lots of errors on 2431 iad, possible denial of service?

Phones stopped working. Getting these in the logs. Rebooted and that fixed it. Dunno if it's an issue with the firmware, or denial of service attack. Had a couple IADs have this problem at the same time and they are in similar ip space so thinking maybe it's a ddos somehow. If so, is there some config I can put on these things to prevent this type of issue? Only ports 1720 and 5060 are open to the public

it is pingable from anywhere, so I suppose that could be a problem. I'll make it so only we can ping it and not the general public.
