We have problems at least with 2 Cisco 7920 phones with the same firmware version (3.3-01-06), Maybe this firmware be 3.0 version?. The problem is that the phone does suddenly shut down. We have another 7 o 8 phones with the same firmware and this does not happens, and in the "Hardware version" info on the phone seems to be the same: 2.0
It is not a battery problem because I changed this 2 batteries for an "extended" batteries (2400 mA), and the shut down also happens with full charge. We also had tried to change one of the problematic phones but with the new 7920 also does happens this power issue. Could this be a bug?
