extending a VLAN to a downstream 6224

Howdy all, i have a 6224 acting as a backbone with 4 VLAN's (1, 99, 100, & 105) plugged into a Cisco 18xx series switch (port1 below), which is acting as the Layer 3 router.

VLAN 105 is  for VoIP (Cisco UC350)

I can configure ports on the backbone for VLAN105 and if i plug a handset in, works aok.

I have another cascaded 6224 plugged into port 23 of the backbone, however i cannot reach VLAN105 from this switch.

Currently the ports between the switches are in General mode, with VLAN 105 as an allowed VLAN, but with a PVID of 1 (there are additional devices on the second switch participating in VLAN1).

Do these two ports need to be in trunk mode instead, or do i need to enable VLAN routing on the backbone 6224?
