Hi, I have to use dotx and mda with a nps Windows server and non-Cisco phone but Cisco switch (cause I have a PC connected behind a phone and both must be authenticated). I've succedded as my phone and my pc connected behind the phone suceed authentication and authorization and a "show authentication sessions" show me that authentication is right in domain DATA and VOICE. But a few minutes after, there is port violation beacuse the phone (yealink) try to authenticate again and fails this time (while it had succeeded the first time...) I really does not understand what can happen and why it's ok a frist time and ko few minutes later... Thank you for your help!
