This phone has serious bugs in it. I can't believe it even made it out of the lab.The features are great and all work OK for a while, but before long (8-24 hours) it croaks. So far we've seen 3 things happen:- It stops ringing (it knows there's an incoming call and the lights flash, but it makes no sound),- The mic shuts off (you can make a call, but the person on the other end can't hear anything), or- It just locks up.Each time, it starts working again if you power-cycle it, just to have one of the same problems happen again after a while.Check the various online problem-discussion forums and you'll see that mine is not an isolated case by any means.
