maintaining and configuring the phone. Boot files, configuration files, and resource files are normally located on this
server.

Supported Provisioning Protocols
Yealink phones support several transport protocols for provisioning:
l Trivial File Transfer Protocol (TFTP)
l File Transfer Protocol (FTP)
l Hyper Text Transfer Protocol – Secure (HTTPS)
l File Transfer Protocol – Secure (FTPS)
Note: There are two types of FTP methods—active and passive. The phones are not compatible with active FTP.
