Daylight Savings Time not working on Yealink T46G

[atcom]

We've chosen time zone -07:00 and enabled daylight savings but the phones show non-DST time. The setting shown in the phones web GUI is "-7 United States-Mountain Time" and DST mode is "Automatic".

Changing the time zone in the phone's web GUI to "-7 Canada(Edmonton,Calgary)" and leaving DST mode set to "Automatic" resolves the issue.

Firmware:
SIP-T46G 28.72.0.45

I certainly did not - we don't expect to have to factory default every phone we have in the field when there's a firmware update! PLEASE COMMENT!!!

Hello ,
sorry but the daylight savings is configured in the AutoDST.xml and sometimes the customer may change the setting, so you upgrade the phone version, the AutoDST.xml won't cover the current setting the customer using unless you reset the phone to factory default.
so in this case, we would suggest you reset the phone to factory default or you can upgrade the AutoDST.xml through auto provisioning file.

Sorry for the inconvenient.
Best Regards!

Thanks Flora, I'll give the auto provisioning a try.

I assume I should use:

Code:

auto_dst.url = tftp://xxx.xxx.xxx.xxx/AutoDST.xml

in the configuration file?

[Flora_Yealink]

Yes, correct ,just like configure it auto_dst.url =http://10.2.5.174:8080/AutoDST.xml in the provisioning file.
