Redundant Design issue

 I have a design issue that is stumping me and was wondering if any could
offer any thoughts on a possible solution. Here is the overview:

Dual 6509's at the core

VLAN 150 for data

VLAN 15 for Voice

2811 CME/CUE with FE0/0 and 2 sub-interfaces connecting to trunk port on
6509A

3560 connected to core 6509's for PoE connections to the IP phones

We want a redundant connection from 6509B into the 2811. The issue is that in
order to make it work, I would need to (and can) create another VLAN and
create a trunk between 6509B and the 2811 FE0/1. However, the issue I will
run into is trying to make the 2nd sub-interface a member of the VOICE VLAN,
not to mention that fact that the phones will only communicate with the 1 IP
address on the VOICE VLAN that is assigned to the sub-interface on FE0/0.

Thanks in advance,

Nathan Richie
