Yealink SIP-T31G Administrator's Guide

Administrator’s Guide for SIP-T2 /T3 /T4 /T5 /CP920 IP Phones

Yealink phones can obtain the provisioning server address during startup. Then the phones first download boot
files and configuration files from the provisioning server and then resolve and update the configurations written in
configuration files. This entire process is called auto provisioning. For more information on auto provisioning, refer
to Yealink SIP IP Phones Auto Provisioning Guide.
The phones can be configured to upload log files (log files provide a history of phone events), call log files and con-
tact files to the provisioning server. You can also configure a directory for each of these three files respectively.
