I do have a Router in the mix.
Looking into the tagging of the port aspect now.
As for this, yes, if we untag the port, then yes, we are able to get to it in that manner, but we lose connectivity to the phones and phones do not obtain DHCP info.
The odd thing is, from vlan1, I am able to ping all the phones on which get their DHCP address from the 3300 on vlan2 and the "pass-through/switch port" on the phones allow data so the routing seems fine.
I just cannot ping nor reach the 3300 from the data vlan.
