Dont confuse VOIP with AVVID/IP Telephony.. To run IP Telephony over a cat 5K, use a secondary IP address on the router interface that routes the vlan for the switch in question. You will need a DHCP server that has both primary and secondary scopes, and the primary will service the data devices and the secondary will service the phones based the dhcp-150 request coming from the phone.
