It's probably not a bug. In any case, what you should do is enable detailed tracing for CallManager, open a TAC case, and get a CCM trace file from a timestamp where you saw one of the Event Viewer messages.
Have found the problem.In the services parameter there is a flag set to true that causes the callmanager to try another gateway in the route list if it gets a busy signal from the PSTN.So basically everytime the user dialled a number that was engaged it caused an error in the event log.Turned it off and everything ok.Thanks for your help anyway.
