T46G Not Time Syncing to DHCP or NTP

[pete333]

Hello,

I have a problem with my phone Yealink SIP-T46G.
Firmware version 28.80.0.80
DHCP Time = Enabled, have also tried disabled
Primary Server = 0.ca.pool.ntp.org
Secondary Server = 1.ca.pool.ntp.org

Does not do any sort of sync at all. Like the function does not work. Only way I can change time is with manual settings.

I followed the steps down, but still the same problem:
------------------------------------------------------
1.check if you have enable "DHCP time" feature,if yes,please disable that,then test again. - Tried both, no luck!
2.check if you select a correct time zone? - Yes and have tried multiple
3.check if your NTP sever address is correct? - yes and have tried multiple.

Thank you
