Supported Provisioning Protocols
Yealink Teams IP Phones support several transport protocols for provisioning:
• Trivial File Transfer Protocol (TFTP)
• File Transfer Protocol (FTP)
• Hyper Text Transfer Protocol – Secure (HTTPS)
• File Transfer Protocol – Secure (FTPS)
Note: There are two types of FTP methods—active and passive. The phones are not compatible with active
FTP.
You can specify the transport protocol in the provisioning server address, for example, http://xxxxxxx. If not
specified, the TFTP protocol is used.
Supported Provisioning Server Discovery Methods
After the phone has established network settings, it must discover a provisioning server to obtain software updates
and configuration settings.
The phone supports the following methods to discover the provisioning server address:
• DHCP: DHCP option can be used to provide the address or URL of the provisioning server to the phones. When
the phone requests an IP address using the DHCP protocol, the resulting response may contain option 66 (for
IPv4) or the custom option (if configured) that contains the provisioning server address.
• Static: You can manually configure the server address via phone user interface or web user interface.
