[cisco-voip] Power over Ethernet

Okay so this is a newbie question, but I can't seem to find the answer.

I have an MGCP Gateway on a 2811
this is a small 5 person office so they have an Ethernet module on the
router. (NM-16ESW) with a power card (PPWR-DCARD-16ESW).

This weekend I tried to cut over the site and I can't get power to the
phones.

the Config looks like this:

Interface FastEthernet1/1
decription Sue's Phone and PC
switchport access Vlan 4
switchport voice vlan 3
duplex full
speed 100
power inline auto
mls qos cos override
spanning-tree portfast

according to the router my options are power inline (auto, never).  Do I
need cdp enabled on the port to detect the phone?  How do I get power to the
phones?

Much appreciated
