Hi:
I have a Client with a Yeastar u100, I installed it 3 years ago. All the Yealink IP phones were manually programmed.
Now, I am programming them with automatic parameters and I see that time and date do not synchronice between Yeastar IPPBX and Yealink IP phones.
Yeastar U100 firmware is 15.19.0.43
What can I do...?
Best regards
