Cisco 3905 SIP phones registration error

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?

Hello,

Hello,

I have the same issue with the 3905 flapping between Registered and Provisioning

CUCM Version: 8.6.2.25900-8

3905 Firmware: CP3905.9-4-1SR2-2

What could be causing this issue?

Regards

Leonardo Santana
