that timer indeed is the connected timer, ringing is not connected so it's expected to not see it. calls that do not connect do show up as zero duration if you enabled the flag on CDR
i'm really not sure about whether it should show up as 0:00 or if you would get at least 1 second, maybe they count the same as call with zero duration
