Just a thought but if your switch properly tags the packets from the voice and
data Vlans, the broadcasts from the IP Phones should not cross over to the
data Vlan. We have dozens of customers setup this way and they are not having
any problems. Not sure what type of switches you are using but I would check
your switchport configuration (assuming managed switch).
