Cisco IP Phone 802.1x authentication with NPS

Hi All,

I would like to configure 802.1x authentication on both my Cisco ip phones and windows clients using NPS. So far i have tested the clients and it works however I am not finding any information on if NPS supports 802.1x on ip phones. Has anyone done a similar deployment using NPS. So far I am only seeing cisco ACS server being used as the policy server.
