We have 112 Cisco phones on a CCM 3.3 Publisher and Subscriber here at Mesa Verde National Park. It has been installed since 2004 with very few VoIP related problems experienced since then. About 65 of these phones are 7912 models. We started experiencing random intermittent broadcast storms on our network last July and have not been able to trace their source. Just last week, we discovered two 7912 phones that would consistently not register with CCM. They appeared to be locked up. We discovered this because we were trying to chase a broadcast storm problem that came up when a CAT 3550 was replaced because of failure.
What I am looking for is some feedback regarding 7912 intermittent problems and failures that would cause a network storm. Is this common, not so common or does anyone just think I am crazy?
