[cisco-voip] Best practices for a 7936?

[Jonathan Charles]

Yeah, since the 7935/36 are not made by Cisco, they tend to not do CDP very
well.

I have found that they have a great tendency to pickup an IP on the data
VLAN if the switchport is not configured explicitly as an access port on the
voice vlan.

It just simplifies everything.
