Endpoint Manager Question

Hello,

Iam trying to configure A Cisco 7906, 7945,7970,and a 7975 for use with freepbx. I dont see those models in the endpoint manager. Can someone point me in the right direction. I was able to get my 7960 to work with no problems whatsoever. However, the XML file phones are not working. any help is appreciated.

THanks
