[cisco-voip] TLS Error on Phone after reset

[Chris Ward (chrward)]

What is the model and firmware version of the phones facing this issue? Is it all phones or just a subset?

Hello group

we have a problem with our phones that started this afternoon. If a phone restarts for any reason (reset oder network unplugged) it shows a TLS Error (TLS Error: [CUCM IP]).
We can fix the problem, when we go to the device in the CUCM Administration and choose Install/Upgrade in the CAPF Information section.
After resetting the Device the IPPhone starts and updates the  certificate.

What could cause such a behaviour and how could we fix it?
We have a CUCM 7.1(3a) and have the phones authenticated.
Thanks Reto
