Administrator’s Guide for SIP-T2 Series/T19(P) E2/T4 Series IP Phones

001565770984.cfg file you want the IP phone to download:

auto_provision.custom.protect=1

auto_provision.custom.sync=0

firmware.url = tftp://192.168.1.211/44.80.0.5.rom

2. Trigger the IP phone to perform the auto provisioning process. For more information

on how to trigger auto provisioning process, refer to

Triggering the IP Phone to

Perform the Auto Provisioning

section in

Yealink_SIP-T2_Series_T19(P)

E2_T4_Series_IP_Phones_Auto_Provisioning_Guide

During auto provisioning, the IP phone first downloads the y000000000044.cfg file,

and then downloads firmware from the root directory of the provisioning server.

The IP phone reboots to complete firmware upgrade, and then starts auto

provisioning process again which is triggered by phone reboot (the power on mode

is enabled by default). It downloads the y000000000044.cfg and 001565770984.cfg

files in sequence, and then updates configurations in the downloaded configuration

files orderly to the IP phone system. As the value of the parameter

“auto_provision.custom.protect” is set to 1, configurations in the

001565770984-local.cfg file saved on the IP phone are also updated.

The IP phone starts up successfully, and personalized settings are kept after auto

provisioning. When a user customizes feature configurations via web/phone user

interface, the IP phone will save the personalized settings to the

001565770984-local.cfg file on the IP phone only.

Note

If value of the parameter “auto_provision.custom.protect” is set to 0, the personalized

settings in the 001565770984-local.cfg file will be overridden after auto provisioning, no

matter what the value of the parameter “auto_provision.custom.sync” is.

Note

In this scenario, the IP phone will not upload the MAC-local.cfg file to provisioning server

and request to download the MAC-local.cfg file from provisioning server during auto

provisioning.

If a configuration item is both in the MAC-local.cfg file on the IP phone and Common CFG

file/ MAC-Oriented CFG file downloaded from auto provisioning server, setting of the

configuration item in the MAC-local CFG file will be written and saved to the IP phone

system.

If a configuration is modified via both web user interface and phone user interface, the

later modification will prevail.

refer to Appendix E: Auto Provisioning Flowchart (Keep user personalized configuration

settings) on page 767.
