Hi ,
Were having problem with ata-190 randmoly one of the ATA goes unregistered and stays that way until I click restart on CUCM .
When I connect to the ATA I see link status connected and Registration state : Registered.
CUCM ver : 10.5.2.1000-5
ATA-190 ver 1.2.1(004) .
In our cluster were using LSC certificate but of it's not installed on the ata due this CSCuv26521 bug .
Any idea?
