About TFTP Server

CIC provides a built-in TFTP server. When a Polycom phone is switched on, it downloads its configuration files from the TFTP root directory. By default, Polycom phones also write log files to this TFTP directory (if the TFTP server is configured to accept write operations).

Note: The TFTP server does not directly facilitate the creation or modification of Polycom phone configuration files. The TFTP root directory is available only by means of the network (if you set it up as a shared folder) or by direct access to the CIC server. The TFTP server is not used for managed phones.

TFTP server subdirectories

By default, the IP phone files are stored in the main TFTP server directory. Or you can use separate subdirectories on the TFTP server for phone logs, contact directories, and override files. Specify these subdirectory names in the Polycom master configuration file (<Ethernet address>.cfg) to make the phones write the files to the appropriate subdirectories.

These types of files can be stored in subdirectories on the TFTP server .

File Type	Description
Phone Logs	Both startup and application event log files are maintained for each phone. These event log files are stored in the flash file system on the phone and are periodically uploaded to the TFTP server. The event log files are `<Ethernet address>-boot.log` and `<Ethernet address>-app.log`.
Contact Directories	Each phone maintains a local contact directory. The person using the phone can change the directory contents at will. Changes are stored in the flash file system on the phone and are backed up to the boot server copy of `<Ethernet address>-directory.xml` (if configured). Only updated contact directories are stored in this subdirectory. When the phone starts up, the boot server copy of the directory, if present, replaces the local copy.
Overrides	The `<Ethernet address>-phone.cfg` files are also referred to as boot server override files. Configuration overrides made at the phone are written to this subdirectory. Storing the updated phone configuration files in a specific subdirectory helps to separate them from the files you often modify which are stored in the root directory.

TFTP server interface

You can use a web-based interface for the CIC TFTP server to:

Monitor the TFTP client file transfer activity.
Specify upload file types.
Configure the upload subdirectories.

Installation and basic configuration

The CIC server install automatically installs the necessary TFTP server component files. You can use Setup Assistant to change the TFTP server Service Startup Type from Manual to Automatic. For more information, see the PureConnect Installation and Configuration Guide.

Note: If you change the TFTP server Service Startup Type, restart the service.
