If you are going with the Cisco CME system, which is probably about as good as you're going to get in an SMB-designed VOIP system, then there is absolutely no reason to worry about physically segmenting the network. Setup VLANs on the switch and then you can plug your PC's into the back of the phones and the phones into the network jack on the wall. This method reduces wiring costs, and eases manageability.
