Configuring a Provisioning Server
Yealink IP phones support using FTP, TFTP, HTTP and HTTPS protocols to download boot files
and configuration files. You can use one of these protocols for provisioning. The TFTP protocol
is used by default. The following section provides instructions on how to configure a TFTP
server.
We recommend that you use 3CDaemon or TFTPD32 as a TFTP server. 3CDaemo and TFTPD32
are free applications for Windows. You can download 3CDaemon online:
http://www.oldversion.com/3Com-Daemon.html and TFTPD32 online: http://tftpd32.jounin.net/.
For more information on how to configure FTP and HTTP servers, refer to Configuring an FTP
Server and Configuring an HTTP Server.
Preparing a Root Directory
To prepare a root directory:
1. Create a TFTP root directory on the local system (e.g., D:\TFTP Directory).
2. Place the boot files, configuration files and resource files to this root directory.
3. (Optional.) Set security permissions for the TFTP directory folder.
You need to define a user or a group name, and set the permissions: read, write or modify.
Security permissions vary by organizations.
