Timezone problem on Yealink phones when +1:00 Swiss (Bern) is set

[Jérôme Wentzel]

Hello,

We encountered DST problems on some phones recently.

When 3CX timezone is set to "+1:00 Swiss (Bern)" (in the settings / Language & Office Hours Settings ) -> yealink phones are not provisioned correctly
It takes the wrong location -> Namibia(Windhoek) (see bellow)

We had to choose another country in the timezone to solve issues with certain phones.

We identified two problems:

- 3CX Template generation.
The template does not contain the right "transform" in the section <timezoneParams param="time_timezone_yealink">
I could not find an option for the "timezone Swiss(Bern)"



- Namibia(Windhoek) is not GMT+1:
Be it in the "transform rules or in teh Yealink phones, if I refer to https://www.timeanddate.com/time/map/#!cities=266 I see that Namibia(Windhoek) is GMT+2


I cannot say why we just have the problem now, because the template did not change since last update.

I will be really happy if anybody has an idea why this happens and can confirm the problem

Best regards

Hello,

This issue is already fixed in the Update 7 (Alpha) version of the 3CX Phone System.
The main issue here was the absence of the "GMT+1 Swiss (Bern)" timezone from the Yealink provisioning templates.
After getting appropriate information from the Yealink team, we added the mentioned timezone parameter to the provisioning templates.
