Hi, I hope you are doing well. We have a problem with the footswitch and Fanvil IP phones. I have configured Voice and Data VLAN separately on Fortilink as a sub-interface. Also, I have configured Zones for different subinterfaces. Voice and Servers are under Server zones. For voice and Data, VLAN DHCP is configured on windows server 2019 and I indicate DHCP server on each interface as DHCP relay. But in some cases, IP phones don't get IP addresses from the server. Also, I configured the LLDP profile for IP phones.
