We recently applied cmterm-7911_7906-sccp.8-3-4sr1 to correct the DST problem on our 7911 phones. We've had a couple of the 7911 phones "drop out" and go into Configuring IP mode. PC network connection through phone remains active, but the 7911 seems to hung at this point. Resetting the phone by pulling the network jack out and in again corrects the problem for awhile.
