SQL is failing to replicate between your publisher and your subscriber CallManager servers. That's a fairly serious problem; it'll prevent any config changes from being sent down to the subscribers. Your cluster is pretty sick right now and it needs to be fixed.
There's a variety of things that could have happened. There's ways to repair the replication, but we'd have to know more about what exact state it's in and where it's breaking down. Rather than drag this out on NetPro, I would really advise you open a TAC case on this. They're very experienced at fixing this sort of stuff, and they can tell you the right thing to do after looking at the current state of your cluster.
