This just started about a week ago. The phone server has the correct time, the AltiView/AltiAgent clients have the right time. But on the IP 600 the time only updates the time after the phone has been taken off hook. I am at Release 5.0A update 5. I have wiped and reloaded the phones, reloaded the firmware to no avail. It started on all 10 of my phones at once.
