[cisco-voip] friendly windows-based CCM warning

[Paul]

If you have more than one interface on your CCM boxen, be sure to disable any other NICs if you're using a DHCP server off of one of the servers or you'll have a giant headache if any of the servers happens to reboot and acquire an address from the pool.

Your CallManager Service will refuse to start among other lovely errors that will have callmanager reinstallation nightmare images flashing through your mind.
