash command so that the phone can retrieve its configuration files.
Prerequisites
•Define the line parameters (those identified as linex) on the phone. If you configure a line to use an e-mail address, that line can be called only by using an e-mail address. Similarly, if you configure a line to use a number, that line can be called only by using the number.
Procedure
Step 1 Unlock the phone (see the "Unlocking and Locking the Phone" section).
Step 2 Select Settings > MGCP Configuration. The MGCP Configuration menu displays.
Step 3 To set a required parameter, select it and set it as desired. The following are required parameters that you must set now if you did not set them in the default configuration file as described in the "How to Customize the Default Configuration File" section:
•CA IP address
•Phone input port
•Phone output port
Step 4 To set an additional parameter, select it and set it as desired.
Step 5 To restore a parameter to its default, do the following:
a. One at a time, highlight the parameter whose setting you want to erase, and then select Edit followed by <<.
b. Select Validate > Exit.
c. If necessary, select Back to exit the menu.
Step 6 Select Save. The phone programs the new information into flash memory and resets.
Step 7 Relock the phone.
Setting End-User Call Preferences
End users can modify call preferences from their own phones, according to how you set the associated parameters.
Prerequisites
•Set configuration variables for call preferences as follows (see the "How to Customize a Phone-Specific Configuration File" section):
–To enable end users to modify a preference, set to 0 or 1.
–To prohibit end users from modifying a preference, set to 2 or 3.
Procedure
Step 1 Unlock the phone (see the "Unlocking and Locking the Phone" section).
Step 2 On the IP phone, select Settings > Call Preferences.
Step 3 Set any of the preferences to the desired setting.
Step 4 Select Save. The phone programs the new information into flash memory and resets.
Step 5 Relock the phone.
How to Set the Date and Time
You can set date, time, and daylight savings time (DST) parameters. The current date and time is supported on the Cisco IP 7960G/7940G phone using Simple Network Time Protocol (SNTP) and is displayed on the LCD. DST and time-zone settings are also supported.
International time-zone abbreviations are supported and must be in all capital letters.
Note We recommend that you set date- and time-related parameters in the default file for all phones. Alternatively, you can set the time-zone parameter manually on the phone or in the phone-specific configuration files.
Prerequisites
•Determine the type of DST that you want to configure:
–Absolute DST (for example, starts on April 1 and ends on October 1)
–Relative DST (for example, starts on the first Sunday in April and ends on the last Sunday of October)
Review the list of common and absolute DST parameters from Appendix B, "Configurable Parameters for the MGCP IP Phone."
•Review the information on SNTP in Table 3-1. SNTP parameters specify how the phone obtains the current time from an SNTP server.
•Determine your time zone from Table 3-2.
Procedure
Step 1 Using an ASCII text editor such as vi, open the MGCPDefault.cnf file.
Step 2 Modify the following SNTP parameters as needed:
•sntp_mode
•sntp_server
•time_zone
Step 3 Modify the following common DST parameters as needed:
•dst_offset
•dst_auto_adjust
•dst_start_month
•dst_stop_month
•dst_start_time
•dst_stop_time
Step 4 Do one of the following:
•Modify the following absolute DST parameters as needed:
–dst_start_day
–dst_stop_day
•Modify the following relative DST parameters as needed:
–dst_start_day_of_week
–dst_start_week_of_month
–dst_stop_day_of_week
–dst_stop_week_of_month
Step 5 Save the file to the root directory of your TFTP server.
Note To adjust the phone display to European Day-Month-Year format, add the following entry to the MGCPDefault.cnf file: date_format:D/M/Y.
Table 3-1 describes the effects on SNTP mode when the SNTP server is null (not assigned an IP address) or when it is assigned a valid IP address.

How to Verify Initialization
The initialization process establishes network connectivity and makes the phone operational in your IP network.
Procedure
Step 1 After the phone has power connected to it, ensure that the phone cycles through the following steps.The following flash on and off in sequence: Headset button, Mute button, and Speaker button.
Step 2 The Cisco Systems, Inc. copyright appears on the LCD.
Step 3 The following messages appear:
•Configuring VLAN—The phone configures the Ethernet connection.
•Configuring IP—The phone contacts the DHCP server to obtain network parameters and the IP address of the TFTP server.
•Requesting Configuration—The phone contacts the TFTP server to request its configuration files and compares firmware images.
•Upgrading Software—The phone displays this message only if it determines that an image upgrade is required. After upgrading the image, the phone automatically reboots to run the new image.
Step 4 The main LCD displays the following:
•Primary directory number
•Soft keys
If the phone successfully cycles through these steps, it has started up properly.
Where to Go Next
•See Chapter 4, "Managing Cisco MGCP IP Phones," for information on upgrading firmware and performing other management tasks.
•See Chapter 5, "Monitoring Cisco MGCP IP Phones," for information on debugging and on viewing network statistics.
