[cisco-voip] trying to setup dhcp scope for iphones on dc

[Mike Armstrong]

We have IP helper-addresses configured on the VoIP VLAN interface on our 
core 3550 switch; we used to use a router but it was configured in the same 
way.

interface Vlan102
 ip address 10.251.10.3 255.255.254.0
 ip helper-address 10.230.48.200
 ip helper-address 10.230.48.199

The DCs are the DHCP servers, serving split DHCP scopes.  I'm pretty sure I 
can't paste a screenshot of the Windows config into a message for this list, 
but I'll send you a private e-mail with it in it.
