Cisco 3560CX-12port Issue with Voice VLAN

    I am having a problem with our phones.  They don't work when plugged into a port controlled by clearpass 6.8.2.XXXXXXX. 

    1)  They are Avaya phones

    2)  They get their 802.1Q tag for VLAN 42 from the DHCP Server

    3)  They don't get a DHCP lease.  Nothing seems to be going over VLAN42 from the phone?

     

    I used the Solution Exchange to get my IBNS 2.0 configuration (Attached, Sanitized).  I have attached a picture of my Enforcement Profile, the two policies, and the service.  I have profiling setup and on ports that are not controlled by ClearPass, phones are working perfectly!  802.1x is working perfectly on the ports as well and assigning the correct vlan!  802.1X is working through the phone port too!  The ports that are controlled by clearpass, whenever I send a VLAN for the phone, i get an error that I can't use the same VLAN that the Voice VLAN is set to?    Also attached I have my configuration for how my 3 different ports on the switch look like.  Port 11 works fine, I modified port 10 to not use the ACL, and port 9 uses the ACL.  Both 9 and 10 are not working with my phone.  (Should I send it a different VLAN?)   I'm at a loss here.  Attached are my 3 ports and template below:

    Send "device-traffic-class=voice" rather than VLAN for VOIP. Refer pg 134 of https://community.arubanetworks.com/t5/Security/ClearPass-Solution-Guide-Wired-Policy-Enforcement/td-p/298161
