Chapter 9 Troubleshooting the Cisco Wireless IP Phone 7920 Resolving Startup and Connectivity Problems Symptom: The Cisco Wireless IP Phone Does Not Register with Cisco CallManager If a phone proceeds past the first stage (authenticating with access point), and, continues to cycle through the messages displaying on the phone screen, the phone is not starting up properly. The phone cannot successfully start up until it connects to the LAN and registers with a Cisco CallManager server. These sections can assist you in determining the reason that the phone is unable to start up properly: • Registering the Phone with Cisco CallManager, page 9-5 • Checking Network Connectivity, page 9-6 • Verifying TFTP Server Settings, page 9-6 • Verifying IP Addressing, page 9-7 • Verifying DNS Settings, page 9-8 • Verifying Cisco CallManager Settings, page 9-8 • Cisco CallManager and TFTP Services Are Not Running, page 9-9 • Creating a New Configuration File, page 9-10 Registering the Phone with Cisco CallManager A Cisco Wireless IP Phone 7920 can register with a Cisco CallManager server only if the phone has been added to the server or if auto-registration is enabled. If you see the error message, "Registration Rejected," review the information and procedures in the "Adding Users to Cisco CallManager" section on page 7-13 to ensure that the phone has been added to the Cisco CallManager database. In Cisco CallManager versions earlier than 3.3(3) SR 1, the Cisco Wireless IP Phone 7920 shows up as a Cisco IP Phone 7960, because the 7920 phone device type was not available. See the "Determining the MAC Address of a Cisco IP Phone" section on page 3-10 for more information and how to correct this problem.
