HP2920 Tagged / Untagged

[intel233]

I have a new 2920 switch. I configured it as below. My question is for each VLAN do I need to tag / untag each port like I did in VLAN 3? I am very confused my this. I have VOIP phones (VLAN6) and the PC's get connected into the phone. My data VLAN is VLAN3
I am also connecting this switch to my HP 2920 Stack (4 Hp2920 in the stack). Right now I just went from 4/40 in the stack to port 43 in the new switch and people can connect to the network and the phone works.
vlan 1

So I tagged port 2,9 in VLAN 6 and when I went to the config on the phone it still says VLAN0. Is this because the Uplink which is Port 44 in the new switch is not config as a trunk port? If I config that as trk2 then I also need to config the other switch port (switch 4 in the stack) as the same trk2?
