This chapter explains the Cisco SIP IP phone initialization and the process that you should follow to install and connect the Cisco SIP IP phone.
This chapter provides the following major sections:
The initialization process of the Cisco SIP IP phone is responsible for establishing network connectivity and for making the phone operational in your IP network.
Once you connect your phone to the network and to an electrical supply, the phone begins its initialization process.
During the initialization process, the following events take place:
1. The stored image is loaded.
The Cisco SIP IP phone has non-volatile Flash memory in which it stores the firmware images, user-defined preferences, and permanent factory information about the phone.
During initialization, the phone runs a bootstrap loader that loads and executes the phone image stored in Flash memory.
If the Cisco SIP IP phone is connected to a 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 proceed with the DHCP request for its IP settings (if using DHCP).
If the Cisco SIP IP phone is using DHCP to obtain the IP settings, the phone queries the DHCP server. If the phone is not using DHCP, then the phone will use IP settings that are stored in Flash memory.
4. The TFTP server is contacted.
On the TFTP server is the latest Cisco SIP IP phone firmware image and the dual boot file (OS79XX.TXT) that enables the phone to automatically determine and initialize for the VoIP environment in which it is being installed.
If the phone is using the TFTP server to obtain its SIP parameters, there should also be a configuration file or files on the TFTP server that the phone will request and download. In the configuration file or files, SIP parameters that are required by the phone to operate in a SIP VoIP environment are defined. If the phone is not obtaining its SIP parameters via the TFTP server, the phone will use SIP settings that are stored in Flash memory.
5. The firmware version is verified.
If the phone is obtaining its SIP parameters via a TFTP server, the configuration files are requested. If the phone determines that the image defined in a configuration file differs from the image it has stored in Flash memory, it performs a firmware upgrade.
When performing a firmware upgrade, the phone downloads the firmware image from the TFTP server, programs the image into Flash memory, and reboots.
This section contains information on how to install Cisco SIP IP phones in your IP network. Before getting started, read over the information in this section carefully.
To successfully install the Cisco SIP IP phone, you must complete the following tasks:
1. Download the required files from CCO to the TFTP server as described in the the "Downloading Files to Your TFTP Server" section.
2. If you are configuring SIP parameters via a TFTP server, create and store the configuration files as described in the "Configuring SIP Parameters via a TFTP Server" section.
3. If you are using DCHP to configure the phones' network settings, configure the required network parameters on your DHCP server as described in the "Configuring Network Parameters via a DHCP Server" section.
4. Connect the phone to the network and to a power supply as described in the "Connecting the Phone" section.
5. If you are not using DHCP to configure network parameters, manually configure the required network parameters as described in the "Manually Configuring the Network Parameters" section.
6. If you are not configuring the SIP parameters via a TFTP server, manually configure the required parameters as described in the "Manually Configuring the SIP Parameters" section.
Before installing the Cisco SIP IP phones, copy the following files from CCO to the root directory of your TFTP server.

Note This section describes how to configure the basic SIP parameters that are required for the phone to operate in a SIP VoIP environment. For a complete list of the SIP parameters that you can configure, see the "Modifyin g the Phone's SIP Settings" section. |
The SIP parameters are those parameters that a Cisco SIP IP phone needs to operate in a SIP VoIP environment. You can configure SIP parameters via a TFTP server or you can manually configure the parameters on a phone-by-phone basis after connecting the phones.
When the phone initializes, it loads the parameters stored in Flash memory. After loading the parameters stored in Flash memory, the phone requests the default configuration file from the TFTP server. If the default configuration file has been configured and stored in the root directory of the TFTP server, the phone reads the parameters defined in the file, and stores those parameters that differ in Flash memory. The phone then requests its phone-specific configuration file. If the phone-specific configuration file has been configured and placed in the root directory of the TFTP server, the phone reads the parameters defined in the file and stores those parameters that differ in Flash memory.
Therefore, when configuring SIP parameters, remember the following:
If you are configuring SIP parameters via a TFTP server, you must use configuration files.
There are two configuration files that you can use to define the SIP parameters; the default configuration file and the phone-specific configuration file. These configuration files must be stored in the root directory of your TFTP server.
You can use the default configuration file to define values for SIP parameters that are common to all phones. You can use the phone-specific configuration file to define parameters that are specific to a phone. Phone-specific parameters should only be defined via a phone-specific configuration file or manually configured. Phone-specific parameters should not be defined in the default configuration file.
When modifying the default configuration file and creating the phone-specific configuration files, adhere to the following guidelines and requirements:
The format of the file name must be "SIPXXXXYYYYZZZZ.cnf" where XXXXYYYYZZZZ is the MAC address of the phone. The MAC address must be in uppercase and the extension, cnf, must be in lower case (for example, SIP00503EFFD842.cnf).
|
Note The MAC address of a phone is identified on the middle sticker adhered to the base of the phone and can also be viewed on the Network Configuration menu. |
In the default configuration file (SIPDefault.cnf), we recommend that you define the SIP parameters that will be common to all of your phones such as the image_version parameter and call environment parameters (for example, will the phones be required to register with a proxy server and which codec will the phones use when initiating a call).
By maintaining these parameters in the default configuration file, you will be able to perform global changes, such as upgrading the image version, without having to modify the phone-specific configuration file for each phone.
Enter the name of the image version (as it is released by Cisco). Do not enter the extension. You cannot change the image version by changing the file name because the version is also built into the file header. Trying to change the image version by changing the file name will cause the firmware to fail when it compares the version in the header against the file name.
Step 2 Save the file with the same file name, SIPDefault.cnf, to the root directory of your TFTP server.
The following is an example of a SIP default configuration file:
In the phone-specific SIP configuration file, define the parameters that are specific to a phone such as the lines configured on a phone and the users defined for those lines.
Step 2 Save the file in the root directory of your TFTP server, naming it "SIPXXXXYYYYZZZZ.cnf" where XXXXYYYYZZZZ is the MAC address of the phone. The MAC address must be in uppercase and the extension, cnf, must be in lower case (for example, SIP00503EFFD842.cnf).
The following is an example of a configuration file:
If you did not configure the SIP parameters via a TFTP server, you must manually configure them after you have connected the phone as described in the "Connecting the Phone" section.
Step 2 Highlight SIP Configuration. The SIP Configuration menu is displayed.
Step 3 Highlight Line 1 Settings.
Step 4 Press the Select soft key. The Line 1 Configuration menu is displayed.
Step 5 Highlight and press the Select soft key to configure the following parameters:
Step 6 Press the Back soft key to exit the Line 1 Configuration menu.
Step 7 To configure the second line on the phone, highlight Line 2 Settings.
Step 8 Press the Select soft key. The Line 2 Configuration menu is displayed.
Step 9 Repeat Step 5 and Step 6, then continue with Step 10.
Step 10 When done, press the Save soft key to save your changes and exit the SIP Configuration menu.

Caution When you have completed your changes, ensure that you lock the phone as described in the "Locking Configuration Mode" section. |
|
Note This section describes how to configure the basic network parameters that are required for the phone to operate on the network. For a complete list of the network parameters that you can configure, see the "Modifyin g the Phone's Network Settings" section. |
The network parameters include those parameters that must be configured on a phone for the phone to operate in an IP network. You can configure the required network parameters via DHCP or manually configure them after you have connected the phone to a power supply.
The following parameters must be defined for your phone to establish network connectivity:
When configuring the network parameters of an IP phone, adhere to the following guidelines:
|
Note By default, DHCP is enabled on your phone. Before you can manually configure the network parameters, you must disable DHCP after connecting your phone to a power supply. |
If you are using DHCP to configure the network parameters, configure the following DHCP options on your DHCP server before you connect your Cisco SIP IP phone:
If you are not using DCHP to configure your network parameters, you must manually configure them.
Step 2 Highlight Network Configuration.
Step 3 Press the Select soft key. The Network Configuration menu is displayed.
Step 4 Highlight DHCP Enabled.
Step 5 Press the No soft key. DHCP is now disabled.
Step 6 Highlight and configured each of the following parameters:
Step 7 When done, press the Save soft key. The phone programs the new information into Flash memory and resets.

Caution When you have completed your changes, ensure that you lock the phone as described in the "Locking Configuration Mode" section. |
You must connect the phone to the network and to a power source before using it.
See "Connecting to the Network" section for more information on the network port.
Step 2 Connect the handset and headset to their respective ports.
See "Using a Headset" section for more information on the headset port.
Step 3 Connect a Category 3 or 5 straight-through Ethernet cable from another network device, such as a desktop computer, to the access port on the phone (optional).
See "Connecting to the Network" section for more information on the access port.
Step 4 Connect the power plug to the Cisco AC Adapter port (optional).
See "Connecting to Power" section for more information.
The Cisco SIP IP phone includes an adjustable footstand. When placing the phone on a desktop surface, you can adjust the tilt height to several different angles in 7.5 degree increments from flat to 60 degrees. Alternatively, you can mount the phone to the wall using the footstand or using the optional locking accessory.
Adjust the footstand to the height that provides optimum view of the display and use of the buttons and keys.
To adjust the phone placement on the desktop:
Step 2 Adjust the footstand to its desired height and release the knob.
You can mount the Cisco SIP IP phone on the wall using the footstand as a mounting bracket, or using the optional locking bracket. Use the following procedure to mount the phone on the wall using the standard footstand. To use the optional locking bracket, refer to the Installing the Wall Mount Kit for the Cisco IP Phone document.
Following are the tools and parts required for a typical Cisco SIP IP phone installation:
Step 2 Adjust the footstand so it is flat against the back of the phone.
Step 3 Modify the handset rest so that the handset remains on the ear-piece rest when the phone is vertically placed.
a. Remove the handset from the ear-piece rest.
b. Locate the tab (handset wall hook) at the base of the ear-piece rest.
c. Slide this tab out, rotate it 180 degrees, and reinsert it.
Step 4 Insert two screws into a wall stud, matching them to the two screw holes on the back of the footstand.
The keyholes fit standard phone jack mounts.
Step 5 Hang the phone on the wall.
After the phone has power connected to it, the phone begins its startup process by cycling through these steps:
1. These buttons flash on and off in sequence:
2. The Cisco Systems, Inc. copyright displays on the LCD.
3. These messages display as phone starts up:
4. The main LCD screen appears displaying:
If the phone successfully passes through these stages, it has started up properly.
As you configure your phone's settings via the menu interface, follow these guidelines:
The Cisco SIP IP phone ships with two ring types: Chirp1 and Chirp2. By default, your ring type options will be those two choices. However, using the RINGLIST.DAT file, you can customize the ring types that are available to the Cisco SIP IP phone users.
Step 2 Using a ASCII editor, open the RINGLIST.DAT file and for each of the ring types you are adding, specify the name as you want it to display on the Ring Type menu, press Tab, and then specify the filename of the ring type. For example, the format of a pointer in your RINGLIST.DAT file should appear similar to the following:
Step 3 After defining pointers for each of the ring types you are adding, save your modifications and close the RINGLIST.DAT file.
