Why is the permission denied when uploading files to the root directory of the FTP server?
 Ensure that the complete path to the root directory of the FTP server is authorized.
 Check security permissions on the root directory of the FTP server, if necessary, change the
permissions.
Why doesn’t the IP phone obtain the IP address from the DHCP server?
 Ensure that settings are correct on the DHCP server.
 Ensure that the IP phone is configured to obtain the IP address from the DHCP server.
Why doesn’t the IP phone download the ring tone?
 Ensure that the file format of the ring tone is *.wav.
 Ensure that the size of the ring tone file is not larger than that the IP phone supports.
 Ensure that the properties of the ring tone for the IP phone are correct.
 Ensure that the network is available and the root directory is right for downloading.
 Ensure that the ring tone file exists on the provisioning server.
Why doesn’t the IP phone update configurations?
 Ensure that the configuration files are different from the last ones.
 Ensure that the IP phone has downloaded the configuration files.
 Ensure that the parameters are correctly set in the configuration files.
 Ensure that the value of the parameter “static.auto_provision.custom.protect” is set to 0. If it
is set to 1, the provisioning priority is shown as follows: phone/web user interface >central
provisioning >factory defaults. A setting you make using a lower-priority method does not
apply to or override a duplicate setting made using a higher-priority method.
