Why Using a Provisioning Server?
You can use a provisioning server to configure your IP phones. A provisioning server allows for
flexibility in upgrading, maintaining and configuring the phone. Boot files, configuration files
and resource files are normally located on this server.
When IP phones are triggered to perform auto provisioning, it will request to download the
boot files and configuration files from the provisioning server. During the auto provisioning
process, the IP phone will download and update configuration files to the phone flash. For
more information on auto provisioning, refer to Yealink SIP IP Phones Auto Provisioning
Guide_V81 .The IP phones can be configured to periodically upload the log files to the
provisioning server or specific server, which can help an administrator more easily find the
system problem and fix it. For more information on log files, refer to Viewing Log Files on page
963. The IP phones can also be configured to upload the contact file to the provisioning server
or specific server, avoiding the loss of the local contacts. For more information, refer to Backing
up the Local Contacts on page 367.
Supported Provisioning Protocols
IP phones perform the auto provisioning function of uploading log files (if configured),
uploading contact files (if configured), downloading boot files, downloading configuration files,
downloading resource files and upgrading firmware. The transfer protocol is used to download
files from the provisioning server. IP phones support several transport protocols for
provisioning, including FTP, TFTP, HTTP, and HTTPS protocols. And you can specify the
transport protocol in the provisioning server address, for example, http://xxxxxxx. If not
specified, the TFTP protocol is used. The provisioning server address can be IP address, domain
name or URL. If a user name and password are specified as part of the provisioning server
address, for example, http://user:pwd@server/dir, they will be used only if the server supports
them.
Note
Configuring a Provisioning Server
The provisioning server can be set up on the local LAN or anywhere on the Internet. Use the
following procedure as a recommendation if this is your first provisioning server setup. For
more information on how to set up a provisioning server, refer to Yealink SIP IP Phones Auto
A URL should contain forward slashes instead of back slashes and should not contain spaces.
Escape characters are not supported.
If a user name and password are not specified as part of the provisioning server address, the
User Name and Password of the provisioning server configured on the phone will be used.
There are two types of FTP methods—active and passive. IP phones are not compatible with
active FTP.
