To follow up on this, the Cisco Switches and the Cisco phones will work together to create two vlans: a prioritized vlan for the phone traffic, and a secondary 10/100 link for a computer which can be attached to the phone's second switched ethernet port. Some config is needed in the switch and router to make this happen properly. I have it running well with 79x0 phones, 3550 switch, and 1751-V router.
What this means is only one switch port is needed to run both a phone and a computer. This helps on the switch/phone ROI calcs. The PoE can also be used to power wireless access points.
