I had installation with OC200 + EAP's. With Orange Router specially for VOIP phones.

All was working with some old D-LINK and noname chinese switches.

I changed to the TP-LINK TL-SG2218 with OMADA. Now my VOIP phones (there are preconfigured by Orange, I don't have access to configuration) can not find the IP adress from DHCP server. It seems that I need switches wotking transparent mode. It is possible to configured that in Omada?

Thanks for help
