2.If the Cisco CallManager configuration is correct, the Cisco 7920 should have registered with the CallManager server. You should now be able to place calls between the Cisco 7920 and your other IP Phone.

Troubleshooting

All of the troubleshooting guidelines can be found in the Troubleshooting Guidelines section at the end of this document.

Using Open Authentication, Static WEP Keys, and VLANs

This task adds support for VLANs, to build on the previous task. The implementation of VLANs requires configuration changes on the Cisco 7920 and on the Cisco Aironet 1200 AP. The 1200 AP can be configured with different SSIDs for each VLAN. For example, you can use ￿VLAN1￿ as the SSID for VLAN1 and ￿VLAN2￿ as the SSID for VLAN2. The Cisco 7920 uses its SSID to determine which VLAN that it should use. If you want the Cisco 7920 to use VLAN2 then you would configure its SSID to VLAN2.

In this example, VLAN1 is the default VLAN. The Cisco 7920 will be configured to use VLAN2, and then VLAN2 will be added to the Cisco Aironet 1200 AP.

Configuring the Cisco 7920

Note: This task uses the same WEP key that was used in the first task. Therefore, it does not include the instructions to establish the WEP key on the Cisco 7920.

This task assumes that you are using DHCP to obtain the correct IP address and default gateway for the Cisco 7920. You must also configure your DHCP server with a scope for the new VLAN. Refer to Using One DHCP Server for Voice and Data Networks for more information on DHCP. If you use a static IP address and default gateway address, then you must change the current IP address on the System Parameters tab in the Cisco 7920 Configuration Utility to a legitimate address on the new subnet, before you export the new configuration to the Cisco 7920. Change the IP address between Steps 11 and 12 in the next procedure.

Step−by−Step Instructions

The instructions in this section guide you through the minimum steps that are required to configure the Cisco IP Phone 7920 to use VLAN2￿s SSID.
