Back in they day with the older 186 & 187s, there was this issue where the ATA would lose registration if the second/other port was not configured with a DN.
If that is the case, try and configure the other port and see if that improves your experience.
It looks like someone has reported a similar ATA issue for the ATA190, but not much detail included with this bug report: https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvk29369/?rfs=iqvred
Also, and I can’t recall the bug kit number, there used to be this issue with ATAs using the default Common Phone Profile setting; if you changed it to anything but whatever the default was, it improved the condition.

Does anyone else out there ever have to do a hard reset on Cisco ATA devices because all of a sudden the ports are not registered in Call Manager? We have a few buildings this happens often in. We have to walk to the device and reset it. This happens for any type of ATA we use; 186, 187 or 190.
Yup, we’re running 186s and 187s and had this constantly until I put a scheduled job on on the callmanager to restart all of them every Sunday morning at 3am. The weekly restart sorted the problem.
