ITL Issue with CUCM 8.6(2a)SU3

Hi, We have a cluster of 6 nodes pub, 2 standalone ccm, 2 (ccm+tftp) and 1MoH server.

when we move a phone from one device pool to another, the phone displays "Registration Rejected:Security Error"

I tried deleting the ITL files on the phones but still no luck. with 'show itl' command, we see that the 'System Administrator Security Token' and the 'TFTP' function ITL Record parameters twice with two different certificates in  all the nodes.

On another working cluster, the ITL Records of System Administrator Security Token' and the 'TFTP' function can be seen only once.

any idea why this difference? The change in CUCM happened before this issue was that we changed the DSCP enterprise parameter and reset all the phones and restarted the CCM service on all the 4 nodes.

I would start by restarting the TVS and TFTP services on the servers within the cluster.

Thanks,
