Re: Phone 7821 and 8945 become none when restart the CUCM
normally register with CUCM PUB and if PUB down will register with CUCM SUB. Yes If I rebooted the PUB will register with SUB but some phones will lose the connection with CUCM and status will be None
When Both servers down and after while both server comes up I lost a lot of 7821 + 8945 IP phones the registration with CUCM.
I saw the IP phones has the IP address from core sw DHCP but when I restart the IP phones the phone will not take the IP address until make hard reset for the phone the IP phone will take a new IP address and start registering with CUCM.
