I have a TAC case opened up already but things are moving slow so I wanted to put out some feelers. I have to clusters. One was an upgrade from 4.1(3) and one was a new 5.X install. Now they are both running 5.1(2). I have been noticing some strange issues off and on. Like I have random Directory Numbers that I cannot call. They can call other DN's but just cant call it. If you delete/add the phone it starts working again or if I add the line to another phone as a shared line then remove it I can then call the DN again. Other things that I see is some users phones are call forwarded but there is not visual indication on the phone that the it is call forwarded. To work around it the user call forwards their phone somewhere and then un-call forwards the phone. Anyway, strange problems like this are happening off and on that would lead me to believe there is a database synchronization problem? Does anyone know of bugs or have been witness to strange things like this.
FYI, Call Manager Reboot also clear up problems for that time being.
