Hi team , I have one CUCM in 12.5 and recently, after having had some problems with certificates, and I don't even think it's the problem, but at least it was a coincidence, the dx650 phones started to randomly deregister in cucm, they lost the phone service and we got error messages about energywise. So it seems to us to be energyise problems but apparently we have it disabled on the phones and I'm not sure where to start to solve the problem. It even seems to be a problem or change in the sw's but I also think that the phone should not send requests for energywise.
Phone display show "phone services is unavaiable" and if we disconnect phone cable and plug it again it start work , or if we press Lock key during 5 or 6 sec , we have the option to reset phone and start works as well.
In the phone logs I see this: ### tis is translation from Portuguese to English"
Phone disconnect error : Unable to disconnect, the phone must have connectivity to a cisco switch with energywise technology with a compatible version of energywise enabled.
...This error appears a few times and then I get another one:
CUCM x.x.x.x TCP connection closed
In other words, it seems that the phone is trying to negotiate energywise and as there is no answer, it disconnects the TCP connection and it runs out of telephone services.
Any idea?
