Cisco 7936 IP Conference Station causes packet errors on switches

Unanswered Question
Jun 22nd, 2009

On the port that the Cisco 7936 Conference phone is plugged into it is reporting a large number of undersized packets. This is happening with all of the locations that have this phone. I updated the firmware and it is still having the same problem. Any ideas?


I have this problem too.
