Troubleshooting Phones
If a phone is not functioning properly, follow the steps below to check the status of the connection. Refer
to Modifying Existing Phones on page 31 and Resetting a Phone to Factory Default on page 32 for
configuration assistance.
1. Check the line keys for the phone’s extension to see if it is currently registered with the
NetVanta 7100. If the extension does not appear on the line key, proceed to the next step.

2. Refer to Rebooting a Phone on page 40 to manually reboot your phone. Phone key combinations
are available to manually reboot phones. Also see Table 5 on page 40 for a list of reboot key
combinations. Simultaneously hold the appropriate keys until the confirmation tone is heard
(about 3 seconds). The reboot process may take several minutes.
3. Place test calls once the phone has been rebooted to determine whether the reboot resolved the
problem.
4. If rebooting the phone did not resolve the issue, contact your NetVanta 7100 system administrator.
