Chapter 6 Configuring the Cisco IP Phone Models 7905G and 7912G Using a TFTP Server

Setting Up the TFTP Server with Cisco IP Phone Software

Setting Up the TFTP Server with Cisco IP Phone Software

Before you can use a TFTP server to configure a Cisco IP Phone, the firmware image that you are using for the phone must exist on the TFTP server. To obtain the correct firmware image and install it on the TFTP server, perform the following steps.

Note You must be a registered Cisco.com user to download the firmware image.

Procedure

Step 1 Go to the following URL:

http://www.cisco.com/kobayashi/sw-center/sw-voice.shtml

Step 2 Download the zip file that contains the software for the applicable release and firmware image you are using. The contents of each file are described next to the file name.

Note A firmware image can contain a signature that allows a phone to verify the authenticity of the image. A firmware image with such a signature has the extension .sbin. A firmware image without such a signature has the extension .zup. For the Cisco IP Phone 7905G, you should obtain both the

.sbin and the .zup versions of a firmware image. After a phone upgrades to a .zup firmware image, it will request .sbin firmware images for future firmware upgrades. If a phone upgrades to a .zup firmware image released after March 26, 2003, the phone cannot be upgraded or downgraded to any other .zup firmware image. In addition, a phone cannot be downgraded from a .sbin firmware image to a .zup firmware image. (The

Cisco IP Phone 7912G is distributed with a .sbin firmware image.)

Step 3 Extract the firmware files onto the TFTP server.

This server should be the same one that will contain the binary profile file that you create as described in this chapter.
