This chapter explains how to configure the Cisco IP Phone using a Trivial File Transfer Protocol (TFTP) server. This configuration method is useful when you have many Cisco IP Phones because you can use a TFTP server for remote, batch configuration of the phones. The TFTP server can also host one unique configuration file for each phone.
Chapter 6 Configuring the Cisco IP Phone Models 7905G and 7912G Using a TFTP Server Using Profiles with TFTP Configuration If you are not using a Dynamic Host Configuration Protocol (DHCP) server, you must manually define IP addresses, subnet masks, and gateways for the phones before you can access profiles.
Page 95
Chapter 6 Configuring the Cisco IP Phone Models 7905G and 7912G Using a TFTP Server Using Profiles with TFTP Configuration TFTP configuration works as follows: The Cisco IP Phone model 7905G will try to download the profile ldxxxxxxxxxxxx from the TFTP server. The Cisco IP Phone model 7912G will try to download the profile gkxxxxxxxxxxxx from the TFTP server.
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.

Standard DHCP option 66 (TFTP server name) • If you use DHCP option 150, the Cisco IP Phone will ignore DHCP option 66. However, if you use DHCP option 66, you must turn off DHCP option 150 or set its value to 0.
Page 99
After you complete these steps, the Cisco IP Phone will contact the DHCP server for the IP address of the TFTP server that contains the Cisco IP Phone profile. If the DHCP Server is not Under the Control of the Cisco IP Phone Administrator If you as the Cisco IP Phone adminstrator do not control the DHCP server, you must manually configure the URL of the TFTP server.
Chapter 6 Configuring the Cisco IP Phone Models 7905G and 7912G Using a TFTP Server Configuring the Cisco IP Phone to Obtain its Configuration File from the TFTP Server can be set in the bootfile name field of the DHCP header. This field is limited to 31 characters, even though the DHCP specification allows for a longer bootfile name.

Chapter 6 Configuring the Cisco IP Phone Models 7905G and 7912G Using a TFTP Server Creating or Updating a Profile you use the parameter tag file called sip_ptag.dat, which Cisco provides. You can rename sip_ptag.dat to ptag.dat before you run the cfgfmt.exe tool, or you can use the cfgfmt.exe tool -t option to specify the file name sip_ptag.dat.
Chapter 6 Configuring the Cisco IP Phone Models 7905G and 7912G Using a TFTP Server Creating or Updating a Profile • A parameter value must be one of the following types: Alphanumeric string – – Numeric digit string – Array of short integers IP address (for example, 192.168.2.170)

• Creating a Default Profile You can create a default profile, called lddefault.cfg for the Cisco IP Phone 7905G, or gkdefault.cfg for the Cisco IP Phone 7912G, that is common to all Cisco IP Phones of the same model. This profile is applied to a phone only if a phone-specific profile (ldxxxxxxxxxxxx or gkxxxxxxxxxxxx) does not exist for the phone on the TFTP server when the phone powers up.
Page 106
Creating or Updating a Profile The following steps explain how to create a default profile, how to convert it to binary format, and how to store it on the TFTP server so that the Cisco IP Phone will download it during the boot-up process: Procedure Use a text editor to open the sipexample.txt file or to open another existing text...
Using Encryption The EncryptKey parameter encrypts binary files that are transferred over TFTP. You can change this key for each Cisco IP Phone so that only one specific phone can decode the information. By default, the phone-specific profile is not encrypted. If encryption is required, you must manually configure the phone with the encryption key.

Chapter 6 Configuring the Cisco IP Phone Models 7905G and 7912G Using a TFTP Server Using Encryption The EncryptKey parameter or the profile Encrypt Key parameter and the encryption key used in the cfgfmt tool command syntax must match.
