Yealink IP Phones Auto Provisioning Guide

You can configure the IP phone whether to download the <MAC>-local.cfg file from the
provisioning server, and update configurations in the <MAC>-local.cfg file to protect
personalized settings after auto provisioning.
If the IP phone is configured to download the <MAC>-local.cfg file from the
provisioning server, it will download the <MAC>-local.cfg file after downloading the
Common CFG file and the MAC-Oriented CFG file.
If the IP phone is configured to protect personalized settings, it will update
configurations in the <MAC>-local.cfg file. The IP Phone updates configuration files
during auto provisioning in sequence: Common>MAC-Oriented>MAC-local. So when
configuration items in the <MAC>-local.cfg file are duplicated with the ones in the
downloaded Common CFG file or the MAC-Oriented CFG file, the settings in the
<MAC>-local.cfg file will take effect.
For more information on how to configure the IP phone, refer to Scenario A Protect
personalized configuration settings on page 50 .
After auto provisioning, you can then verify the update via phone user interface or web
user interface of the phone. For more information, refer to Yealink phone-specific user
guide.
During the auto provisioning process, you can monitor the downloading requests and
response messages by a WinPcap tool. The following shows some examples.
