Hi,
I am having CUCM 8.6, and around 1200 Cisco 3905 SIP phones are registered in CUCM at different 4 locations.At all the locations other than one, any 3905 SIP phones gets into "Registering" , "Provosioning" and "Unregistering" mode, so we remove those phones and keep them standby for 2-3 days and later connect them on the same port and they gets registered.
what cause them to go in these different modes?
