What's New

This release includes the new EncryptKeyEx configuration parameter. This parameter provides a stronger profile encryption key than the previous EncryptKey parameter.

The syntax for the EncryptKeyEx parameter is as follows:

EncryptKeyEx:RC4key[/mac_address]

where:

•RC4key is the RC4 encryption key, specified as a hex string of 1 to 64 characters.

•/mac_address is the optional six-byte MAC address of the phone that will download the profile. You can use this option to allow only a certain phone to download a profile. This optional MAC address is preceded by a slash (/).

To use the EncryptKeyEx parameter, you must create a new profile that can encrypted and decrypted by this parameter.

If the EncryptKeyEx parameter is set to 0:

•When the phone powers up, it will make a request to the TFTP server for the configuration profile ldmac_address (where mac_address is the MAC address of the phone), or for the value specified in the DHCP bootfile option field if one is provided.

•The value of the EncryptKey (if nonzero) will be used to encrypt the profile.

If the EncryptKeyEx parameter is set to a nonzero value:

•When the phone powers up, it will make a request to the TFTP server for the configuration profile ldmac_address.x (where mac_address is the MAC address of the phone)

•The value of EncryptKeyEx will be used to encrypt the profile.

To generate the profile for the EncryptKeyEx format, you must download and use the cfgfmt tool version 2.1a. This tool will create two configuration profiles, one in the ldmac_address format and one in the ldmac_address.x format.

The EncryptKeyEx parameter can be set through the web page configuration method or through the more scalable TFTP provisioning method.

Example 1

For this example, assume that:

•A new phone has a firmware version earlier than 1.0(1)

•The phone needs to upgrade to firmware version 1.0(1)

•The phone needs to use EncryptKeyEx to encrypt its profile.

•The MAC address of the phone is 102030405060:

To upgrade this example phone and use the EncryptKeyEx parameter, follow these steps:

1. Create a new profile from the sccp_example.txt profile file. Name the new profile ld102030405060.txt.

2. Modify ld102030405060.txt with the appropriate parameter values.

Keep EncryptKey value as 0 since the phone does not yet have an EncryptKey value.

Set the EncryptKeyEx parameter to the desired encryption key for the profile. You can also optionally restrict the EncryptKeyEx value to be applicable only to the phone with a particular MAC address. For example, if the desired key value is 231e2a7f10bd7fe, specify EncryptKeyEx as:

EncryptKeyEx:231e2a7f10bd7fe/102030405060

3. Update the upgradecode parameter to instruct phone to upgrade to firmware version 1.0(1) through TFTP configuration. For example:

upgradecode:3,0x301,0x400,0x200,0,69,0x030909a,CP7905010202SCCP031217B.sbin

4. Run the cfgfmt tool as follows:

cfgfmt -g phone102030405060.txt ld102030405060

This command will generate the files ld102030405060 and ld102030405060.x. The file ld102030405060 is unencrypted.

---

Note Certain parameters, specified in the ptag.dat file used by cfgfmt tool, are marked as sensitive information. These parameters include UIPassword, UID, and PWD0. Those parameters are not included in the ld102030405060 file because the -g switch is specified.

---

The file ld102030405060.x is encrypted with EncryptKeyEx value.

Place these two files in the TFTP server that the phone will contact for its profile.

When the phone powers up, it will obtain its IP from the DHCP server. If the DHCP server specifies the TFTP server address, the phone will contact the TFTP server obtained from DHCP because it is not preconfigured with a TFTP server address. The boot process will be as follows:

–Download ld102030405060

–Apply parameter values in the ld102030405060 file to the phone, but ignore the EncryptKeyEx parameter (because the older firmware in the phone phone does not understand the EncryptKeyEx parameter).

–Upgrade to the 1.0(1) firmware load

–reboot

–Download the ld102030405060 file

–Apply EncryptKeyEx value to the phone

–Reboot

–Provision EncryptKeyEx so from now on, the phone will download the ld102030405060.x file at each time it reboots or requests a new configuration file.

Although the EncryptKeyEx is encrypted in the ldmac_address file and the ldmac_address file does not contain other sensitive information, for absolute safety, Cisco recommends that you preprovision the phone this way in a private network or remove the ldmac_address file after EncryptKeyEx is provisioned.

Example 2

For this example, assume that:

•A new phone is already deployed with the EncryptKey value set

•The a firmware version earlier than 1.0(1)

•The phone needs to upgrade to firmware version 1.0(1)

•The phone needs to use EncryptKeyEx to encrypt its profile.

To upgrade this example phone and use the EncryptKeyEx parameter, follow the steps in Example 1, with the following exception:

In Step 1, make the new EncryptKey value equal to the previously provisioned EncryptKey value. The phone expects the ldmac_address file to be encrypted with EncryptKey and must use this key to decode the ldmac_address file and begin using the ldmac_addres.x file encrypted with EncryptKeyEx.

Installing Required Firmware for the Cisco IP Phone

Before using the Cisco IP Phone 7905G for H.323, you must install the latest firmware image on the phone. For instructions, refer to Cisco IP Phone 7905G Administration Guide for H.323.

The firmware image names are:

CP7905010001H323031212A.sbin

CP7905010001H323031212A.zup

---

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 version and the latest .zup version of a firmware image. After a phone upgrades to the latest .zup firmware image, it will request .sbin firmware images for future firmware upgrades. If a phone upgrades to the latest .zup firmware image, 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.

TAC Case Priority Definitions

To ensure that all cases are reported in a standard format, Cisco has established case priority definitions.

Priority 1 (P1)—Your network is "down" or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.

Priority 2 (P2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.

Priority 3 (P3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.

Priority 4 (P4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
