Background Information

The Cisco 7970 IP Phone calculates the time displayed on its panel based on these two parameters. Cisco CallManager Express passes these two parameters to the Cisco 7970 IP Phone during phone initialization time:

• The Coordinated Universal Time (UTC)/Greenwich Mean Time (GMT) converted from the current time on Cisco CallManager Express.

• The timezone configuration for the Cisco 7970 IP Phone on Cisco CallManager Express.

Configuration

Complete these steps on the Cisco CallManager Express to display the correct time:

1. Configure CLI type 7970 under the ephone (see arrow A in Figure 1).

   Figure 1—Ephone Configuration

   

2. Configure CLI time-zone (see A arrow in Figure 2) under the Telephony service.

   Figure 2—Time Zone Configuration

   

3. Configure the create cn command under the Telephony service to implement the change in step 1 and 2 (see arrow A in Figure 3).

Reset the Cisco 7970 IP Phone to verify the configuration. Complete these steps:

1. Hit the Setting button on the Cisco 7970 IP Phone.

2. Enter the **#** key sequence on the phone keypad to reset the phone.

   The correct time displays on the Cisco 7970 IP Phone after the reset.

Troubleshoot

Complete these steps if the time displayed on the Cisco 7970 IP Phone is incorrect:

1. Verify the phone configuration on Cisco CallManager Express.

2. Display the 7970 configuration on Cisco CallManager Express. The name is xmldefault7970.cnf.xml and is located in the system:/its/ directory. Complete these steps:

   1. Login to Cisco CallManager Express.

   2. Complete these steps to display the 7970 configuration file:

      1. Issue the cd system: command.

      2. Issue the cd its command.

      3. Issue the more xmldefault7970.cnf.xml command to dump the configuration (see arrow A in Figure 4) .

   3. Verify that the time zone parameter is correctly configured (see arrow B in Figure 4).

3. Verify that Cisco CallManager Express successfully sends the 7970 configuration file to the Cisco 7970 IP Phone. Complete these steps:

   1. Login to Cisco CallManager Express.

   2. Issue the debug tftp event command.

   3. Issue the terminal monitor command.

   4. Reset the Cisco 7970 IP Phone.

      Figure 5 shows the debugging output. If the Cisco 7970 IP Phone successfully receives its configuration file, the messages contained in arrow A appear.
