hello
cucm 8.6.2
have got 5 ata-190, and all of them have one problem - it drops registration and became unregistered after some period of time. after reboot it works fine several days and then drops it again.
tried different firmware (now it is ATA190.1-1-2-005), but it doesn't help
ATA-187 works fine.
