Note
Scenario Conditions:

SIP-T46G IP phone current firmware version: 28.80.0.80. This firmware supports keeping
personalized settings and generating a <MAC>-local.cfg file.

SIP-T46G IP phone target firmware version: 28.81.0.15. This firmware supports keeping
personalized settings and generating a <MAC>-local.cfg file.

SIP-T46G IP phone MAC: 001565770984

Provisioning server URL: tftp://192.168.1.211

Place the target firmware to the root directory of the provisioning server.
The old firmware version supports keeping personalized settings and generating a
<MAC>-local.cfg file. To keep user personalized settings after auto provisioning and upgrade,
you need to configure the value of the parameter “auto_provision.custom.protect” to 1 in the
configuration file.
Do one of the following operations:
Scenario Operations I:
1. Edit the following parameters in the y000000000028.cfg file you want the IP phone to
download:
auto_provision.custom.protect = 1
auto_provision.custom.sync = 1
firmware.url = tftp://192.168.1.211/28.81.0.15.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_T5_Series_W5_Series_IP_Phones_Auto_Provisioning_Guide_V81 .
During auto provisioning, the IP phone first downloads the y000000000028.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
The parameters described in this scenario have been changed for the phones running firmware
version 81 or later. For more information, refer to Yealink_SIP-T2_Series_T19(P)
