According to Comdial Seconds of silence should be set to 10 and seconds of non silence set to 99.
In COS for the MB's make sure the maximum recording time is set to an appropriate length for your customer, default is 60 secs.
Beyond that the only thing that makes these systems go screwy is if it's used heavily it needs to defrag more then once a week. If you need to set that up post again, I'll have to pull my notes.
