I have updated Snom phones from unsupported firmware version 184.108.40.206 to latest firmware 220.127.116.11. It seems, that VLAN support definietly stopped to work. When I plug Snom set to DHCP (no VLAN settings) into the ethernet set to trunk mode (211 vlan native, available 141,211), the Snom doesnt get DHCP. If I plug It into the access mode switch (only one vlan), It gets successfully DHCP address. After that, when I set VLAN id to the corresponding vlan in that port (through 3CX/dirrect phone setup through browser IP address of Snom phone), the DHCP stop to work again (I get no address from DHCP server). Everything has worked with older versions (<18.104.22.168) Is that a firmware bug ?
