Time settings

[Harrisonm]

Good day,

How do i fix the time settings on the yealink phones Globally.All the phones are auto provisioned but all are showing 1hour early.

Are you in the right timezone?
do you have winter and summer hours?

 

[Harrisonm]

I am not sure what if i understand you. but i just disabled Daylight saving time on the phone and it works but i dont want to do it this way . I want to work on central place and apply the settings to all the phones at once . Please assist step by step.

Hi Harrisonm,

If you are running the PBX on windows please ensure that the windows timezone and date/time is correct.

Then, in the 3CX management console, go to Settings > Timezone and also ensure this is correct.

Once all is done, go to your extensions and ensure that under Phone Provisioning, the devices have "Use global timezone" selected.

If all the above is aligned as per my description, and you are also running our latest templates and firmware, then the phones should provision correctly and display the the correct time.

What timezone are you in by the way?

Linux based
CX management console, go to Settings > Timezone +2 Central Africa Time
Phone Provisioning, the devices have "Use global timezone" selected.

not all phones are running latest version of firmware (can this cause an issue)

if you have not hundred of phones to update , apply new FW to have same level on all.

It can cause an issue if the template is not compatible with the phone (due to older firmware).

- What Yealink models exactly are facing the issue?

- If you reprovision one of your phones with the latest firmware and templates will it show the correct time?

- Does the PBX server have the correct time?

- Does your network have an NTP server with incorrect time?

I did try to update the firmware on T40P from 54.82.0.20 to T40-54.84.0.15

​

and after upgrade has succeeded the phone wont register and the time was still showing wrongly.
since the phone is not registering on the new firmware - i downgraded to 54.82.0.20 and the phone is registering now.

back to square one - time is wrong on the phone

BUT WHY DID THE PHONE NOT REGISTER ON THE LATEST FIRMWARE ?

Hi Harrison,

Please provide some additional info like:

-What is your PBX version? (can be seen on the dashboard, under License)

-What is your Yealink template version? (can be seen under Settings > Templates > yealinkT4x.ph.xml)

-Are you using custom templates?

-How are phones provisioned? (LAN/SBC/STUN/VPN)

-Have you checked the time on the Linux server via command line?
