I think, it doesn't use ITL/CTL.
Also CUCM reporting does only list the ATA191 as the only ATA supporting the "Security by default" feature

@rrighi ATAs do use ITL/CTL files. I have had to delete them in the past to move ATAs to a new cluster.
CUCM Pushes ITL by default, but CTL only when the cluster is in mixed mode (secure mode).
ATA 187 Security Troubleshooting section of the doc referenced below talks about ITL/CTL issues.

If you need to delete ITL/CTL files from your ATA 187, you need to factory reset it. Refer to link below on how to factory reset it.

On my ATA 187 I couldn't see any message saying its trying to downloaded the ITL. But I can see Ctl trying.
A To remove the CTL do a factory reset.
