Cisco ATA 186 and 10.1.1.1
If you notice any issues on your firewall regarding your ATA 186, it’s most likely because of a factory hardware error that causes the ATA to try to create a route to a nonexistent CCM at 10.1.1.1 as a backup. Find the IP of your ATA and type it in your browser and add /dev behind the url. On the SCCP page, change both CCM addresses to your addresses. If you only have 1 CCM, put it in both boxes.
