We are runing several different types of C-6500's, all recently upgraded to s72033-ipservicesk9-mz.122-33.SXI9, the 7945 phones are running SCCP45.9-2-1S.
Randomly phones accross several switches, no common switch, port or card, will lose power, but the port for that switch still shows up/up. This is resolved by reseting the card and turning off port security or just resetting the card. Power allocation is not the issue, there is more than required. Below is what we see when one of the phones is off. This does not appear to happen to a phone twice, once this is done it seams to stay up, but it will then happen to another phone or group of phones.

The only change made has been the IOS update, everything else is as it has been prior to the upgrade.
Thanks for the replay, I will run that when I get a chance, but do you have any other possible causes. These where all working correctly before the IOS was upgraded to s72033-ipservicesk9-mz.122-33.SXI9. Also the problem has not resurfaced once everything was reset.
We had another power outage in the same building where we lost the card a week ago. Again we had power issues with phones. Not just individual, sporadic ports, but a logical group of ports. I cleared the problem by doing a shut/no shut range command on the ports affected. It spanned two different cards. So it wasn't just one card.
The real issue is any time we have an outage we will have check to make sure all of the ports have come up correctly. In this case we were at work and all was fixed quickly. Certainly this IOS does not like something.
I'm not able to access my old voice mail messages all of a sudden. The recording says something like 'the message is currently not available'. This has never happened before in all the years I have been using this system. I have t...
