I'm not sure if there is a correlation or not, but over the last month or two since I upgraded to 1.02.04e, several times the base unit has not been able to contact one or both of my 2 gateways. I do know that in the couple of months I had the system before the firmware upgrade, this never happened, but the timeframe is too short to be certain that the upgrade and this behavior necessarily have anything to do with each other.
I'm guessing that, on the occasion I lost both, it was due to one having been lost, me not noticing (but still having outside lines - 3 on each gateway) and then the other one going out some time later.
I am also not sure whether they are rebooting, then failing to reconnect, or otherwise locking up. I do know, however, that the *only* way I've been able to get the base unit to recognize them again (with multiple attempts and variations at power-cycling and/or pressing the reset button failing) is to remove them from the base unit in Administrator, reboot them, and add them again.
So this may or may not be the same as the reboot problem seen in a couple other threads (this has only happened a few times, not multiple times daily), so I wanted to differentiate it with a new thread.
