W90 LAN sync

[nolto]

Yealink responded to our request as follows:

1. you need to confirm with the switch manufacturer whether the switch supports PTP. If it does not support it, you need to replace it with a switch that supports PTP. If it does, you need to enable PTP.

2. Please go to the DM web page, under Base Station Group, after checking several parameters in the box (such as the attached picture), provide a screenshot of the base status

3. LAN Sync has high network requirements. It is recommended to use this method if DECT Sync can be used.
