we have a problem with phone resets. without any reasons the phones reloads (not all but 50% of the phones) , we do have the latest phoneload but not the latest CCM service release (3.3(3)). Is it rather a network problem, readjustment of the keepalive timers (default 30 sec) phones to CCM. or rather a problem with the cat switches or CCM service release.
If anyone does have a clue please feel to respond:-)
