No auth session for non dot1x device behind phone

I have a 3560 running 15.0 code configured for dot1x and mab auth with ISE 1.2.  We're having trivial experiences with the auth session starting for a non dot1x device connected behind a phone that has already passed MAB.  There does not appear to be an auth session starting for the device, but it acquires an IP and traffic is subjected to the ACL-DEFAULT on the port, but since no auth session, there is no web-auth redirect.  ARP shows the device as well as IP Device Tracking.  A non-dot1x device connected directly to the port works as expected.  A dot1x device behind the phone works fine.  Any suggestions would be appreciated
