If you leave it blank, the phone will upload the local log files to the provisioning server.
If you configure a relative URL (for example, /upload), the phone will upload the local log files by
extracting the root directory from the access URL of the provisioning server.
If you configure an absolute URL with the protocol (for example, tftp), the phone will upload the local
log files using the desired protocol. If no protocol, the phone will use the same protocol with auto pro-
visioning for uploading files.
Example:
static.auto_provision.local_log.backup.path = tftp://10.3.6.133/upload/
Note: It works only if “static.auto_provision.local_log.backup.enable” is set to 1 (Enabled).
